They are two representatives of the sublevels/energy levels.
Answer:
Explanation:
Charles law states that "the volume of a fixed mass of gas varies directly as its absolute temperature if the pressure is constant".
This law is a derivative of the kinetic molecular theory of gases.
- The law explained shows that as the temperature of gases increases the volume of gases increases.
- When gases are heated the average kinetic energy of the molecules increases.
- The molecules are independent of one another and they begin to expand out as their velocity surges.
- They take up more spaces in this way.
Answer:
8.55 moles
Explanation:
The formula for calculating molarity is moles of solute divided by liters of solution. In this case:
moles. Hope this helps!
Answer:
Please see the complete formt of the question below
Chlorine gas can be made from the reaction of manganese dioxide with hydrochloric acid.
MnO₂(s) + HCl(aq) → MnCl₂(aq) + H₂O(l) + Cl₂(g)
According to the above reaction, determine the limiting reactant when 5.6 moles of MnO₂ are reacted with 7.5 moles of HCl.
The answer to the above question is
The limiting reactant is the MnO₂
Explanation:
To solve this, we note that one mole of MnO₂ reacts with one mole of HCl to produce one mole of MnCl₂, one mole of H₂O and one mole of Cl₂
Molar mass of MnO₂ = 86.9368 g/mol
Molar mass of HCl = 36.46 g/mol
From the stoichiometry of the reaction, 5.6 moles of MnO₂ will react with 5.6 moles of HCl to produce 5.6 moles of H₂O and 5.6 moles of Cl₂
However there are 7.5 moles of HCL therefore there will be an extra 7.5-5.6 or 1.9 moles of HCl remaining when the reaction is completed
