The underlying purpose of the British building the infrastructure of India was: To rule India more efficiently.

The prefix kilo is the largest of the four prefixes

To find the name of the hydrate, we need to determine the formula of the hydrate by calculating the number of water molecules associated with the anhydrous magnesium carbonate.

First, let's find the mass of water lost during heating:

Mass of water lost = Initial mass - Final mass
Mass of water lost = 15.67 g - 7.58 g
Mass of water lost = 8.09 g

Now, we need to find the molar mass of water (H2O), which is approximately 18.015 g/mol.

Next, we calculate the number of moles of water lost:

Number of moles of water lost = Mass of water lost / Molar mass of water
Number of moles of water lost = 8.09 g / 18.015 g/mol
Number of moles of water lost 0.449 mol

Now, we need to find the number of moles of magnesium carbonate in the anhydrous compound. Since the molar mass of magnesium carbonate (MgCO3) is approximately 84.313 g/mol, we calculate:

Number of moles of magnesium carbonate = Mass of anhydrous compound / Molar mass of magnesium carbonate
Number of moles of magnesium carbonate = 7.58 g / 84.313 g/mol
Number of moles of magnesium carbonate 0.090 mol

Next, we determine the ratio of moles of water to moles of magnesium carbonate:

Ratio of moles of water to moles of magnesium carbonate = (0.449 mol H2O) / (0.090 mol MgCO3)
Ratio of moles of water to moles of magnesium carbonate 5

This ratio indicates that there are 5 moles of water associated with each mole of magnesium carbonate in the hydrate. Therefore, the hydrate is magnesium carbonate pentahydrate, with the chemical formula MgCO3·5H2O.

Thus, the name of the hydrate is magnesium carbonate pentahydrate.

The following prefixes is the largest: Kilo-.
