Answer:
It would take 15 sticks of butter
Explanation:
2 divided by 20 is 0.1
0.1 is how much butter for 1 so now we multiply that by 150
0.1 x 150 = 15
Therefore, you would need 15 sticks of butter for 150 cookies
Answer:
Graham's law states that the rate of effusion or of diffusion of a gas is inversely proportional to the square root of its molecular weight. So, rate of diffusion of hydrogen gas is four times faster than oxygen gas.
Explanation:
Mass of (NH₄)₂U₂O₇ : 410.05 kg
<h3>Further explanation</h3>
Reaction
2UO₂SO₄ + 6NH₃ + 3H₂O → (NH₄)₂U₂O₇ + 2(NH₄)₂SO₄
MW UO₂SO₄ : 366.091
MW (NH₄)₂U₂O₇ : 624.131
MW H₂O : 18.0153
MW NH₃ : 17.0306
mol of 100 kg water :
mol of 100 kg ammonia :
mol of UO₂SO₄ :
Limiting reactants : smallest mol ratio(mol : coefficient)
UO₂SO₄ ⇒ Limiting reactants
mol (NH₄)₂U₂O₇ : mol UO₂SO₄
mass (NH₄)₂U₂O₇
Answer:
A precipate is a solid while an aqueous solution is liquid.
Explanation:
A precipitate is a solid which separates after a chemical reaction occurs. It is the solid product of the reaction.
An aqueous solution is formed when a substance is dissolved in water.
