Answer:
The particle theory is used to explain the properties of solids, liquids and gases. The strength of bonds (attractive forces) between particles is different in all three states.
Explanation:
Explanation:
Standard formation of an substance is defined as formation of one mole of substance from its constituting elements.
Chromium(III) nitrate is composed of chromium, nitrogen and three oxygen atoms.
A balanced chemical equation for the standard formation reaction of solid chromium(III) nitrate
The volume that 0.878 mol occupy at the same temperature and pressure is calculated as follows
if 0.274 mol occupy 6.62 L what about 0.878 mol
by cross multiplication
=0.878 x6.62/0.274=21.21 L
Exothermic reactions<span> are chemical </span>reactions<span> that release energy. Example: Burning a candle is an example of an </span>exothermic reaction<span> because energy is being released during the </span>reaction<span> in the form of heat. </span>Endothermic reactions<span> are chemical </span>reactions<span> that absorb energy.</span>
