Answer:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxcsup
Explanation:
now split the equation in half
CH4+O2 I CO2 + 4H2O
C = 1 I C = 1
H = 4 I H = 8
O = 2 I O = 3
CH4+ 2O2 = CO2 + 2H20
Answer:
Explanation:
number of moles = mass / molar mass
= 525 / 7+14+(3*14)
= 525 / 63
= 8.33 mol
Answer:
0.216
Explanation:
The mole fraction of HCl is the number of moles of HCl (0.99) divided by the total number of moles in the solution.
mole fraction = (0.99)/(0.99 +3.6) = 0.2157
The mole fraction of HCl is about 0.216.
1840 times lesser than
Explanation:
Robert A. Milikan from his experiment found that electrons carry exactly one unit of negative charge and that its mass is 1840 times lesser than the mass of a common hydrogen atom.
- Robert Milikan performed the oil drop experiment and was able to determine the charge on an electron.
- From Milikan's experiment, the relative mass of an electron was discovered to be about 1840 times lesser than the mass of a hydrogen atom.
- A normal hydrogen atom is a proton with an actual mass of 1.67 x 10⁻²⁷kg.
- Electrons weight 9.11 x 10⁻³¹kg which is 1840 less than the weight of a proton.
