Answer:
Equation is: 2CH4(g) <----> C2H2(g) + 3H2(g)
Explanation:
In the reaction above;
1.) At equilibrium, the rate of the forward reaction (CH4 decomposing into C2H2 and H2) is equal to the rate of the reverse reaction (C2H2 and H2 reacting to form CH4). This is because it is a reversible reaction.
2.) At equilibrium, the concentrations of all substances are not changing.
3.) At equilibrium, both the forward and reverse reactions are still occurring.
But if the pressure of the system is increased, the equilibrium position will shift to the left according to le Chatelier's principle since there are fewer number of moles of gaseous atoms at the left.
The balanced chemical reaction would be:
<span>2NI3 = N2 + 3I2
We use the reaction above and the molar masses of the substances involved. We start with the initial amount of NI3 reactant.
3.58 g NI3 (1 mol NI3 / 394.71 g NI3) (3 mol I2 / 2 mol NI3) = 0.0136 mol I2
Therefore, option C is the answer.</span>
Answer:
24000
Explanation:
Given that:
The numbers of carbon atoms = 8000
According to the Einstein model of solid;
Einstein’s model assumes that each atom of the solid vibrates around its position of equilibrium independently of the other atoms (which amounts to neglecting the interactions between particles.
Number of oscillators = 3(8000)
Number of oscillators = 24000
79470.2mL
Explanation:
Given:
Volume = 21gallons
problem, convert to milliliters;
gallons to milliliters
1 liter = 1.057 quarts
1 gallon = 4 quarts
we can simply solve this by establishing and using a conversion factor of 1 ;
1 gallon = 4 quarts
1.057 quarts = 1 liter
0.001L = 1mL
21gallons x
= 79470.2mL
we say;
From; 
1gallon = 3784.2mL
