A cleaning bottle contains 83.1 g of ammonia. How many molecules of ammonia are in the bottle?
Tasya [4]

Answer:

2.94 x 10^2^4

Explanation:

First we need to find out how many moles of ammonia there are, using the formula: Mass = mr x moles.

We know the mass is 83.1g, now we need to find the mR of ammonia - NH3.

N = 14, H = 1, so 14 + (3x1) = an mr of 17.

Moles = mass/ mr = 83.1/17 = 4.8882

Now we can multiply the moles by avogadro's constant to find the number of molecules:

4.8882 x (6.02 x 10^2^3 ) = 2.94 x 10^2^4 molecules of ammonia

Answer ASAP 25 points
kykrilka [37]

<u>Answer:</u> The correct answer is NH_3 is the base and NH_4Cl is the salt.

<u>Explanation:</u>

Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce salt and water as products.

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and a base is defined as a substance which accepts protons.

For the given chemical reaction:

NH_3+HCl\rightarrow NH_4Cl

Here, NH_3 is a base because it is accepting proton and HCl is an acid because it is loosing proton.

NH_4Cl is considered as a salt because it is formed by the combination of acid and base.

Hence, the correct answer is NH_3 is the base and NH_4Cl is the salt.
