Answer:
Explanation:
so u can work out the amount of moles of S8 by using
moles=mass/mr
=16/32.1=0.498moles
then use the molar ratio of
S : Fe
1:1 so the moles of Fe is the same 0.498
The use the equation
mass = mr x moles
=55.8 x 0.498
=27.78
so 27.8 g
hope this make sense :)
Answer: I dont really know
Explanation:
Answer:
The answers to your questions are given below.
Explanation:
1. __H₂ + __O₂ —> __H₂O
The above equation can be balance as follow:
H₂ + O₂ —> H₂O
There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 2 before H₂O as shown below:
H₂ + O₂ —> 2H₂O
There are 2 atoms of H on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before H₂ as shown below:
2H₂ + O₂ —> 2H₂O
Now the equation is balanced.
Elements >>> Reactants >>> Products
H >>>>>>>>> 4 >>>>>>>>>>> 4
O >>>>>>>>> 2 >>>>>>>>>>> 2
2. __ P₄ + __O₂ —> __P₂O₃
The above equation can be balance as follow:
P₄ + O₂ —> P₂O₃
There are 4 atoms of P on the left side and 2 atoms on the right side. It can be balance by writing 2 before P₂O₃ as shown below:
P₄ + O₂ —> 2P₂O₃
There are 2 atoms of O on the left side and a total of 6 atoms on the right side. It can be balance by writing 3 before O₂ as shown below:
P₄ + 3O₂ —> 2P₂O₃
Now, the equation is balanced
Elements >>> Reactants >>> Products
P >>>>>>>>> 4 >>>>>>>>>>> 4
O >>>>>>>>> 6 >>>>>>>>>>> 6
Answer:
<h2>13.64 L</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
From the question we have
From the question we have
We have the final answer as
<h3>13.64 L</h3>
Hope this helps you
M(N)=21.2 g
M(N)=14.007 g/mol
n(N)=m(N)/M(N)
n(N)=21.2g/(14.007g/mol)=1.51 mol
