One of the most important chemical reactions is the haber process, in which n2 and h2 are converted to ammonia which is used in the production of fertilizers. Consider that you have just produced 170 g of nh3 in a 50. 0 l tank at 400. 0 c. What was the total pressure of the gases that reacted to produce this ammonia?.
The total pressure of the gases that reacted to produce ammonia is 22 Pa.
Considering the following balanced equation of the Haber process;
N₂(g) + 3 H₂(g) ----> 2 NH₃(l)
According to the balanced equation, 34.0 g of NH₃ are produced by 1 mol of N₂ as the molar mass of NH₃ is 17g/mol
Now calculating for 170 g of NH₃ as follows;
170g NH₃ × ( 1 mol N₂ / 34 g of NH₃) = 5 mol N₂
Similarly; According to the balanced equation, 34.0 g of NH₃ are produced by 3 moles of H₂, therefore calculating for 170 g of NH₃ as follows;
170g NH₃ × ( 3 mol H₂ / 34 g of NH₃) = 15 mol H₂
The total gaseous moles before the reaction were;
5.00 mol + 15.0 mol = 20.0 mol.
Now we can determine the total pressure (P) by using the ideal gas equation.
P.V = n.R.T
where
V is the volume (50.0 L)
n is the number of moles (20.0 mol)
R is the ideal gas constant (0.08206atm.L/mol.K)
T is the absolute temperature (400.0 + 273.15 = 673.2K)
P = n.R.T / V
P = (20.0 mol × 0.08206atm.L/mol.K × 673.2K) / 50 L
P = 22 atm

Configurational isomers are stereoisomers that can't be transformed into each other via rotating the molecule around a single bond. those configurational isomers may be found in kinds such as geometrical isomers and optical isomers.
Enantiomers are pairs of compounds with precisely equal connectivity however contrary to three-dimensional shapes. Enantiomers aren't the same as every different; one enantiomer can not be superimposed on the alternative. Enantiomers reflect images of every different.
Diastereomers are a kind of stereoisomer. Diastereomers are described as non-mirror pictures, non-same stereoisomers. hence, they arise whilst two or greater stereoisomers of a compound have specific configurations at one or greater of the equal stereocenters and aren't replicate pics of every different

Write a balanced equation for the complete oxidation reaction that occurs when methanol (ch3oh) burns in air.
The balanced equation for the complete oxidation reaction that occurs when methanol CH₃OH burns in air is 2CH₃OH + 3O₂ → 2H₂O + 4CO₂.
When Methane CH₃OH reacts with O₂, it get oxidized and CO₂ and H₂O are formed.
The chemical equation of the oxidation of methane when it burns in the air is,
CH₃OH + O₂ → H₂O + O₂
In order to balance the reaction, we should start first with carbon, then Hydrogen and at the end, we will balance oxygen atoms on both the sides of the reaction,
So, the balanced chemical equation becomes,
2CH₃OH + 3O₂ → 2H₂O + 4CO₂
So, in this reaction, Carbon is getting oxides as it is becoming carbon dioxide by the addition of oxygen into it and Oxygen itself is getting reduced.

Just as you had started with a molecule with two phenyl substituents on the same side, the product has the configuration on each stereocenter the same as the other (R,R; S,S).
If you rotate the central

What are electrolytes and why are they important? (1 pt)
Unit 4 lesson 4-6
Minerals with an electric charge called electrolytes are found in your body. They can be found in various bodily fluids such as urine, tissues, and blood.
Why are electrolytes important?
Our body contains electrolytes, which are minerals with an electric charge. Our blood, urine, tissues, and other bodily fluids all contain them.Electrolytes are crucial because they aid in:
Ensuring that our body is adequately hydrated.Maintain a pH balance in our body.Transfer nutrition to our cells.Clear our cells of wastes.Make sure our heart, brain, muscles, and nerves all function properly.The many electrolytes include sodium, calcium, potassium, chloride, phosphate, and magnesium. They come from the foods we consume and the liquids we drink.
The body's electrolyte levels might get too high or too low when the body's water balance changes. The amount of water we consume and lose should be equal. If something throws off this equilibrium, we can be dehydrated or have too much water on our body (overhydration).
The water balance can be thrown off by a number of factors, including some medications, nausea, diarrhea, perspiration, and liver or kidney issues.
We can regulate the imbalance with the aid of treatment. Additionally, the cause of the imbalance must be determined and addressed.

