Answer:
6
Explanation
every p sublevel holds up to 6 electrons
so the 4p sublevel must hold up to 6 electonsr
Answer:
20 mol
Explanation:
First, balance the chemical reaction
C3H8 + 5O2 --> 4H2O + 3CO2
Using the mole ratio, we can multiply the moles of propane by 4 to find the moles of H2O.
5 × 4= 20
20 mol
Answer:
1,816 L
Explanation:
Molar concentration or molarity is a way to express the concentration of a chemical in terms of moles of substances per liter of solution.
To obtain the liters of this solution you must convert moles/L to g/L with formula weight (FW), thus:
0,1107 mol of KCl / L × (74,6 g / mol) = 8,258 g of KCl / L.
It means that in one liter you have 8,258 g of KCl. Thus, 15,00 g of KCl are contained in:
15,00 g × (1 L / 8,258 g) = 1,816 L

Answer:
7
Explanation:
Given that the total charge is given by;
C =nq
Where;
n = number of charges
q = quantity of charge
Where the total amount of charge is -1.12 x 10-18 C and the magnitude of each charge is -1.602 x 10-19 C
Then the number of electrons is obtained from;
n = -1.12 x 10-18 C/ -1.602 x 10-19 C
n = 7
