Answer:
If it contains only 2 elements it will begin with “hydro” as in
hydrochloric acid (HCl). If it contains more than 2 elements it is named based on the polyatomic (oxy) anion, as in nitric acid (HNO3), nitrous acid (HNO2), sulfuric acid (H2SO4). If the element has more than one possible charge, the value of the charge comes after the element name and before the word ion. Thus, Fe 2+ is the iron two ion, while Fe 3+ is the iron three ion.
Explanation:
The best method to solve how many grams of sodium nitrate that will be dissolve in water at 20 degrees Celsius is to use solubility table. Based on the solubility table, 88.3 g will dissolve in water in a 100g NaNO3. Therefore, get the percentage and multiply it to 50g. The answer is 44.15g
A) The atomic mass can vary based on the number of neutrons the atoms of the same element have, so the atomic mass may not be in order. Also, the atomic number is unique to each element.

<span>60. 4Li(s) + O2(g) >>>>>>>>>>> 2Li2O(s)
moles O2 required = (84 grams Li) * (1 mol Li / 6.941 grams Li) * (1 mol O2 / 4 mol Li) = 3.026 moles O2 required.
PV = nRT, P = 1 atm, V = ?, n = 3.026 moles, R = 0.0821 L*atm/mol*K, T = 273 K
(1 atm)*(V) = (3.026 moles O2) * (0.0821 L*atm/mol*K) * (273 K)
V = 67.82 Liters is the answer.

CH4 + 2O2 → CO2 + 2H2O
<h2>
Explanation:</h2>
10 grams of methane reacts with 40g of oxygen in the air. This means that mass from the oxygen in the air is also present in the carbon dioxide, so the mass can appear to increase, whereas in reality it is the mass of the oxygen that has caused the increase.
This reaction obeys the law of conservation of mass. Even though it may to appear so until balanced, all reactions follow the law.
