no of moles in 4 grams of H2=4/2=2
2H2+O2............2H2O
the reaction shows that 2 moles of H2 react with 1 mole of O2 to produced 2 moles H2O
now no of moles in 36grams of H2O=36/18=2
therefore he needed 1 mole of O2 to produce 36 grams of H2O and 1 mole of oxygen is equal to 32 grams of O2
If it's mechanical then it moves through matter
Explanation:
The two factors that affect the force of gravity are mass and acceleration. Mass is how much matter is in an object.
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
Answer:
true
Explanation: chlorine is an element that exists in nature as a diatomic molecule.
Answer:
0.00446 grams of hydrogen are produced.
Explanation:
Atmospheric pressure at which hydrogen gas was collected = p= 742.1 mmHg
Vapor pressure of the hydrogen gas = p' = 22.4 mmHg
Pressure of the hydrogen gas = P
P = p - p' = 742.1 mmhg - 22.4 mmhg = 719.7 mmHg
719.7 mmHg =
1 atm = 760 mmHg
Volume of the hydrogen gas ,V = 57.48 mL = 0.05748 L
1 mL =0.001 L
Temperature of the hydrogen gas = T = 24°C=24+ 273 K = 297 K
Moles of hydrogen gas = n
( Ideal gas equation)
n = 0.00223 mol
Mass of 0.00223 moles of hydrogen gas:
0.00223 mol × 2 g/mol = 0.00446 g
0.00446 grams of hydrogen are produced.