If the contact area between two objects is
getting warm, what might you conclude?
Answer: The end result is thermal equilibrium.
Explanation: When two objects are touching for a specific period of time heat [thermal energy] always moves from a warmer substance to a cooler substance. In your case we have two objects of unknown temperature. The temperature between those objects is transferred/ conducted. Eventually, the heat conduction between two objects of unknown temperature results in the achievement of thermal equilibrium.
Answer: Thermal equilibrium
Explanation :Heat will transfer thermal energy from the object at higher temperature to the one at lower temperature until they both reach the same temperature. The objects are then in thermal equilibrium, and no further temperature changes will occur if they are isolated from other systems. The systems interact and change because their temperatures are different, and the changes stop once their temperatures are the same. Thermal equilibrium is established when two bodies are in thermal contact with each other—meaning heat transfer (i.e., the transfer of energy by heat) can occur between them. If two systems cannot freely exchange energy, they will not reach thermal equilibrium. (It is fortunate that empty space stands between Earth and the sun, because a state of thermal equilibrium with the sun would be too toasty for life on this planet!)
explain how the direction of electron flow in a voltaic cell is consistent with what you would predict from the activity series
In voltaic cells, electrons flow from the negative electrode (anode) to the positive electrode (cathode).
Electrons are moved from one species to another in redox reactions. When a reaction occurs spontaneously, energy is released that can be put to good use. The process must be divided into the oxidation reaction and the reduction reaction in order to capture this energy. A wire is used to move the electrons from one side of the reactions to the other after they have been placed into two separate containers. A voltaic/galvanic cell is produced as a result.

Ozone in the upper atmosphere (the ozone layer) absorbs light at around 220 nm. what is the frequency???
Answer:
1.36x10^15 Hertz
Explanation:
The wavelength, λ, and frequency, ν, of light are described by the equation:
c = λν
where c is the speed of light (c = 3.0x10^8 m/s)
We are given the wavelength, λ, as 220nm
We'll need this in meters, not nanometers, nm.
1nm = 10^-9m
(220nm)*(10^-9m/nm) = 2.20x10^-7m
v = c/λ
v = (3.0x10^8 m/s)/(2.20x10^-7m) = 1.36x10^15/s or Hertz (1360 terahertz)

3. If you had 30 molecules of H2 and an excess of N2, how many molecules of NH3 would be produced?
1. 2 moles of nitrogen reacting with an excess of hydrogen will produce moles of ammonia6 moles [tex]NH_3[/tex].
2. The number of moles of nitrogen needed to completely react with 12 moles of hydrogen is 4 moles.
3. 30 molecules of hydrogen reacting with an excess of nitrogen will produce 20 molecules of ammonia.
Stoichiometric problemThe balanced equation of the reaction between hydrogen and nitrogen to produce ammonia is as follows:

This means that the mole ratio of [tex]N_2[/tex] to [tex]H_2[/tex] to [tex]NH_3[/tex] is 1:3:2.
If there are 3 moles of [tex]N_2[/tex] an excess of [tex]H_2[/tex]. The mole ratio of [tex]N_2[/tex] to [tex]NH_3[/tex] is 1:2. This means that for every 1 mole [tex]N_2[/tex] that reacts, 2 moles of [tex]NH_3[/tex] are produced.1 mol [tex]N_2[/tex] = 2 mol [tex]NH_3[/tex]
3 mol [tex]N_2[/tex] = 3 x 2
= 6 moles [tex]NH_3[/tex]
The mole ratio of [tex]N_2[/tex] and [tex]H_2[/tex] is 1:3.3 mol [tex]H_2[/tex] = 1 mol [tex]N_2[/tex]
12 mol [tex]H_2[/tex] = 12 x 1/3

Submit Answer.
The rate law in general form for this reaction is:
rate = k[A]^m x [B]^n
and we want to determine m and n.
Notice the experiments conducted involved verifying the concentration of one of the reactants while keeping the other constant. By comparing two experiments in this way and noticing the effect on the reaction rate, one can deduce the order with respect to that reactant.
Take experiments 1 and 2 :
Doubling the concentration of OH⁻ while keeping (CH₃)₃CBr constant had no effect on the initial rate.
This implies the order with respect to [OH⁻] is zero.
From experiments 1 and 3 we see that doubling the [ (CH₃)₃CBr ] while keeping [OH-] the same doubles the initial rate.
We now have the orders of the two reactants, and the rate law will be:
rate = k [ (CH₃)₃CBr ] [ OH⁻]⁰ = k [ (CH₃)₃CBr ]
We could use another comparison to check our answer. For example comparing 3 and 4, maintaining [ (CH₃)₃CBr ] constant and doubling [ OH⁻] has no effect on the rate which confirms the order respect to [ OH⁻] is zero.
The rate constant we can determine it from any of the experiment by solving for k, for example from experiment 1:
7.14 x 10⁻³ M/s = k x 0.626 M ⇒ k = 0.011 s⁻¹
Therefore, the rate constant of the following reaction is 0.011 s⁻¹.
