How many 600 IU Calcium tabs equals 50000 IU?
50,000/600 = 83 and 1/3
What is calcium carbonate plus sulphuric acid equal to?
They react to give calcium sulfate and water, though the reaction is not very fast because the calcium sulfate is poorly soluble. We sometimes use an equals sign instead of an arrow in a chemical equation but we read it as 'gives' rather than 'equals', because we are not saying the substances are the same thing.
Is the number of protons equals to the number of electrons?
Yes, in an electrically neutral atom or compound or mixture.

What is the sume of positive and negative charges in an ionic compound?
The sum of charges for any ionic bond equals zero. Take the example calcium carbonate - Ca2+CO32-. If you calculate 2+(-2), you get 0 as an answer. This proves that the charges on an ionic compound cancel out, to form an overall neutral substance.
What atomic number of F plus the atomic number of Na equals the atomic number of this element?
Calcium
What is the solid product of calcium chloride plus sodium carbonate equals what plus sodium chloride?
Calcium carbonate.
Calcium plus H2O equals Hydrogen?
Calcium and water react to form calcium hydroxide and hydrogen. Ca + 2H2O --> Ca(OH)2 + H2
