the ans is in the picture with the steps
(hope it helps can i plz have brainlist :D hehe)
Explanation:
Aluminum is a substance because it is a metal on the periodic table.It is also known to be a pure substance because it can't be broken down more than it already is. I would definitely check that answer though. XD ~JOLLY~

The balloon will burst if the volume of the balloon is less than 1.68 L since 8 g of sodium bicarbonate produces 1.68 L of carbon dioxide gas.
<h3>What is the volume of carbin dioxude produced from the chemical reaction between sodium bicarbonate (baking soda) and vinegar?</h3>
The volume of carbon dioxide produced is obtained from the equation below:

1 mole of sodium bicarbonate reacts with one mole of acetic acid in vinegar to produce 1 mole of carbon dioxide.
The volume of 1 mole of carbon dioxide is 22.4 L
Moles of sodium bicarbonate in 8 g = mass/molar mass
molar mass of sodium bicarbonate = 106 g
moles of sodium bicarbonate = 8/106 = 0.075 moles
Moles of carbon dioxide produced = 0.075 moles
Volume of carbon dioxide = 0.075 × 22.4 = 1.68 L
Therefore, the balloon will burst if the volume of the balloon is less than 1.68 L.

Answer:
The answer to your question is:
Explanation:
1) Data
mass = 10 g
vol = 20 ml
density = 10/ 20
= 0.5 g/ml
2)
Data
mass = 5 g
density = 2 g/ml
volume = mass / density
= 5 g / 2
= 2.5 g / ml
3)
Data
density = 25 g/ml
volume = 100 ml
mass = 25 x 100
= 2500 g
