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 ;)
Hello!
Based on these facts, we should classify Germanium as a Metalloid.
Metalloids are chemical elements with a mixture of properties from metals and non-metals. Although Germanium has a metallic appearance (typical of metals), it doesn't have the conductive properties of metals, but is a semiconductor. The semiconductive properties of Germanium are used in applications like transistors and chips.
Have a nice day!
Answer: The formula of the acid that was neutralized is 
Explanation:
Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate
and bases donate
in water which combine to form water molecules.
As the salt formed is
, the acid must contain
and thus the acid is 
The balanced chemical reaction is ;

The formula of the acid that was neutralized is 
Answer:
C. The law of conservation of matter
