Answer:
71%
Explanation:
Theoretical Yield = 24
Actual Yield = 17
(Actual Yield/Theoretical Yield)*100% = (17/24)*100% ≈ 71%
Answer: <span>b. 34.5 g/kg

The average salinity of the ocean would be 3.45% or 35 parts per millions(ppm). That means 3.45% of the ocean water weight would be contributed by salt. Water density is 1kg/liter or 1000g/1000ml.
Then, 3.45% of it would be: 3.45% * 1000= 34.5g/kg or 34.5g/l
Answer:
6 mass
Explanation:
because the si unit of gram is mass
The answer is c) Electrical energy
Answer:
Answer is: Keq = [CO₂].
Explanation:
Balanced chemical reaction: CaCO3(s) ⇄ CaO(s) + CO₂(g).
The equilibrium constant (Keq) is a ratio of the concentration of the products to the concentration of the reactants.
Pure liquids (shown in chemical reactions by appending (l) to the chemical formula) and solids (shown in chemical equations by appending (s) to the chemical formula) not go in to he equilibrium constant expression, only gas state (shown in chemical reactions by appending (g) to the chemical formula) reactants and products go in to the equilibrium constant expression
