Answer: 103.8 g of , 0.65 moles of
Explanation:
To calculate the moles :
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
According to stoichiometry :
3 moles of produce = 2 moles of
Thus 0.975 moles of will produce=
of
Mass of
Thus 103.8 g of will be produced.
Answer:
Explanation:
The unbalanced nuclear equation is
Let's write the question mark as a nuclear symbol.
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
60 = 0 + A, so A = 60 - 0 = 60, and
27 = -1 + Z, so Z = 27 + 1 = 28
Your nuclear equation becomes
Element 28 is nickel, so the balanced nuclear equation is
