Answer:
A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It's about 5.88 trillion miles (9.5 trillion km).

Answer:
Beryllium bromide
Explanation:
There exists 2 elements in the question
Beryllium Be with valence of +2, and it's a metal
Bromine Br with a valence of -1, and is a non - metal.
Both of them combine together forming an ionic bond:
Be + Br(2) -> BeBr(2)
In naming the compound, we would say that since the first is a metal, beryllium, and the second being a halogen, bromine. We name it by calling the first name together with the last name and changing the last name of the non metal from -ine to -ide.
So we have, Beryllium Bromide.
The ratio of (new volume / old volume) is the same as the ratio of (new temperature / old temp).
Just remember that you have to use the ABSOLUTE temperatures.
An absolute temperature is (Celsius + 273).
