allsm [11]

Answer:

The number of atoms in the gemstones of that tiara is 8.9125\times 10^{24} atoms.

Explanation:

Number of diamonds ion tiara = 888

Mass of  each diamond = 1.0 carat = 0.200 g (given)

Mass of 888 diamonds in tiara:

888\times 0.200 g=177.600 g

Given that diamond is a form of carbon.

Atomic mass of  carbon atom = 12 g/mol

Moles of 77.600 g of carbon =\frac{177.600 g}{12 g/mol}=14.800 mol

Number of atoms of carbon 14.800 moles:

14.800 mol\times 6.022\times 10^{23} atoms =8.9125\times 10^{24} atoms

The number of atoms in the gemstones of that tiara is 8.9125\times 10^{24} atoms.

Choose all that apply. As glaciers melted at the end of the last Ice Age:
Kaylis [27]
As glaciers melted at the end of the last Ice Age worldwide sea level increased immensely and river plains were flooded. Glaciers are floating bodies of ice. Ice is frozen water. When glaciers started melting water that had been frozen for decades or centuries was released back into the ocean. That lead to an increase in sea level. This also led to river plains being drowned/flooded. Therefore, the answer is 1 and 2.
