Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma.

If you have 150 grams of s8, how many moles of so2 can you make?

ruslelena [56]

Answer : You can make 4.68 moles of SO₂

Explanation:

Step 1 : Write balanced equation.

S₈ can combine with oxygen to form SO₂ gas. The balanced equation for this reaction is written below.

$S_{8} + 8 O_{2} \rightarrow 8 SO_{2}$

Step 2 : Find moles of S₈

The formula to calculate mol is

$mole = \frac{grams}{MolarMass}$

Molar mass of S₈ is 256.5 g/mol

$mole = \frac{150grams}{256.5 g/mol}$

$mole = 0.585 mol$

we have 0.585 mol of S₈

Step 3: Use mole ratio to find moles of SO₂

The mole ratio of S₈ and SO₂ can be found using balanced equation which is 1:8

That means 1 mol of S₈ can form 8 moles of SO₂.

Let us use this as a conversion factor to find moles of SO₂

$0.585 mol (S_{8}) \times \frac{8 mol (SO_{2})}{1 mol (S_{8})} = 4.68 mol$

Therefore we have 4.68 moles of SO₂

Why does Al have a larger atomic radius than B

Valentin [98]

Explanation:

While atomic radii DECREASE across a Period, a row of the Period Table, from left to right as we face the Table, atomic radii INCREASE down a Group, a column of the Periodic Table, due to the shielding of the valence electrons by the closed valence shell(s) that intervenes between the nucleus and the valence, outermost electrons.
