zlopas [31]

The number of H atoms in 3(NH₄)₂CrO₄ = 24

<h3>Further explanation  </h3>

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula  

Subscripts in the chemical formula indicate the number of atoms

The compound of 3(NH₄)₂CrO₄ ( 3 molecules of (NH₄)₂CrO₄ ) :

Number of H :

\tt 4\times 2(subscript)\times 3(coefficient,number~of~molecules)=24~atoms

Is 2Na+Cl2=2NaCl a balanced chemical equation
lilavasa [31]

Hey there!

2Na + Cl₂ → 2NaCl

This is a balanced chemical equation.

There are 2 atoms of sodium (Na) on the left, and 2 atoms of sodium (Na) on the right.

There are 2 atoms of chlorine (Cl) on the left, and 2 atoms of chlorine (Cl) on the right.

This means the equation is balanced since there are the same amount of each element on both sides.

Hope this helps!

What is the mass of snow (in tons) on a 150.0ft by 45.0 ft flat roof after a 6.0 inch snowfall? Assume that 11 inches of snow is
Aneli [31]
6 inches of snowfall would be equivalent to 6/11 inches of water or 6/132 feet. So the volume of the equivalent amount of water on the roof is 150 ft. x 45 ft. x 6/132ft. = 306.8 cubic feet.   
Since there are 907185 grams in a ton and 28316.8 mL in a cubic foot, 1.00 g/mL is equivalent to 0.0312 tons/cubic foot  
Multiplying the two results gives 9.58 tons of snow.
