13. If a chemist has 12.3 moles of N H 03, what is the mass of the sample?
Answer:
209.4831 g
Explanation:
number of moles × molar mass = mass of substance in g
12.3 × ( 14.0067 + 1.00484 × 3 ) = 209.4831 g

what is atomic number of sodium
Answer:
Explanation:
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is ²³Na. The free metal does not occur in nature, and must be prepared from compounds.
Answer: Atomic number for sodium is 11
Symbol: Na
Melting point: 207.90°F (97.72°C)
The electronic configuration of sodium is 2, 8, 1

What do properties of matter tell us about a substance?
Answer:
Chemical properties of matter describes its "potential" to undergo some chemical change or reaction by virtue of its composition. What elements, electrons, and bonding are present to give the potential for chemical change. It is quite difficult to define a chemical property without using the word "change"

Calculate the number of moles of NaOH contained in 250. mL of a 0.05M solution?
Answer:
0.0125 moles of NaOH are present
Explanation:
Molarity, M, is an unit of concentration widely used in chemistry. Is defined as the ratio between moles of solute (In this case, NaOH) and liters of solution.
250.0mL are = 0.250L of solution. As the molarity of the solution is 0.05M = 0.05moles / 1L, the moles present are:
0.250L * (0.05moles / 1L) =
0.0125 moles of NaOH are present(Science) Help Please!

For a theoretical yield of 5.52 g and percent
yield of 51.7877%, calculate the actual vield
for a chemical reaction.
Answer in units of g.
Answer:
2.85868104g
Explanation:
Actual yield
Theoretical yield x 100 = 51.7877%
So, do the inverse and you get 2.85868104g
When magnesium reacts with sulfuric acid the products are magnesium sulfate and hydrogen. If there are 15 grams of magnesium at the start of the reaction, how much magnesium will be present in the magnesium sulfate
Answer: 15 grams of magnesium will be present in the magnesium sulfate
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.
The balanced chemical reaction is:
[tex]Mg+H_2SO_4\rightarrow MgSO_4+H_2[/tex]
As the mass remains conserved at the end of the reaction, there will be 15 grams of Magnesium in magnesium sulphate.
3) A child has a toy balloon with a volume of 1.8 liters. The temperature of the balloon when it was filled was 22° C and the pressure was 1.0 atm. If the child were to let go of the balloon and it rose into the sky where the pressure is 0.86 atm and the temperature is 8° C, what would the new volume of the balloon be?
This is a combined gas law problem, according to which
[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]
where P is the pressure of the gas, V is the volume of the gas, and T is the temperature of the gas, and the subscripts 1 and 2 correspond to the initial and final conditions of the gas. In this problem, we are given the initial pressure, volume, and temperature of the gas in the balloon:
P₁ = 1.0 atm
V₁ = 1.8 L
T₁ = 295.15 K (K = °C + 273.15).
Moreover, we are given the final pressure and temperature of the gas in the balloon.
P₂ = 0.86 atm
T₂ = 281.15 K.
What we want to find is the final volume, V₂, which we can obtain by rearranging the combined gas equation to solve for V₂:
[tex]V_2=\frac{P_1V_1T_2}{T_1P_2} = \frac{(1.0 \text{ atm})(1.8 \text{ L})(281.15 \text{ K})}{(295.15 \text{ K})(0.86 \text{ atm})} \\ V_2 = 1.99 \text{ L}[/tex]
This answer has three significant figures. However, the question as written would warrant an answer that comprises one significant figure (as 8 °C has only one sig fig). In that case, the answer would be 2 L. If the answer is to be given to two significant figures, the volume would then be 2.0 L.

If the mass of all the reactants in a chemical reaction is 100g, what will the mass of all products be?
How many moles are in 281 g of Ca(OH)2?
Answer:
3.79 moles
Explanation:
To convert moles to gams of a substance we need to find the molar mass of the substance. For Ca(OH)₂ th molar mass is:
1Ca = 40.08g/mol
2O = 2*16g/mol = 32g/mol
2H = 2*1.01g/mol = 2.02g/mol
The molar mass is:
40.08g/mol + 32g/mol + 2.02g/mol = 74.1g/mol
And moles are:
281g * (1mol / 74.1g) =
3.79 moles0.32 moles of oxygen gas has a temperature of 27°C and pressure of 2 atm in a closed container. What is the volume?
Answer:
3.9 L
First convert temperature to Kelvin
then use the ideal gas law
use algebra to solve for V
Since your solving for volume, your answer should be in Liters.

What would happen to a plant that did not perform cellular respiration in the light?
Answer:
Explanation:
Cellular respiration does not depend on light... Some plants may go into a form of hibernation during winter when the amount of light during the day is less. The reduction of plant growth and activity would reduce the need for the energy produced by cellular respiration.
