Step 1 - Balancing the combustion equation
The combustion of an alkane always gives, as products, H2O and CO2. Remembering that combustion always involves a reaction with O2, we can write the chemical equation for the combustion of C4H10 as:
[tex]C_4H_{10(g)}+\frac{13}{2}O_{2(g)}\rightleftarrows4CO_{2(g)}+5H_2O[/tex]Step 2 - Discover how many grams of carbon dioxide can be produced
Looking at the equation above, we can see that 1 mole of C4H10 produces 4 moles of CO2. This is a fixed proportion. We can convert this proportion in moles to a proportion in mass by multiplying each number of moles by the respective molar mass (C4H10 58g/mol; CO2 44g/mol)of the substances:
[tex]\begin{gathered} mC_4H_{10}=1\times58=58\text{ g} \\ \\ mCO_2=4\times44=176\text{ g} \end{gathered}[/tex]We discovered thus that each 58 g of C4H10 produce 176g of CO2. Since this is a fixed proportion in mass, we can use it to discover how many grams of CO2 would be formed by the combustion of 20g of butane (C4H10):
[tex]\begin{gathered} 58\text{ g of C4H10------ 176 g of CO2} \\ 20\text{ g of C4H10 ----- x} \\ \\ x=\frac{176\times20}{58}=60.7\text{ g of CO2} \end{gathered}[/tex]The combustion of 20 g of C4H10 would produce thus 60.7 g of CO2.

The pressure exerted by 1.30 mol of gas in a 13.0 L container at 295 K is
Answer:
The pressure of the gas is 2.42atm.
Explanation:
The given information from the exercise is:
- Number of moles (n): 1.30 moles
- Volume (V): 13.0L
- Temperature (T): 295K
With the Ideal Gases Law formula we can calculate the pressure (P) of the gas, by replacing the values of n, V and T:
[tex]\begin{gathered} P*V=n*R*T \\ P*13.0L=1.30mol*0.082\frac{atm*L}{mol*K}*295K \\ P*13.0L=31.45atm*L \\ P=\frac{31.45atm*L}{13.0L} \\ P=2.42atm \end{gathered}[/tex]So, the pressure of the gas is 2.42atm.

Infer how resting membrane potential would be affected if the membrane were only permeable to potassium ions.
Option 1) If the cell were only permeable to potassium ions there would be a drastic change in membrane potential to a more positive value as potassium enters the cell
Option 2) If the cell were only permeable to potassium ions there would be a slight change in membrane potential to a more negative value as potassium exits the cell.
Option 3) If the cell were only permeable to potassium ions there would be a drastic change in membrane potential to a more negative value as potassium leaves the cell.
According to the research, the correct answer is Option 2. If the cell were only permeable to potassium ions there would be a slight change in membrane potential to a more negative value as potassium exits the cell.
What is resting membrane potential?It refers to the potential difference on either side of the membrane of a resting cell, that is, already repolarized where the channels are much more permeable to potassium than to sodium.
In this sense, it is determined by the ion concentration and membrane permeability where the inside of the cell has a more negative charge (potassium ions) relative to the outside (sodium ions).
Therefore, we can conclude that resting membrane potential causes the cell membrane inside to become negative because it has sodium ions towards the outside of the cell and potassium ions towards the inside, thus the correct answer is Option 2.

AlCl3 has a higher charge density which makes the polarization to be high. Therefore AlCl3 has a higher covalent character (stronger bonding).
Covalent character and cationic size are indirectly related to each other. When the size of a cation is smaller, the covalent character would be higher.
In MgCl2, the cation is Mg^2+ and in AlCl3, the cation is Al^3+. The size of Mg^2+ is larger when compared to the size of Al^3+. That is why the covalent character of AlCl3 is larger.

