Answer:

4.13 x 10^{2} = 413 kg

Explanation:

4.13 x 10 = 41.3 then we multiply 41.3 by 10 agian = 41.3 x 10 = 413

so, we multiplied ten two times that = 10^{2}

= 4.13 x 10^{2}= 413 kg

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 ;)

Which of the following is not a true statement? a. oxiranes are three-membered ring ethers. b. oxetanes are five-membered ring e
AURORKA [14]

The true statement will be "oxetanes are <u>five-membered ring</u><u> </u><u>ethers."</u>

The four-membered ring of octane, a saturated organic heteromonocyclic parent, contains three carbon atoms but one oxygen atom. It belongs to the family of oxetanes well and has a saturated organic heteromonocyclic parent.

Oxetanes can also be widely employed as monomers inside the cationic or anionic synthesis including both branched but also linear poly-ethers. Thermal decomposition, photolysis, as well as cycloaddition are further beneficial reactions.

The structure of oxetanes are shown as:

The Patern-Büchi reaction is another process that could result in the formation of an oxetane ring. In addition to decarboxylation of such a six-membered cyclic carbonate, diol cyclization can also create the oxetane ring.

a)Oxiranes has two carbon ring with one oxygen.

b) Oxetanes has 3 carbon ring with one oxygen

c) Dioxanes has six membered ring with two oxygen.

Therefore, the true statement will be "oxetanes are five-membered ring ethers."

Hence, the correct answer will be option (b)
