Chlorine is diatomic but sodium is not
Answer:
Try using a solid and another type of phase like water and have it at different temperatures. Once you have done that, let them sit in your location that you have them. Make sure to have their starting temperatures and their ending temperatures which should be equilibrium because of the room temperature.

<u>Answer:</u> The density of unknown material is 7.2 g/mL
<u>Explanation:</u>
We are given:
Volume of water already in the container, = 22 mL
Volume of water rise in the cylinder, V = 27 mL
Volume occupied by unknown material =
To calculate density of a substance, we use the equation:
We are given:
Mass of unknown material = 36.0000 g
Volume of unknown material = 5 mL
Putting values in above equation, we get:
Hence, the density of unknown material is 7.2 g/mL
Answer:
7.5 moles of CaBr2 are produced
Explanation:
Based on the equation:
2AlBr3 + 3CaO → Al2O3 + 3CaBr2
<em>2 moles of AlBr3 produce 3 moles of CaBr2 if CaO is in excess.</em>
<em />
Using this ratio: 2 moles AlBr3 / 3 moles CaBr2. 5 moles of AlBr3 produce:
5 moles AlBr3 * (3 moles CaBr2 / 2 moles AlBr3) =
<h3>7.5 moles of CaBr2 are produced</h3>
