Chemical equation
<h3>
What is a chemical equation?</h3>
- The reactants and products of a chemical reaction are represented symbolically in a chemical equation by the appropriate chemical formulas.
- A chemical equation that illustrates how Calcium oxide (quicklime) and carbon dioxide are produced during the breakdown of limestone.
CaCo3 → CaO+ CO2 (Decomposition reaction)
- The portion of the chemical equation on the reactant side is to the left of the symbol "→," and the portion on the product side is to the right of the arrow symbol.
<h3>
Decomposition reaction:-</h3>
A chemical reaction that results in the breakdown of one reactant into two or more products is known as a decomposition reaction.

<em>The number of atomic orbitals is the same for all elements in a period. Every element in the top row (the first period), for example, has only one orbital for its electrons. The electrons of all the elements in the second row (second period) have two orbitals. Every row adds an orbital as you progress down the table.</em>

Answer:
C(s) + H2O(g) → CO(g) + H2(g)
Explanation:
Carbon monoxide and hydrogen. Possibly some reaction products from impurities in the coke, but mostly CO and H2.
A. Potassium oxide
B. Calcium chloride
C. Magnesium nitride
D. Sodium hypochlorite
E. Potassium nitrate
If we use 100 grams of compound:
m(C) = 0,7787 · 100 g = 77,87 g.
n(C) = 77,87 g ÷ 12 g/mol = 6,49 mol.
m(H) = 0,0263 · 100 g = 2,63 g.
n(H) = 2,63 g ÷ 1 g/mol = 2,63 mol.
m(O) = 0,5562 · 100 g = 55,62 g.
n(O) = 55,62 g ÷ 16 g/mol = 3,48 mol.
n(C) : n(H) : n(O) = 6,49 mol : 2,63 mol : 3,48 mol.
n(C) : n(H) : n(O) = 2,5 : 1 : 1,33.
From molecular mass only possible is C₁₂H₉O₁₂.
