States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Question
Writing and Balancing Chemical Equations
Transcribed Image Text:1. For each chemical equation (which may or may not be bal-
anced), list the number of each type of atom on each side of
the equation, and determine if the equation is balanced.
(a) Pb(NO3)2(aq) + 2NACI(aq)
32. For each chemical equation (which may or may not be bal-
anced), list the number of each type of atom on each side of
the equation, and determine if the equation is balanced.
(a) MgS(aq) + 2CUC12(aq) → 2CuS(s) + MgCl2(aq)
(b) 2C,H14(1) + 1902(8) 12CO2(8) + 14H,O(g)
PBCI2(s) + 2NaNO3(aq)
(b) CHg(g) + O:(g).
→ 3CO2(g) + 4H2O(g)
