Solid magnesium carbonate is placed in a solution of hydrogen bromide (also called bromic acid). The two substances react, producing carbon dioxide gas, liquid water, and magnesium bromide which remains in solution. Write a word equation for the above reaction. Write a skeleton equation for the above reaction, using the correct formula for each compound. Write a balanced chemical equation for the above reaction. What are the answers for this please help this is my quiz and answer fast please

Explanation:

Word Equation;

Reactants; Solid magnesium carbonate and hydrogen bromide

Products: Carbon dioxide, liquid water and magnesium bromide

Solid magnesium carbonate +  hydrogen bromide --> Carbon dioxide + liquid water + magnesium bromide

Skeleton Equation:

MgCO3 (s) +  HBr (aq) → MgBr2 (aq) + CO2 (g) + H2O (l)

Balanced Chemical Equation;

MgCO3 (s) + 2 HBr (aq) → MgBr2 (aq) + CO2 (g) + H2O (l)

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
