D. With the same number of protons and different number of neutrons.
Answer:
if balanced reaction then 2 NaOH + MgSO4 → Mg(OH)2 + Na2SO4
Explanation:
The molar mass of the compound potassium nitrate, KNO3 is equal to 101.1032 g/mol. Then, we determine the number of moles present in the given amount,
n = 11.75g / (101.1032 g/mol) = 0.116 mol
Then, molarity is calculated by dividing the number of moles by the volume of the solution. The answer is therefore 0.058 M.
Its C
a catalyst speeds up a reaction by offering the reaction an alternative reaction pathway with a lower activation energy
