Sunlight is converted to electricity in a photovoltaic cell.

Things like cloths washer and dryer heating hot water for the bath, powering the oven, and of course lighting in the home can all be run with solar power. There are even solar power pool heater band air conditioners. Today, photovoltaics is probably the most familiar way to harness solar energy. Photovoltaic arrays usually involve solar panels, a collection of dozens or even hundreds of solar cells.

Each solar cell contains a semiconductor, usually made of silicone. When the semiconductor absorbs sunlight, it knocks electronics loose.

:) I hope this helps

Find the mass of oxygen in grams produced by the decomposition of 100.0 g of CO2

SSSSS [86.1K]

The balanced chemical equation is :

$2CO_2->2CO+O_2\\\\$

Moles of $CO_2$ ,

$n = \dfrac{100\ g}{44.01\ g/mol}\\\\n=2.27\ mol$

Now, by given chemical equation , we can see 2 mole of $CO_2$ react with 1 mole of $O_2$ .

So , 2.27 mole react with :

$N=\dfrac{2.27}{2}\ mol\\\\N=1.135\ mol$

Mass of oxygen is :

$M = N \times 16\\\\M=1.135\times 16\ g\\\\M =18.16\ g$

Therefore, mass of oxygen in grams produced is 18.16 g.

Hence, this is the required solution.

If 50.75 g of a gas occupies 10.0 L at STP, 129.3 g of the gas will occupy __________ L at STP.

Vlad [161]

If 50.75 g of a gas occupies 10.0 L at STP, 129.3 g of the gas will occupy 25.48 L at STP.

<h3>How to calculate volume?</h3>

The volume of a gas at STP can be calculated using the direct proportion method.

According to this question, 50.75 g of a gas occupies 10.0 L at STP, then 129.3g of the same gas will occupy the following:

= 129.3 × 10/50.75

= 25.48L

Therefore, if 50.75 g of a gas occupies 10.0 L at STP, 129.3 g of the gas will occupy 25.48 L at STP.
