What is true of a decomposition reaction? the reactants are usually a metal and a nonmetal. the reactants are generally two ionic compounds in an aqueous solution. the addition of energy in the form of heat or electricity is often required. water is usually one of the reactants.

Answer

In a true decomposition reaction, the addition of energy in the form of heat or electricity is often required.

Explanation

A decomposition reaction is a chemical reaction that starts with single reactants to give new compounds as the products. These reaction requires a source of energy that could be light, heat  or electricity to facilitate the breaking-down of the chemical bonds.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
