Answer:
Examine the units: If the density is 1 g/mL, how many mL do you need to make 250 g?
X mL * 1 g/mL = 250 g
Solve for X
x mL = 250 g / 1 g/mL = 250 mL

Answer: The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.

When elements combine to form compounds, there are two major types of bonding that can result.
Answer:
For the first one, it's B, C, and D. Hydrothermal vents on the seabed, Underwater volcanoes, and the breaking down of rocks.
Second question is C, Fresh water from the glaciers are melting into it.
Explanation:
For the first answer, I can say that they all relate. Hydrothermal vents on the seabed usually break down rocks with their hot water, same as breaking down rocks and the underwater volcanoes as the broken down rocks they broke escape into the water, therefore making it salty.
Second answer, the glaciers are frozen up ice, almost fresh water. So if they melted and mixed into the <u>salty ocean</u>, the ratio of salt and ocean will be different, as the amount of water will be<em> </em>cleaner.
I don't know the others, for this is how much I could help. Sorry if I didn't answer in time!!
Answer:
56
Explanation:
1 mole of gas at STP occupies 22.4 L of the gas
2.5 mole of the gas at STP occupies 22.4×2.5 L of the gas
so 2.5 mole of the gas at STP occupies 56 L of the gas .
