Answer:
![\boxed{\text{300 g}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7B300%20g%7D%7D)
Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
M_r: 32 60
CH₃OH + CO ⟶ CH₃COOH
m/g: 160
(a) Moles of CH₃OH
![\text{Moles of CH$_{3}$OH} = \text{160 g CH$_{3}$OH }\times \dfrac{\text{1 mol CH$_{3}$OH }}{\text{32 g CH$_{3}$OH}}= \text{5.00 mol CH$_{3}$OH}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20CH%24_%7B3%7D%24OH%7D%20%3D%20%5Ctext%7B160%20g%20CH%24_%7B3%7D%24OH%20%7D%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20mol%20CH%24_%7B3%7D%24OH%20%7D%7D%7B%5Ctext%7B32%20g%20CH%24_%7B3%7D%24OH%7D%7D%3D%20%5Ctext%7B5.00%20mol%20CH%24_%7B3%7D%24OH%7D)
(b) Moles of CH₃COOH
![\text{Moles of CH$_{3}$COOH} = \text{5.00 mol CH$_{3}$OH } \times \dfrac{\text{1 mol CH$_{3}$COOH}}{\text{1 mol CH$_{3}$OH }} = \text{5.00 mol CH$_{3}$COOH}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20CH%24_%7B3%7D%24COOH%7D%20%3D%20%5Ctext%7B5.00%20mol%20CH%24_%7B3%7D%24OH%20%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20mol%20CH%24_%7B3%7D%24COOH%7D%7D%7B%5Ctext%7B1%20mol%20CH%24_%7B3%7D%24OH%20%7D%7D%20%3D%20%5Ctext%7B5.00%20mol%20CH%24_%7B3%7D%24COOH%7D)
(c) Mass of CH₃COOH
![\text{Mass of CH$_{3}$COOH} =\text{5.00 mol CH$_{3}$COOH} \times \dfrac{\text{60 g CH$_{3}$COOH}}{\text{1 mol CH$_{3}$COOH}} = \textbf{300 g CH$_{3}$COOH}\\\\\text{The maximum mass of ethanoic acid that can be produced is $\boxed{\textbf{300 g}}$}](https://tex.z-dn.net/?f=%5Ctext%7BMass%20of%20CH%24_%7B3%7D%24COOH%7D%20%3D%5Ctext%7B5.00%20mol%20CH%24_%7B3%7D%24COOH%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B60%20g%20CH%24_%7B3%7D%24COOH%7D%7D%7B%5Ctext%7B1%20mol%20CH%24_%7B3%7D%24COOH%7D%7D%20%3D%20%5Ctextbf%7B300%20g%20CH%24_%7B3%7D%24COOH%7D%5C%5C%5C%5C%5Ctext%7BThe%20maximum%20mass%20of%20ethanoic%20acid%20that%20can%20be%20produced%20is%20%24%5Cboxed%7B%5Ctextbf%7B300%20g%7D%7D%24%7D)
It will take 5.2 years to decay.
The half life of cobalt-60 is 5.2 years. The half life is the time taken for the mass of the substance to decrease by a half.
here, the amount of remaining substance is 50%,
so, ![(\frac{1}{2} )^{n} = 0.5](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B2%7D%20%29%5E%7Bn%7D%20%3D%200.5)
n. log (0.5) = log (0.5)
n = 1
So it would take 1 half lives to decay this much, which is 1 x 5.2 which is 5.2 years.
what do you mean by radioactive decay ?
The process through which an unstable atomic nucleus loses energy via radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A material that has unstable nuclei is considered as radioactive.

Answer:
Option 6 ) Neutralization
Explanation:
For this case, the missing coefficient would be a "6" before the H₂O, within final products (right side of the equiation), hence, the final reaction should be:
2H₃PO₄ + 3Ba(OH)₂ ------> Ba₃(PO₄)₂ + 6H₂O
You should have in mind that the amount of atoms at each side of the chemical equation should be the same, so as to comply with the principle of mass conservation. If you add "6" on the left side of the H₂O, the equation will be balanced (for each side, lef and right, you will have: 12H, 2P, 14O and 3Ba)
Lastly, this is a chemical neutralization reaction, where an acid (H₃PO₄) is reacting with a base (Ba(OH)₂) in order to finally obtain a neutral salt (Ba₃(PO₄)₂) and water (H₂O)
Answer:
If you spill an acid or base on your shoulder immediately wash well with water. Strong bases react with the oils in your shoulder to produce a soapy feeling layer. Rinse until well after that feeling is gone. Do not attempt to neutralize a spill on your skin.
