For the reaction:
3A +5B--->12C
Here 3 moles of A are reacting with 5 moles of B to produce 12 moles of C.
so, 1 mole of A will produce = 12÷3 moles of C
= 4 moles of C
so 2 moles of A will produce = 4×2 moles of C
= 8 moles of C
so, 2 moles of A are reacting with excess of B to produce 8 moles of C.
so , the answer is 2 moles of A are reacting with excess of B to produce 8 moles of C.
Answer:
Families in chart is offsprings made from molecules
Explanation:
Because babies are made from the offspring on which your eye colors,hair colors and etc.
Chemical is the answer to the question, but nuclear could also be a valid one since it is nearly impossible to reverse that.
Answer:
1.023 J / g°C
Explanation:
Mass, m = 37.9 g
Temperature increase (change) = 25.0°C
Heat = 969 J
Specific heat capacity , c= ?
The relationship between these quantities is given by the equation;
H = mcΔT
c = H / mΔT
c = 969 / (37.9 * 25)
c = 969 / 947.5 = 1.023 J / g°C
