Question

MgCL2+HNO3=??????????????

Answer 1

MgCL2+2HNO3=Mg(NO3)2+2HCL

Answer 2

The user's message is in Russian and it translates to "Answer in detail. MgCL2 HNO3=??????????????". The user is asking for the balanced chemical equation of the reaction between magnesium chloride (MgCl2) and nitric acid (HNO3).

According to one of the web search results, the balanced chemical equation is:

MgCl2 + 2HNO3 = Mg(NO3)2 + 2HCl

This is a double displacement (metathesis) reaction, where the cations and anions of two compounds exchange places and form new compounds. In this case, magnesium (Mg2+) and hydrogen (H+) swap places, forming magnesium nitrate (Mg(NO3)2) and hydrogen chloride (HCl).

To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. We can do this by using coefficients (numbers in front of the compounds) to adjust the number of molecules. For example, we can see that there are two nitrate (NO3-) ions on the right side, but only one on the left side. To balance this, we need to put a coefficient of 2 in front of HNO3 on the left side. This also balances the number of hydrogen atoms, since there are now four on each side. However, this also changes the number of chlorine atoms, since there are now two on the right side, but only one on the left side. To balance this, we need to put a coefficient of 2 in front of HCl on the right side. This also balances the number of chlorine atoms, since there are now two on each side. Now, the equation is balanced, since the number of atoms of each element is the same on both sides.
