Answer:4.42 g= 1 mol/55.845 =.079 moles of Fe
Explanation:Given 4.42 grams of Fe. The atomic weight of Fe(iron) found on the periodic table is 55.845. Divide grams by the atomic weight to convert to moles.
Answer:
10
Explanation:
The unbalanced combustion reaction is shown below as:-
On the left hand side,
There are 3 hydrogen atoms and 1 nitrogen atom and 2 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side,
must be multiplied by 6 to balance hydrogen.
Left side,
must be multiplied by 4 to balance hydrogen.
Also, Right side,
is multiplied by 4 so to balance nitrogen.
Left side,
must be multiplied by 5 to balance the whole reaction.
Thus, the balanced reaction is:-
Sum of Coefficient of product - 4 + 6 = 10
