How many phosphorus atoms are present ?

For the following reaction, 25.4 grams of sulfur dioxide are allowed to react with 11.6 grams of water . sulfur dioxide(g) water

Answer:

The maximum mass of sulfurous acid that can be formed is 32.54 grams.

Explanation:

The balanced reaction is:

SO₂ + H₂O → H₂SO₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

SO₂: 1 mole
H₂O: 1 mole
H₂SO3: 1 mole

Being the molar masses of each compound:

SO₂: 64 g/mole
H₂O: 18 g/mole
H₂SO₃: 82 g/mole

Then, by stoichiometry the following quantities of mass participate in the reaction:

SO₂: 1 mole* 64 g/mole= 64 g
H₂O: 1 mole* 18 g/mole= 18 g
H₂SO₃: 1 mole* 82 g/mole=82 g

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, you can use a simple rule of three as follows: If 18 grams of water react with 64 grams of sulfur dioxide, how much mass of sulfur dioxide does 11.6 grams of water react with?

$mass of sulfur dioxide=\frac{11.6 grams of water*64 grams of sulfur dioxide}{18 grams of water}$

mass of sulfur dioxide= 41.24 grams

But 41.24 grams of sulfur dioxide are not available, 25.4 grams are available. Since you have less mass than you need to react with 11.6 grams of water, sulfur dioxide will be the limiting reagent.

Then you can apply the following rule of three: if by reaction stoichiometry 64 grams of sulfur dioxide produce 82 grams of sulfurous acid, 25.4 grams of sulfur dioxide, how much mass of sulfurous acid will it produce?

$mass of sulfurous acid=\frac{25.4 grams of sulfur doixide*82 grams of sulfurous acid}{64 grams of sulfur doixide}$

mass of sulfurous acid= 32.54 grams

The maximum mass of sulfurous acid that can be formed is 32.54 grams.

A sample of aluminium has a mass of 54 gram. What is the mass of the same number of magnesium atom.

Arada [10]

Answer:

48g of Magnesium.

Explanation:

We know that:

Mole=given mass/molar mass

Then, moles of aluminum = 54/27 = 2.

A/c to question ,

For 2 moles of magnesium it's mass is 2×24=48g.

Hence, the required mass for same number of magnesium atoms is 48g.

Answer:

the importance of freezing in out daily lives

If you live in Canada you would know why the freezing and melting point of water is important. In the winter when it rises above freezing and rains then drops below freezing again, that water will freeze and cause the roads and sidewalks to be hazardous.

On a recent trip to the US I looked up the weather forecast and it was in Fahrenheit. I couldn't remember exactly what the freezing point of water was in Fahrenheit so I had to look it up. The forecast was for precipitation so I needed to know if it was likely to fall as rain, freezing rain (very dangerous) or snow.

When I use my windshield wipers I need to know that it's not pure water that's being squirted out. In the winter I need to know that there is anti-freeze in it so it won't freeze in the lines.

When I'm hiking up a mountain wearing a Camelback hydration system I need to know if the temperatures will drop below freezing or I will not have any water to drink as the water line will freeze. Same with uninsulated water bottles, and your sandwich.

Explanation:

the importance of evaporation and condensation

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. It soaks up moisture from soil in a garden, as well as the biggest oceans and lakes. The water level will decrease as it is exposed to the heat of the sun.

Although the level of a lake, pool, or glass of water will decrease due to evaporation, the escaped water molecules dont disappear. They stay in the atmosphere, affecting humidity, or the amount of moisture in the air.
