please mark as brainliest!!
Explanation:
ans: gas
The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume . This means the gas is less dense. Density also depends on the material.

C. Alkaline Metal ok thanks
Answer:

Explanation:
Hello there!
In this case, since we need to dilute the 1.75-M HCl, and the total number of moles remain unchanged, we can write:

And in terms of volume and concentration:

Thus, we can solve for the volume of the concentrated HCl as shown below:

Therefore, we plug in the data to get:

Best regards!
The concept that can be used in order to determine the answer to this item is that of ratio and proportion. The ratio of the mass of the product to the sulfuric acid solution used in the first set should be proportional to that of the second. If we let x be the volume of the acid then, the equation that can be used is,
3.2 g / 4 L = 8 g / x L
The value of x from the equation is 10.
<em>ANSWER: 10 L</em>
