2C + O2 = 2CO is balanced.

If you look you can see the first side has 2 Cs and 2 Os, and the other side has the same amount, just put together making both sides even and balanced.

Solid silver chloride, AgCI(s), decomposes to its elements when exposed to sunlight Write a balanced equation for this reaction

Mrac [35]

Answer: The coefficient in front of AgCl when the equation is properly balanced is 2.

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. Thus chemical equations are balanced.

Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Decomposition of silver chloride is represented as:

$2AgCl(s)\rightarrow 2Ag(s)+Cl_2(g)$

Thus the coefficient in front of AgCl when the equation is properly balanced is 2.

seropon [69]

Answer:

B. an air-conditioning system.

Explanation:

Refrigeration is defined as a process of cooling a system to lower temperature below the surrounding temperature while the removed heat is rejected at higher temperatures.

Heat pumps use the heat output of the refrigeration process, which may also be designed to be reversible, but are otherwise similar to air conditioning units.
