Answer is: <span>the percent yield is 56.85%.
</span>Chemical reaction: CH₄ + 2O₂ → CO₂ + 2H₂O.
m(CH₄) = 987 g.
n(CH₄) = m(CH₄) ÷ M(CH₄).
n(CH₄) = 987 g ÷ 16 g/mol.
n(CH₄) = 61,68 mol.
From reaction: n(CH₄) : n(CO₂) = 1 : 1.
n(CO₂) = 61,68 mol.
m(CO₂) = 61,68 mol · 44 g/mol.
m(CO₂) = 2714,25 g ÷ 1000 g/kg = 2,714 kg.
yield = 1,543 kg ÷ 2,714 kg · 100 % = 56,85%.
The correct answer to this question is Water will move from left to right.
Water tends to move over to the side where there is less water.
For example,
if there's less water on the RIGHT side,
then the water will tend to move from left, to RIGHT. It <span>shows more solute molecules on the right, so water will move to this side by osmosis. I think it is to do with entropy and the tendency for systems to move to equilibrium if there is an increase in entropy</span>
Answer:
A. Convex lens.
Explanation:
A convex lens causes light rays to meet at a focal point unlike concave, which lights rays spread out.
The ones on left are the reactants
Water can only dissolve inorganic compounds is false
