Answer:
6.79 atm
Explanation:
Applying Dalton's law of partial pressure:
, where 
= total partial pressure of all the component gases in the mixture, 
= partial pressure of helium gas, and 
= partial pressure of oxygen gas.
From the illustration, = 7.00 atm and = 0.21 atm. Hence, the partial pressure due to helium is calculated such that:
= 
= 7.00 - 0.21
= 6.79 atm
<em>Therefore, the partial pressure due to helium in order to maintain the pressure due to oxygen at 0.21 atm would be </em><em>6.79 atm.</em>
Answer:
list all the elements.
you need to find a number to multiply both sides to get the same result.
example: I said on the left side: 5×O2 which is 10. on the right side I do the same to get 10.
In order to do this I said: 4×H2O which is 8 H2,and 4 O.
I then said 3×CO2 which gives 3 C and 6 O2. 6+4=10.
Now Oxygen(O) is balanced. Do the same for the rest of the elements.
