How would you describe the following chemical reaction?

Chemistry
1 answer:
GREYUIT [131]2 years ago
4 0

Answer:

B

Explanation:

The normal way to express an energy reaction is to put the energy on the left. Then you can make a rule.

  • If the energy on the left is plus then the reactants require energy. The reaction is endothermic -- energy is taken from the environment.
  • If the energy is minus when it is on the left. then the reactants give up energy. The reaction is exothermic and energy is given to the environment.

2CO(g)+O2(g) - energy --> 2CO2(g)

Exothermic

A mixture of 10 cm3 of methane and 10 cm3 of ethane was sparked with an excess of oxygen. After cooling to room temperature, thr
Tpy6a [65]
In the combustion process using excess oxygen, each mole of methane results to 1 mole of co2 while ethane produces 2 moles of Co2. Under same conditions, these can be translated to volume. Hence the total volume absorbed is 10 cm3 + 20 cm3 = 30 cm3.

What stress would shift the equilibrium position of the following system to the left?
Margarita [4]

Answer:

Heating the system

Explanation:

According to the principle of Le Chatelier, for a system at equilibrium, a specific disturbance would make the equilibrium shift toward the direction which minimizes such a disturbance.

Since we wish to shift the equilibrium to the left, this means we wish to increase the concentration of products, as an excess in their concentration would make the products react and produce more reactants in order to lower the excess concentration of products.

Since heat is also a product, an increase in heat would shift the equilibrium toward the left, as this would consume the excess of heat by producing the reactants.
