Answer:
The limiting reactant is B.
Explanation:
The equation for the reaction is given below:
2A + 3B —> C + D
The limiting reactant can be obtained as follow:
From the equation above,
2 units of A reacted with 3 units of B.
Therefore, 5 units of A will react with = (5 x 3) /2 = 7.5 units of B.
From the calculation made above, we can see that it will take a higher unit of B i.e 7.5 units than what was given i.e 6 units to react completely with 5 units of A.
Therefore, B is the limiting reactant and A is the excess reactant.
Answer:
652.6 g of H₃PO₄ are formed
Explanation:
Reaction is:
P₄O₁₀(s) + 6H₂O(l) → 4H₃PO₄(aq)
As P₄O₁₀ is the reactant in excess, the limiting is water.
Ratio is 6:4. We make a rule of three:
6 moles of water produce 4 moles of phosphoric acid
Therefore, 10 moles of water may prodyce (10 .4) / 6 = 6.66 moles of H₃PO₄
We convert the moles to mass:
6.66 moles . 97.9 g / 1mol = 652.6 g
Answer:
the Answer is B because that what I know
Length=The distance between two points
Mass=The amount of matter contained in a body
Time=The interval or duration between two events
Temperature=The hotness and coldness of a body
