Answer:

1.13 x 10²⁴formula units

Explanation:

Given parameters:

Number of moles of NH₄Cl = 1.87mol

Unknown:

Number of formula units = ?

Solution:

From mole concept;

     1 mole of a substance contains 6.02 x 10²³ formula units

Now;

    1.87 moles of  NH₄Cl   1.87 x 6.02 x 10²³ = 1.13 x 10²⁴formula units

When nitrogen dioxide (NO2) from car exhaust combines with water in the air, it forms nitric acid (HNO3), which causes acid rain
Gekata [30.6K]

Answer:

n_{HNO_3}=0.584molHNO_3

Explanation:

Hello.

In this case, given the described reaction, the formation of nitric acid turns out:

NO_2+H_2O\rightarrow HNO_3

Since two hydrogen atoms are present at the reactants we balance it as follows:

3NO_2+H_2O\rightarrow 2HNO_3+NO

In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:

n_{HNO_3}=0.292molH_2O*\frac{2molHNO_3}{1molH_2O}\\\\ n_{HNO_3}=0.584molHNO_3

Best regards!

alukav5142 [94]

Answer:

DNA consists of molecules called nucleotides. Each nucleotide comprises a group of phosphates, a group of sugars and a base of nitrogen. The four forms of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The sequence of these bases defines the DNA instructions or genetic code.
