Answer:
Explanation:
Hello,
At first, the answer is wrong, consider the following procedure:
- the pKs, leads to a Ks of:
- now, stating the equilibrium for the calcium sulfate (whereas x is the change during the equilibrium):
- x becomes the concentration of calcium ions and one of the contributions for the total concentration of sulfate ions, thus:
- finally, since the sodium sulfate is totally dissolved, we just simply add its concentration (equal to the sulfate ions yielded by itself) to the outgoing sulfate concentration from the calcium sulfate:

Answer:
Arrow should be yeilds, THE COEFFICIENTS are mole ratios. So every 4 moles of NH3 or ammonia produce 6 moles of H2O water
Answer:
58 g/mol
Explanation:
According to Graham's law, the rate of diffusion of a gas (r) is inversely proportional to the square root of its molar mass (M). Butane's rate of diffusion is 3.8 times slower than that of helium, that is, rButane = rHe/3.8, or rHe/rButane = 3.8. Then,
Answer: bill nye is a og.
The compound (A) is 2-bromo-pentane. See attached picture for the chemical diagram.
Explanation:
2-bromo-pentane (A) reacts with bromine (Br₂) under UV light to form 2,2-dibromopentane and HBr. Also 2-bromo-pentane (A) reacts with NaSH to from pentane-2-thiol, which have an asimetric carbon, and NaBr.
You may find the chemical reactions and diagrams of the compounds in the attached picture.
