Milk. Everything else is a compound/alloy.
The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
![$\frac{V1}{T1} = \frac{V2}{T2} \\](https://tex.z-dn.net/?f=%24%5Cfrac%7BV1%7D%7BT1%7D%20%3D%20%5Cfrac%7BV2%7D%7BT2%7D%20%5C%5C)
After chilling the drum, the volume will get reduced and it can be found as,
V2 =
= ![$\frac{7.7 L \times 282 K}{598 K}](https://tex.z-dn.net/?f=%24%5Cfrac%7B7.7%20L%20%5Ctimes%20282%20K%7D%7B598%20K%7D)
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.
Answer:
It's a Lithium atom
Explanation:
You can count the red particles in the nucleus, they're the protons. This atom have 3 protons. The atom that have 3 protons is the Lithium atom
Density =mass /volume
Volume =1800÷0.79
= 2278.481ml
<span>Generally negative ions is known as anion and positive ions is known as cation. Anions will gain an electron to fill in an electron shell but cations will lose an electron to fill in an electron shell so that cation by losing the electron the ionic mass will be lower where as for anion by gaining an electron the ionic mass will be higher so that atom will be larger.Therefore negative ions tend to be larger than positive ions.</span>
