If you collect 1.75 L of hydrogen gas during a lab experiment when the room temperature is 23oC and the barometric pressure is 1
1 answer:
Answer:
Explanation:
Hello,
In this case, since we can consider hydrogen gas as an ideal gas, we check the volume-pressure-temperature-mole relationship by using the ideal gas equation:
Whereas we are asked to compute the moles given the temperature in Kelvins, thr pressure in atm and volume in L as shown below:
Best regards.

Answer: 5 moles of can be produced from 5 mol NaHCO3 and 9 mol HCl.
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
1 mole of use 1 mole of
Thus 5 moles of use=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 1 mole of give = 1 mole of
Thus 5 moles of give =
of
5 moles of can be produced from 5 mol
and 9 mol HCl.
