Answer:
144 g of H₂O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Next, we shall determine the mass of CH₄ that reacted and the mass of H₂O produced from the balanced equation. This can be obtained as follow:
Molar mass of CH₄ = 12 + (4×1)
= 12 + 4 = 16 g/mol
Mass of CH₄ from the balanced equation = 1 × 16 = 16 g
Molar mass of H₂O = (2×1) + 16
= 2 + 16 = 18 g/mol
Mass of H₂O from the balanced equation = 2 × 18 = 36 g
SUMMARY:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Finally, we shall determine the mass of H₂O produced by the reaction of 64 g of CH₄. This can be obtained as follow:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Therefore, 64 g of CH₄ will react to produce = (64 × 36)/16 = 144 g of H₂O.
Thus, 144 g of H₂O were obtained from the reaction.
Answer:
Species present in the solution after complete reaction: 
Explanation:
First balance the chemical equation,
calculation of mili moles of each:
mili mole of AgNO3= 15mili mole;
mili mole of K2CrO4=10 mili mole;
From balance equation,
2 mili mole of AgNO3 reacts with 1 mili mole of K2CrO4
hence 1 mili mole of AgNO3 reacts with 0.5 mili mole of K2CrO4
15 mili mole of AgNO3 reacts with 7.5 mili mole of K2CrO4
so only 7.5 milimole will be used in the reaction and 2.5 mili mole left in solution.
species present in the solution after complete reaction:
are soluble in water so it will dissociate in the solution
Immiscible is what i think you are looking for
I think the correct answer is decrease in temperature
I feel like that’s the right one
Answer:
Correct answer is (D). as a weak acid it can cross the membrane when in its uncharged form.
Explanation:
Aspirin (acetylsalicylic acid, ASA) is an analgesic and anti-inflammatory agent use in the treatment of gentle to moderate pain, inflammation and fever. It is absorb in the stomach and intestine in an unchanged form.
