Answer:
Explanation:
CH4 + 2O2 --> CO2 + 2H2O
1mol generates 2 moles of H2O
Therefore 6 Moles produce 12 moles of H2O
The phase's composition is as follows: 27
What is the alloy's composition?
Both have mass fractions of w a = w b = 0.5.
A-B alloy composition; C o = 57 wt% B - 43 wt% A
C b = 87 wt% B - 13 wt% A is the new phase composition.
Using the Lever rule, we can calculate the mole fraction (x i) or mass fraction (w i) of each phase of a binary equilibrium phase as follows:
W a = W b = 0.5
This provides us with;
0.5 = (C b - C o)/(C b - C a)
(87 - 57)/(87 - C a) = 0.5
30/0.5 = 87 - C a
60 = 87 - C a
C a = 87 - 60
C a = 27

Moving the electron away from the nucleus requires energy, so the electrons in the outer shell will have more energy than ones in the inner shell. Electrons always have a charge of -1, so the charge in the inner and outer shell will be the same. Therefore the answer is 3
Answer:
Scale Factor: 1 : 2
X = 11
Explanation:
3 / 3 = 1
6 / 3 = 2
The scale factor should be 1:2
So 'X' should be 11 since 5.5 * 2 = 11
