B. Beta decay
Beta decay occurs when a high-speed electron is lost from the atom, converting one of the atom's neutrons into a proton. The mass number of the atom then remains the same but its atomic number is increased by one.
This is the decay taking place because the transition from carbon-14 to nitrogen-14 involves an increase in atomic number by 1.

Answer:
The freezing point will be -2.046°C.
Explanation:
The freezing point depression equation is 
Where;
= The temperature depression of the freezing point
= The constant of freezing point depression which is solvent dependent = 1.86°C/m
i = The number of particles the substance decomposes into in solution = 1 for sugar (a covalent compound)
m = The molality of the solution = 1.1
Therefore, we have;
Therefore the freezing point will be 0 - 2.046°C = -2.046°C.

Actually it pretty much still is saturated with salt at the boiling point, which is just a tad over 100C. That's because the solubility curve for NaCl isn't much of curve. It's more of a nearly horizontal line.
Nonetheless, the solubility curve for NaCl does drift upward slightly as T increases, and so by the time the boiling point is reached, it won't be saturated.
Answer:
It is classified as a pure substance
Explanation:
Oxygen is a gas present in the atmosphere in the pure elemental form.
