Answer:
The volume of hydrogen gas produced at STP is 4.90 liters.
Explanation:
Moles of aluminium =
According to reaction , 2 moles of aluminium gives 3 moles of hydrogen gas.
Then 0.1333 moles of aluminium will give:
of hydrogen gas
Volume of 0.2 moles of hydrogen gas at STP = V
Temperature at STP = T = 298.15 K
Pressure at STP = P = 1 atm
n = 0.2 mol
PV = nRT (Ideal gas equation)
The volume of hydrogen gas produced at STP is 4.90 liters.
If the solution is BASIC than it will turn purple but if ACIDIC it will turn pink.

I need more information... what was the experiment??
Answer:
Mass is the measure of the amount of matter in an object. We see that the gravitational force between objects increases as the masses of the objects increase. With distance, we see that the strength of gravity decreases if the distance between two objects increases.
Explanation:
The amount of gravity affecting an object depends on two things: the masses of the objects being attracted and the distance between the objects. Mass is the measure of the amount of matter in an object. ... With distance, we see that the strength of gravity decreases if the distance between two objects increases
