Answer:
is the first one
is the second one
Explanation:
The roman numeral indicates the charge on the cation (the positively charged ion in the ionic compound, almost always a metal). So manganese (II) acetate tells us there will be a charge of 2+ on the Mg. Gold (I) oxide has a charge of 1+ on the Au.
When a ionic compound is formed, the total charge of the compound (the sum of the postive and negative charges) must equal zero.
Acetate is a polyatomic ion with a charge of 1-. This means there will need to be two of them to balance out the charge on the manganese.
Oxygen, when ionized, has a charge of 2-. This means there will need to be two gold atoms to balance out the negative charges.

<span>Bodies of magma rise in the crust until they reach a point of neutral buoyancy. The expansion of gases brings the magma closer to the surface and drives eruptions. When more gases are dissolve into the magma, there would more chances of explosion. Hope this answers the question.</span>
Now, we're currently in between with almost all the communist/republican countries.
Ever since Donald trump came in president. Things got a bit rough with China and the U.S
There might be a war soon WWIII.