Firstly, we need to convert the 100 g of AlCl₃ to number of moles, using:
[tex]M_{AlCl_3}=\frac{m_{AlCl_3}}{n_{AlCl_{3}}}[/tex]The molar weight of AlCl₃ is calculating consulting the atomic weights:
[tex]\begin{gathered} M_{AlCl_3}=1\cdot M_{Al}+3\cdot M_{Cl} \\ M_{AlCl_3}=(1\cdot26.982+3\cdot35.453)g/mol \\ M_{AlCl_3}=(26.982+106.359)g/mol \\ M_{AlCl_3}=133.341g/mol \end{gathered}[/tex]Thus:
[tex]\begin{gathered} M_{AlCl_3}=\frac{m_{AlCl_3}}{n_{AlCl_3}} \\ n_{AlCl_3}=\frac{m_{AlCl_3}}{M_{AlCl_3}}=\frac{100g}{133.341g/mol}=0.749957\ldots mol \end{gathered}[/tex]For each 2 moles of AlCl₃, we produce 3 moles of CaCl₂. So:
2 mol AlCl₃ --- 3 mol CaCl₂
0.749957... mol AlCl₃ --- x
[tex]\begin{gathered} \frac{2}{0.749957\ldots mol}=\frac{3}{x} \\ 2x=2.24987\ldots mol \\ x=1.12494\ldots mol \end{gathered}[/tex]Now, we convert back to grams, but now we need the molar weight of CaCl₂:
[tex]\begin{gathered} M_{CaCl_2}=1\cdot M_{Ca}+2\cdot M_{Cl} \\ M_{CaCl_2}=(1\cdot40.078+2\cdot35.453)g/mol \\ M_{CaCl_2}=(40.078+70.906)g/mol \\ M_{CaCl_2}=110.984g/mol \end{gathered}[/tex]Thus:

