<u>Answer:</u> The density of NaCl solution is 3.930 g/mL
<u>Explanation:</u>
We are given:
Mass of cylinder,
= 21.577 g
Mass of NaCl and cylinder combined, M = 39.664 g
Mass of NaCl,
= 
To calculate density of a substance, we use the equation:

We are given:
Mass of NaCl = 18.087 g
Volume of NaCl solution = 4.602 mL
Putting values in above equation, we get:

Hence, the density of NaCl solution is 3.930 g/mL
Answer:
<u>(A) Plants would probably not have enough nitrogen.</u>
Explanation:
<em>According to the passage, bacteria help us digest our food and make yogurt. But it is the bacteria in the soil specifically that "Cycle nitrogen through the ecosystem, which plants rely on"</em>
Without plastic, we wouldn't have as much of an environmental problem as we have now. Even though plastic has a lot of negatives, it's also made our lives a lot easier over past years. ... Our cars would have been different since a lot of the materials used inside are made out of plastic.

The mass of water produced by the reaction of the 23 g of
is 13.8 g.
The given chemical reaction;

In the given compound above, we can deduce the following;
- molecular mass of
= 28 + (2 x 16) = 60 g - molecular mass of
= 2(18) = 36 g
60 g of
--------- 36 g of water
23 g of
------------- ? of water

Thus, the mass of water produced by the reaction of the 23 g of
is 13.8 g.
