Explanation:
Atomic number of magnesium is 12 and its electronic distribution is 2, 8, 2. On the other hand, atomic number of iodine is 53 and its electronic configuration is ![[Kr]4d^{10}5s^{2}5p^{5}](https://tex.z-dn.net/?f=%5BKr%5D4d%5E%7B10%7D5s%5E%7B2%7D5p%5E%7B5%7D)
.
Hence, there are 7 valence electrons in an iodine atom and there are 2 valence electrons in a magnesium atom.
So, one atom of iodine requires one electron from a donor atom to complete its octet. But one magnesium atom contains two valence electrons.
Therefore, one magnesium atom will combine with two iodine atoms to result in the formation of magnesium iodide as follows.
Therefore, an ionic bond will be formed when magnesium reacts with iodine to make magnesium iodide.
There are so many rock types around! Though, with all the rock types.. there are a few that we study within grade school and such. These types of rocks are,
-Igneous // Igneous rock is formed through the cooling and solidification of magma or lava.
-Sedimentary // Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.
-Metamorphic // The original rock is subjected to heat and pressure, causing profound physical or chemical change.

Molar mass of O2= 16.0 g/mol
molar mass of H2O= 18.0 g/mol
10.0 g of O2= 5 mol
80.0 g of H20= 5 mol
you need twice as the moles of H2 as O2 so there is insufficient H2 and it is the limiting reactant and all of it will react therefore 5.00 moles of H2 with 2.5 mole of O2 to produce 5.00 moles H2O
5.00 moles of H2O is 5.00x18.00=90.00 g
so the answer is 90.00
