Chemistry
1 answer:
amm18123 years ago
6 0

Answer:

8moles

Explanation:

We are given the mass of ammonia to be 136g

  Ammonia = NH₃  

Let us find the number of moles in ammonia;

 Number of moles  = \frac{mass}{molar mass}  

  Molar mass of ammonia = 14 + 3(1) = 17g/mol

so;

   Number of moles  = \frac{136}{17}   = 8moles

larisa86 [58]

Answer:

0.234 M

Explanation:

C- 12.009 x 7

H- 1.001 x 5

N- 14.006

O- 16 x 3

S- 32.059

___________+

183.133 g/mol

\frac{1mol}{183.133g} *\frac{85.6g}{2.00L}  = 0.234 M Cancel out the grams mol/L equals molarity. Lowest significant figure is 3

Choose the weaker acid in each of the following pairs:H₂SO₃ or H₂SO₄
WINSTONCH [101]

H₂SO₃ is weaker acid than  H₂SO₄.

The bonding power of an acid is typically influenced by the size of the "SO₄" atom; the smaller the "SO₄" atom, the stronger the H-A bond. The atoms get larger and the bonds get weaker as you proceed down a row in the Periodic Table, strengthening the acids.

<h3>Describe acid.</h3>

The term "acid" refers to any molecule or ion that can donate a proton (a Brnsted-Lowry acid) or establish a covalent bond with an electron pair (a Lewis acid). The first class of acids is the proton donors, also known as Brnsted-Lowry acids.

Its chemical name is lysergic acid diethylamide, or LSD as it is more often known. Because it has a potent hallucinogenic impact, using it could alter how you see the world and its objects. The effects of LSD are referred to as tripping.

The term "acid" is frequently used to denote aqueous solutions of acids with a pH lower than 8, even though the technical meaning of the term only pertains to the solute.
