Answer:

D. Two non-metals

Explanation:

Non metals mostly form covalent bonds where they share electrons whereas, metal and nonmetal form ionic bonds where electrons are transferred.

Answer:

1.20 × 10⁻³ mol e⁻

Explanation:

There is some info missing. I think this is the original question.

Suppose a current of 0.880 A flows through a copper wire for 132 seconds. Calculate how many moles of electrons travel through the wire. Be sure your answer has the correct unit symbol and round your answer to significant digits.

Step 1: Given data

Intensity of the current (I): 0.880 A (= 0.880 C/s)

Time elapsed (t): 132 s

Step 2: Calculate the charge, in Coulomb, that travel through the wire

We will find the circulating charge (q) using the following expression.

$q = I \times t = \frac{0.880C}{s} \times 132s = 116C$

Step 3: Calculate the moles of electrons with a charge of 116 C

We will use the relationship 1 mole of electrons = 96,486 C (Faraday's constant)

$116C \times \frac{1mol\ e^{-} }{96,486 C} =1.20 \times 10^{-3} mol\ e^{-}$

Explain why pure water has a very slight electrical conductivity.

Pepsi [2]

For electricity to flow there must be a flow of electrons or ions present in a system or medium. When electricity is passed in pure water, oxygen does not have d-orbitals or f-orbitals through which electrons may pass. In pure water there are no electrolytic substance, so no ions present in the pure water. Therefore electricity can not pass through pure water. Additionally; water cannot dissociate into OH- and H+ when electricity is passed through pure water.
