SpyIntel [72]

Answer: The correct answer is 0.745 km

Explanation:

We are given:

A numerical value of 815 yards

To convert this into kilometers, we use the conversion factor:

1 km = 1093.6 yards

Converting the given value into kilometers, we get:

$\Rightarrow 815yd\times \frac{1km}{1093.6yd}=0.745km$

Hence, the correct answer is 0.745 km

The nitrate anion is Select one: a. a strong acid. b. a strong base. c. amphoteric. d. a strong reducing agent. e. a strong oxid

svp [43]

Answer: Option (e) is the correct answer.

Explanation:

Chemical formula of a nitrate ion is $NO^{-}_{3}$ and it acts as a strong oxidizing agent because it itself gets reduced easily.

As we know that an oxidizing agent tends to oxidize other substances by itself gaining electrons. As a result, there will occur a decrease in its oxidation state.

The oxidation number of nitrogen in $NO^{-}_{3}$ is +5. So, it gains electrons and helps in oxidizing other substances.

Thus, we can conclude that the nitrate anion is a strong oxidizing agent.
