Answer:
% yield = 82.5%
Explanation:
HgO + 2Cl₂ → HgCl₂ + Cl₂O
Our reactants are:
Our products are:
We do not have information about moles of reactants, but we do know the theoretical yield and the grams of product, in this case Cl₂O, we have produced.
Percent yield = (Yield produced / Theoretical yield) . 100
Theoretical yield is the mass of product which is produced by sufficent reactant. We replace data:
% yield = (0.71 g/0.86g) . 100 = 82.5%
The correct answer is A. All electrons become free and separate from the nuclei. In metallic bonds, the electrons of the metal atoms are delocalized. The electron in the electron sea can freely roam around or are free to flow.
The right answer is Radiant energy is converted to stored chemical energy.
Photosynthesis aims to create energy (in the form of carbohydrate) from the light energy from the sun.
Solar energy is used to oxidize water and reduce carbon dioxide to synthesize organic substances (carbohydrates). This phenomenon occurs in chloroplasts, a plant-specific organelle, at the level of the thylakoid membranes where photosystems I and II and cytochromes are located.
False. gases have to greatest freedom of motion
