A chemist prepares a solution of zinc oxalate by measuring out of zinc oxalate into a volumetric flask and filling the flask to
anyanavicka [17]

<u>Answer:</u> The concentration of zinc oxalate is 1.7\times 10^{-11}M

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}

We are given:

Moles of zinc oxalate = 0.0075\mu mol=7.5\times 10^{-9}mol    (Conversion factor:  1mol=10^{6}\mu mol  )

Volume of solution = 450 mL

Putting values in above equation, we get:

\text{Molarity of solution}=\frac{7.5\times 10^{-9}\times 1000}{450mL}\\\\\text{Molarity of solution}=1.66\times 10^{-11}M=1.7\times 10^{-11}M

In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 2.

Hence, the concentration of zinc oxalate is 1.7\times 10^{-11}M

GIVING THE BRAINLIEST
Allushta [10]

The correct answer is A. Charging by friction

Explanation

When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction
