The right answer for the question that is being asked and shown above is that: "C) carbon monoxide and carbon dioxide" hydrocarbons burn completely in an excess of oxygen, the products are <span>C) carbon monoxide and carbon dioxide</span>
Answer: Yes fertilizers do make plants grow faster but the three combined water, sunlight, and fertilizer they grow much faster.
First convert the given volume of hydrogen gas to grams by
multiplying the volume with the given density. The mass of hydrogen gas is
22.50197 grams. Then convert the mass of hydrogen to moles by dividing it with
its molar mass. Multiply the moles of hydrogen gas with 2/3 because in the
formation of ammonia you would need 3 mol of hydrogen to form 2 moles of
ammonia. Then multiply the moles of ammonia with the molar mass which is 17.031
grams. The mass of ammonia is 126.48 grams.
Answer:
652.6 g of H₃PO₄ are formed
Explanation:
Reaction is:
P₄O₁₀(s) + 6H₂O(l) → 4H₃PO₄(aq)
As P₄O₁₀ is the reactant in excess, the limiting is water.
Ratio is 6:4. We make a rule of three:
6 moles of water produce 4 moles of phosphoric acid
Therefore, 10 moles of water may prodyce (10 .4) / 6 = 6.66 moles of H₃PO₄
We convert the moles to mass:
6.66 moles . 97.9 g / 1mol = 652.6 g
