Which would be the best to neutralize a large acid spill in your school lab: sodium hydroxide or baking soda? Explain

It is much better to use baking soda. Any acid that reacts with baking soda gives off carbon dioxide. Hence, you can see an endpoint through the fizzing. With this, you will know when to stop adding. If you use NaOH, you might add it to an acid that creates an exothermic reaction. For example, if the acid was sulfuric acid, it will create more heat which will lead to more unfortunate events. To be safe, you add baking soda to neutralize, then mix it with a bit of water.

1. How many molecules of S2 gas are in 756.2 L?

AfilCa [17]

Answer: There are $2.032 \times 10^{25}$ molecules $S_{2}$ gas are in 756.2 L.

Explanation:

It is known that 1 mole of any gas equals 22.4 L at STP. Hence, number of moles present in 756.2 L are calculated as follows.

$Mole = \frac{Volume}{22.4 L}\\= \frac{756.2 L}{22.4 L}\\= 33.76 mol$

According to mole concept, 1 mole of every substance contains $6.022 \times 10^{23}$ molecules.

Therefore, molecules of S present in 33.76 moles are calculated as follows.

$1 mol = 6.022 \times 10^{23}\\33.76 mol = 33.76 \times 6.022 \times 10^{23}\\= 2.032 \times 10^{25}$

Thus, we can conclude that there are $2.032 \times 10^{25}$ molecules $S_{2}$ gas are in 756.2 L.

By definition, a solution containing a large number of hydroxide ions is best defined as _________.

Kitty [74]

My guess is on B since Hydroxide ions are OH- which is a basic ion not an acid (which can be symbolized by H+) and not D since its a theory that certain ions are acids.<span />
