Callie rode her bike from the tree at point A back to her house to pick up her jacket while Sue road her bike directly from the
Serjik [45]

B

We can perceive this question as a vector (which has both magnitude and direction). The magnitude is the displacement and the direction is where they are headed.

Explanation:

The displacement (magnitude of the vector) for Callie, which is also equal to the distance, is; 4m + 3m = 7m while that of Sue is 5m. Therefore the displacement for Callie is greater than Sue’s.

Nonetheless the direction in the vector is the same, which is towards point C.

How many atoms of Lead are in a 62.7 g sample of Lead(II) permanganate?
Alexandra [31]

Answer:

\large \boxed {8.48 \times 10^{22}\text{ atoms}}

Explanation:

1 mol of Pb(MnO₄)₂contains 1 mol of Pb atoms.

1. Moles of Pb

\text{Moles of Pb} = \text{62.7 g Pb(MnO$_{4}$)}_{2} \times \dfrac{\text{1 mol Pb(MnO$_{4}$)}_{2}}{\text{445.07 g Pb(MnO$_{4}$)}_{2}}\\\\\times \dfrac{\text{1 mol Pb}}{\text{1 mol  Pb(MnO$_{4}$)}_{2}} = \text{0.1409 mol Pb}

2. Atoms of Pb

\text{Atoms of Pb} = \text{0.1409 mol Pb } \times \dfrac{ 6.022  \times 10^{23}\text{ atoms Pb }}{\text{1 mol Pb }}\\\\= \large \boxed {\mathbf{8.48 \times 10^{22}}\textbf{ atoms Pb }}
