(Answer) (d) Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not.
Rate of a chemical reaction refers to rate of formation of products from reactions during a chemical reaction. The rates of chemical reactions depend on various factors such as temperature, pressure, concentration of reactants, presence of catalyst etc. For this reason, chemical reaction rates vary with the conditions of the reaction.
Nuclear decay rate refers to the constant ratio of the number of atoms of radioactive nucleus that decay during a certain interval of time to the total number of radioactive atoms at the beginning of the time interval. Nuclear decay rates are constant and do not vary with the conditions of the reaction.

The answer is 155 pm, hope this helps!
PH 1 - 6 = Acids
pH 7 = Neutral
pH 8 - 14 = Bases
An alkaline is a base that is very soluble in water.
Since we know the solution has a ph of 14, it cannot be A, since A is an acid. It can however be B or C. I'd say that the most logical answer would be B, because no testing has been done for other alkaline properties.
The percent by mass of oxygen in carbon dioxide (
) is 72.71%.
<u>Scientific data:</u>
- Molar mass of oxygen gas = 32 g/mol.
- Molar mass of carbon = 12 g/mol.
To calculate the percent by mass of oxygen in carbon dioxide ():
First of all, we would calculate the molar mass of carbon dioxide ();
For the percent by mass of oxygen:
Substituting the parameters into the formula, we have;
Percent mass of oxygen = 72.71%
