Answer:
Statement (E) is correct.
Explanation:
Both mass number and atomic mass are integer. Both are unit less.
Atomic mass is approximately equal to mass number of an atom with an unit of daltons or amu or u.
Mass number = number of protons + number of neutrons
So mass number of N = 7 +7 =14
So, atomic mass of n atom = 14 daltons
Hence statement (E) is correct.
Answer:
The answer is C.
Explanation:
because measuring the pH of a substance is a chemical property. The substance must react with the litmus paper to determine its adcidity
<h2>Answer:</h2>
<u>The right choice is </u><u>Adding H2O(g) to the system</u>
<h2>Explanation:</h2>
If we dilute a solution by adding solvent like water, all of the concentrations will decrease and a change in Q occurs. If there are more species in solution that are products than reactants then Q will decrease. Hence the reaction will then shift towards the right side which is product side to reach equilibrium because there will be an increase the concentration of the reactants side,
Reactants are what is consumed in a chemical reaction while products are what is created by the chemical reaction.
