<h3>
The Law of Conservation of Mass</h3>
<em>Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.</em>
<em>The Law of Conservation of Matter also states that the matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.</em>

Answer: Answer:- C. The container contains 8 grams of liquid water and no ice.
Explanation:
16 grams.
Looking at the reaction equation, it's evident that for each mole of HBr
consumed, 1 mole of CO2 will be produced. So let's calculate the molar mass
of HBr and CO2 first.
Atomic weight hydrogen = 1.00794
Atomic weight bromine = 79.904
Atomic weight carbon = 12.0107
Atomic weight oxygen = 15.999
Molar mass HBr = 1.00794 + 79.904 = 80.91194 g/mol
Molar mass CO2 = 12.0107 + 2*15.999 = 44.0087 g/mol
Moles HBr = 30 g / 80.91194 g/mol = 0.370773461 mol
Grams CO2 = 0.370773461 mol * 44.0087 g/mol = 16.317258 g
Rounding to 2 significant digits gives 16 grams.
