Given: 1 mole of methane (\( \text{CH}_4 \))
Electron count per molecule:
Avogadro's number: \( 6.023 \times 10^{23} \) molecules/mole
Total electrons: \[ 10 \times 6.023 \times 10^{23} = 60.23 \times 10^{23} \]
Thus, the correct option is (B): \( 60.23 \times 10^{23} \).
Choose the correct option
Molecule | Shape | ||
---|---|---|---|
A | \(BrF_5\) | i | T-shape |
B | \(H_2O\) | ii | See-saw |
C | \(ClF_3\) | iii | Bent |
D | \(SF_4\) | iv | Square Pyramidal |
For the reaction:
\[ 2A + B \rightarrow 2C + D \]
The following kinetic data were obtained for three different experiments performed at the same temperature:
\[ \begin{array}{|c|c|c|c|} \hline \text{Experiment} & [A]_0 \, (\text{M}) & [B]_0 \, (\text{M}) & \text{Initial rate} \, (\text{M/s}) \\ \hline I & 0.10 & 0.10 & 0.10 \\ II & 0.20 & 0.10 & 0.40 \\ III & 0.20 & 0.20 & 0.40 \\ \hline \end{array} \]
The total order and order in [B] for the reaction are respectively:
