4. Why do compounds form in nature?

Chemistry
1 answer:
frez [133]3 years ago
3 0

so basically a atom type contains the same number of protons. Chemical bonds put elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds. Elements can't be divided into smaller units not using large amounts of energy.

36.4 g of SnCl2 is dissolved in 135.7 mL of water.
Yuki888 [10]

Answers:

1st: 189.6 g/mol

2nd: 0.1357 L

3rd: 1.41 M

Explanation:

Finding Molar Mass:

SnCl2 = <u>Tin(II) Chloride</u>

Tin has a molar mass of <u>118.71 g/mol</u>

Chloride has a molar mass of <u>35.453 g/mol</u>

Chloride*2 = <u>70.906</u>

<u>118.71 + 70.906 ≈ 189.6 g/mol</u>

Finding Liters of Solution:

L = mL/1000

135.7 mL / 1000 = <u>0.1357</u>

Finding Molarity:

molarity = <u>moles of solute / liters of solution</u>

M = (36.4g /  189.6g) / 0.1357 L = <u>1.41 M</u>

Hope this helped ;)
