Explanation:
1.00 mole of O2 contains 2 × 6.023 × 10²³ atoms
= 12.046 × 10²³
In option A
No of oxygen atoms= 0.667 × 3 × 6.023 × 10²³
= 12.046× 10²³ ✓
In option B
No of oxygen Atoms = 1 × 2 × 6.023 × 10²³
= 12.046 × 10²³ ✓
In option C
No of oxygen atoms= 2 × 6.023 × 10²³
= 12.046 × 10²³ ✓
So option D is correct
Answer:
A
Explanation:
Each lamp has the same resistance of 10 ohms thus the voltage drop will be equal. In a series circuit, the Current, (I) is the same because it does not divide anywhere thus Voltage will vary with resistance.
I think the answer is C) 1/8, I’m sorry if it’s wrong