If the freezing point of a soda is – 4.5 ºC and you leave it in your car overnight when the temperature dips to 25 ºF, will the soda freeze? (Pay close attention to the units!)
Explanation:
We leave a soda in the car overnight and the temperature dips to 25 °F. To see if it will freeze we have to convert the °F to °C.
T(°C) = ( T(°F) - 32 ) *5/9
T(°C) = (25 - 32) *5/9
T(°C) = -3.9 °C
Since -3.9 °C is a temperature greater than the freezing point (-4.5 °C) the soda won't freeze.
Answer: The soda won't freeze.
I need to balance the equation __kciO3➡️__kcio4+__ KCIAnd How many moles of potassium chloride are produced from 3.90 moles of potassium chlorate ?
Explanation:
To balance the equation, we need to have the same number of atoms of each element on both sides of the equation.
So in this case:
4KCIO3 → 3KCIO4 + KCI
where:
reactants:
K - 4
Cl - 4
O - 12
Products:
K - 4
Cl - 4
O - 12
Potassium chloride is KCl and potassium chlorate is KClO3. The balanced reaction equation tells us that:
4 mol of KClO3 produces 1 mol of KCl, we know it because of the equation:
4 KCIO3 → 3 KCIO4 + 1 KCI
So we can do a rule of 3 to find out the quantity in moles produced when we have 3.90 moles of KClO3:
4 mol KClO3 --- 1 mol KCl
3.9 moles KClO3 --- x
4x = 1*3.9
x = 3.9/4
x = 0.975 moles
Answer: 4 KCIO3 → 3 KCIO4 + KCI and 0.975 moles.
A gas's volume decreases. Which of the following could most easily explain that?a. Its temperature increased.b. Its pressure increased.c. Its energy content increased.d. Its density decreased
This is an ideal gas problem, so let's see the relationships of volume with pressure and temperature:
- The relationship between volume and pressure is inversely proportional.
- The relationship between volume and temperature is directly proportional.
When the gas's volume decreases, the temperature would decrease too but the pressure would increases, so the answer would be B. Its pressure increased.
What's the volume of 0.2 mol of nitrogen at 20oC and 0.7 atm?
Explanation:
We have to determine the volume of 0.2 mol of nitrogen at 20 °C and 0.7 atm. The ideal gas law describes this situation.
P * V = n * R * T
Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant and T is the temperature.
We already know these some of these values.
P = 0.7 atm
n = 0.2 mol
R = 0.082 atm * L/(mol*K)
T = 20 ° C = 293.15 K
We can use the ideal gas law to determine the volume of the sample.
P * V = n * R * T
V = n * R * T/P
V = 0.2 mol * 0.082 atm*L/(mol*K) * 293.15 K/(0.7 atm)
V = 6.86 L
Answer: The volume is 6.86 L.
The equation for the synthesis of ammonia is N2 + 3 H2 -> 2 NH3. How many moles of H2 I needed to produce 6 mol of NH3? A. 4 B. 6 C. 8 D. 9
The equation for the synthesis of ammonia is:
N₂ + 3 H₂ ---> 2 NH₃
We have to find the number of moles of H₂ needed to produce 6 mol of NH₃. To do that we will use the equation that we were given.
We can read the equation of the reaction as a recipe. When 1 mol of N₂ reacts with 3 moles of H₂, 2 moles of NH₃ are produced. So the relationship between H₂ and NH₃ is that 3 moles of H₂ are needed to produce 2 moles of NH₃. We wiill use that relationship to solve the problem.
6 moles of NH₃ * 3 moles of H₂/(2 moles of NH₃) = 9 moles of H₂
Answer: D) 9 moles of H₂ are needed.
REACTION; C5H12 + 8O2 5CO2 + 6H2OWhen 35.5 L of C5H12 are consumed in this reaction what volume of CO2 can be produced in liters?
Using the STP (standard temperature and pressure), we can solve this problem. First, let's find the number of moles produce by 35.5 L of C5H12.
Remember that the standard temperature is 0 °C which is the same that 273 K (kelvin) and for pressure is 1 atm and the constant of ideal gas is 0.082 atm*L/(mol*K)
Let's use the formula of an ideal gas to find the number of moles:
[tex]\begin{gathered} PV=\text{nRT,} \\ n=\frac{PV}{RT}, \\ n=\frac{\text{1 atm }\cdot35.5\text{ L}}{0.082\frac{atm\cdot L}{mol\cdot K}\cdot273K}, \\ n(C_5H_{12})=1.58\text{6 moles} \end{gathered}[/tex]Now, using this number of moles, we can find the number of moles produce for CO2 and we can find its volume.
You can see that in the reaction 1 mol of C5H12 produces 5 moles of CO2, so the calculation to find the number of moles of CO2, would be:
[tex]1.586molC_5H_{12}\cdot\frac{5molCO_2}{1molC_5H_{12}_{}}=7.93molCO_2.[/tex]The next and final step is clear V (volume) from the initial formula and replaces the value of moles for CO2, like this:
[tex]\begin{gathered} V=\frac{nRT}{P}, \\ V=\frac{7.93\text{ mol}\cdot0.082\frac{atm\cdot L}{mol\cdot K}\cdot273K}{1\text{ atm}}, \\ V(CO_2)=177.52\text{ L.} \end{gathered}[/tex]So, 25,5 L of C5H12 will produce 177.52L of CO2.

The equilibrium for the above reaction can be calculated using this equation:
Kc = [NO₂]/([N₂]^(1/2)*[O₂]) where the concentrations are the equilibrium concentrations.
According to the graph the concentration in the equilibrium of each compound is:
[NO₂] = 6 mol/L
[N₂] = 10 mol/L
[O₂] = 20 mol/L
If we replace these values in the given equation:
Kc = [NO₂]/([N₂]^(1/2)*[O₂])
Kc = (6 mol/L)/[(10 mol/L)^(1/2)*(20 mol/L)]

7. How many moles of NH3 can be produced from5.00 moles of H, according to the following equation?N2 + 3 H2 → 2 NH3a. 0.67 molb. 2.00 molc. 3.33 mold. 7.50 mol
Answer:
[tex]C\text{ : 3.33 mol}[/tex]Explanation:
Here, we want to get the number of moles of ammonia that could be produced from 5 moles of hydrogen
From the balanced equation of reaction, 3 moles of hydrogen produced 2 moles of ammonia
5 moles of hydrogen will produce x moles of ammonia
Mathematically:
[tex]\begin{gathered} 5\times2\text{ = 3}\times x \\ x\text{ = }\frac{10}{3} \\ x\text{ = 3.33 mol} \end{gathered}[/tex]
