Answer:
144 g of H₂O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Next, we shall determine the mass of CH₄ that reacted and the mass of H₂O produced from the balanced equation. This can be obtained as follow:
Molar mass of CH₄ = 12 + (4×1)
= 12 + 4 = 16 g/mol
Mass of CH₄ from the balanced equation = 1 × 16 = 16 g
Molar mass of H₂O = (2×1) + 16
= 2 + 16 = 18 g/mol
Mass of H₂O from the balanced equation = 2 × 18 = 36 g
SUMMARY:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Finally, we shall determine the mass of H₂O produced by the reaction of 64 g of CH₄. This can be obtained as follow:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Therefore, 64 g of CH₄ will react to produce = (64 × 36)/16 = 144 g of H₂O.
Thus, 144 g of H₂O were obtained from the reaction.

The nervous system.

The answer is 0.365:100.
v/c ratio represents ratio of speed of an electron (v) to the speed of light (c).
How is the speed of an electron calculated?
- The speed of an electron (v) is given by Bohr's model as-
Now, for the first excited state, n = 2.
e - Charge of electron = 
×
C
h - Plank's constant = 
×
ε₀- permittivity 
×
- Put the above data in the formula-
- Now, the speed of light, c =
×
- Thus, the v/c ratio for an electron in the first excited state is calculated as-
= 
- Hence, the v/c ratio = 0.365:100.
