Do different types of magnesium react with calcium differently?

When you mean different type of magnesium, it can either be isotopes of magnesium or magnesium compounds. If you mean isotopes, i doubt any isotopes of magnesium is able to react with its calcium brethren. If you're talking bout magnesium compounds, reactivity between the metals depends on the electrochemical series, since magnesium is more electronegative, therefore i dont think calcium is able to displace magnesium from its compound. but magnesium is able to displace calcium from its compound.


What compound is made from calcium and bromine?

Is magnesium acetate a calcium compound?

No. In order to be a calcium compound, it must have calcium in it. Magnesium Acetate is made up of magnesium, carbon, hydrogen and oxygen atoms. Acetate is an ion with the chemical formula, C2H2O2 (technically CH2COO- due to the fact that it's a carboxylate), two carbon, two hydrogen and two oxygen atoms. So no, there is no calcium atoms present.
