Explanation:
When citric acid and baking soda react with one another, they change chemi- cally and form sodium ions, citric acid ions, carbon dioxide gas, and water. ... It also makes up the bubbles in carbonated drinks and is a gas we naturally exhale. Carbon dioxide gas is safe in the quantities produced in the activities.
Answer:
1728 kg is the mass of air for the room
Explanation:
An exercise of unit conversion.
The volume of the room will be:
24 m . 15 m . 4m = 1440 m³
Density of air is 1.20 g/L which means that in 1L, there is contained 1.20 g of air.
1L = 1dm³
1m³ = 1000 dm³
1440 m³ . 1000 = 1440000 dm³ ⇒ 1.44x10⁶ L
Density of air = 1.20 g/L = mass of air / volume of air
1.20 g/L = mass of air / 1.44x10⁶ L
1.20 g/L . 1.44x10⁶ L = mass of air → 1728000 grams
1 g = 1x10⁻³ kg
1728000 g / 1000 = 1728 kg
Answer:
Explanation:
Hello,
In this case, the reaction between sodium and ammonia is:
Thus, as we know the initial masses of both sodium and ammonia, we should first identify the limiting reactant, for which we firstly compute the available moles of sodium:
And the moles of sodium consumed by 21.4 g of ammonia (2:2 mole ratio):
In such a way, since less moles of sodium are available than consumed by ammonia, we can say, sodium is the limiting reactant. Furthermore, the mass of both sodium amide (39 g/mol) and hydrogen gas (2 g/mol) that are produced turn out:
Best regards.
