Answer:
Magnesium carbonate reacts with hydrochloric acid to produce magnesium chloride, carbon dioxide, and water.
Explanation:
CMgO3 + 2HCl => MgCl2 + CO2 + H20
Hey there!
Potassium has 19 protons.
If this potassium atom has an atomic mass of 41, that means the sum of protons and neutrons is 41.
So, the following must be true:
p + n = 41
p = 19
Which makes this true:
19 + n = 41
Subtract 19 from each side to solve for n, the number of neutrons.
19 - 19 + n = 41 - 19
n = 22
A potassium atom that has an atomic mass of 41 has 22 neutrons.
Hope this helps!
The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.
Answer:
Increasing the Molarity by Volume. Determine the number of moles of solute in a given solution by dividing the number of grams of solute by its molecular mass.
Explanation:
Your answer would be B. Liters
