Comets are usually made up of dust and ice. They grow "tails" when they come close to the sun. A nucleus is what comment have in common. These nucleus are usually ice or a rock. 
Meteors are what we usually call shooting stars. They are these white and short trails that decorates the night sky during meteor showers. These trails are caused when they meteors burn up when they come close to the Earth's atmosphere at very fast velocities.

According to the following reaction, how many grams of sulfur are formed when 37.4 g of water are formed?
julia-pushkina [17]

Answer:

Mass = 100.8 g

Explanation:

Given data:

Mass of sulfur formed = ?

Mass of water formed = 37.4 g

Solution:

Chemical equation:

2H₂S + SO₂      →   3S + 2H₂O

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 37.4 g/ 18 g/mol

Number of moles = 2.1 mol

Now we will compare the moles of water and sulfur.

          H₂O         :            S

            2             :          3

           2.1            :         3/2×2.1 = 3.15

Mass of sulfur:

Mass = number of moles × molar mass

Mass = 3.15 mol × 32 g/mol

Mass = 100.8 g
