The reaction produces 6 g of carbon dioxide.
The word equation is
methane + oxygen → carbon dioxide + water
12.2 g + 4 g → x g + 20 g
The <em>Law of Conservation of Mass</em> tells us the total mass of the reactants must equal the mass of the products. Then
12.2 g + 14 g =<em> x</em> g + 20 g
<em>x</em> = 12.2 + 14 – 20 = 6
The mass of carbon dioxide is 6 g.
<em>Note</em>: The answer can have <em>no decimal places</em> because you gave none for the masses of oxygen and water.
Answer:
a. MgO(s) + H2CO3(aq) → MgCO3(s) + H2O(l) DOUBLE DISPLACEMENT REACTION.
b. 2KNO3(s)→2KNO2 (s) + O2(8) DESCOMPOSITION REACTION.
c. H2(g) + CuO(s) → Cu(s) + H2O(1) SINGLE DISPLACEMENT REACTION.
d. NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(1) COMBUSTION REACTION.
e. H2(8) + Cl2(g) → 2HCl(8) SYNTHESIS REACTION.
f. SO3(g) + H2O(1)→ H2SO4(aq) SYNTHESIS REACTION.
Inhalation is the process of taking air into the lungs. For this to occur, the air pressure inside the lungs must be lower than that of the external atmosphere as air flows from areas of higher pressure to lower pressure. <span>Exhalation is the process of expelling air out of the lungs. For this to occur, the air pressure inside the lungs must be higher than that of the external atmosphere as air flows from areas of higher pressure to ones of lower pressure.</span>
This is the decomposition reaction, namely the reaction of photolysis.
2AgCl = 2Ag + Cl₂
