Answer is: <span>the empirical formula of the hydrocarbon is CH</span>₂.<span>
Chemical reaction: C</span>ₓHₐ + O₂ → xC + a/2H₂O.<span>
m(CO</span>₂) = 33.01 g.
n(CO₂) = m(CO₂) ÷ M(CO₂).
n(CO₂) = 33.01 g ÷ 44.01 g/mol.
n(CO₂) = n(C) = 0.75 mol.
m(H₂O) = 13.52 g.
n(H₂O) = 13.52 g ÷ 18 g/mol.
n(H₂O) = 0.75 mol.
n(H) = 2 · n(H₂O) = 1.5 mol.
n(C) : n(H) = 0.75 mol : 1.5 mol /0.75 mol.
n(C) : n(H) = 1 : 2.
Answer: Water is a reusable resource because it evaporates out of the oceans to clouds, which generate rain falling on the land.
Explanation:
The answer would be b) GAS
The answer is: [D]: " AgCl " .

Explanation:
_________________________________________________________
Given the chemical reaction:
_________________________________________________________
NaCl (aq) + AgNO₃ (aq) <span>→ </span> NaNO₃ (aq) + AgCl (s) ;
_________________________________________________________
The "reactants" , which are on the "left-hand side" of the chemical equation, are:
"NaCl" (in aqueous solution); and "AgNO₃" (in aqueous solution).
The "products", which are on the "right-hand side" of the chemical equation, are:
"NaNO₃" (in aqueous solution); and: "AgCl" (as a "solid").
The "AgCl" (as a "product"—which is a "solid"—would be the "precipitate" ;
__________________________________________________________
→ which is: Answer choice: [D]: " AgCl " .
