Answer:

Sulfur is considered an “impurity” in petroleum. Sulfur in crude oil can corrode metal in the refining process and contribute to air pollution. Petroleum with more than 0.5% sulfur is called “sour,” while petroleum with less than 0.5% sulfur is “sweet.”

How many carbon dioxide (CO2) molecules are produced during the decomposition of 1.25 moles of Carbonic acid (H2CO3)? ****Rememb

Andreas93 [3]

Answer:

7.53×10²³ molecules

Explanation:

Given data:

Number of moles of carbonic acid = 1.25 mol

Number of molecules of CO₂ produced = ?

Solution:

Chemical equation:

H₂CO₃ → CO₂ + H₂O

Now we will compare the number of moles of carbonic acid with CO₂ from balanced chemical equation.

H₂CO₃ : CO₂

1 : 1

1.25 : 1.25

Number of molecules can be determine by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

Number of molecules:

1 mole = 6.022 × 10²³ molecules

1.25 mol × 6.022 × 10²³ molecules / 1 mol

7.53×10²³ molecules

Phosphine, an extremely poisonous and highly reactive gas, will react with oxygen to form tetraphosphorus decaoxide and water. P

pantera1 [17]

Answer:

The mass of P₄O₁₀ (s) formed is 471.03 g

Explanation:

4PH₃(g) + 8O₂(g) → P₄O₁₀ (s) + 6H₂O (g)

This is the ballanced equation.

Every 4 moles of phosphine, 1 mol of tetraphosphorus decaoxide is generated.

Moles of PH₃ = Mass PH₃ / Molar mass PH₃

Moles PH₃ = 225 g / 33.9 g/m

Moles PH₃ = 6.63 moles

So the rule of three, will be:

If 4 moles of PH₃ generate 1 mol P₄O₁₀

Then, 6.63 moles of PH₃ generate (6.63 .1)/4 = 1.66 moles

If we want to know the mass:

Moles . Molar mass = mass

Molar mass P₄O₁₀ = 283.88 g/m

1.66m . 283.88 g/m = 471.03 g

the element cesium forms a with the charge fill in the blank 2 . the symbol for this ion is , and the name is fill in the blank

yulyashka [42]

The element cesium forms a positive ion with the charge +1 . The symbol for this ion is Ce⁺, and the name is cesium ion. The number of electrons in this ion is 54.

<h3>What group does the element cesium belong to in the periodic table?</h3>

Cesium belong to the Group 1A of the periodic table.

Group 1A elements are known as alkali metals.

The alkali metals react with water to form alkalis. They form ions with a positive charge of +1 by the loss of an electron.

In conclusion, cesium is an alkali metals it belongs to group 1A of the periodic table. It forms a positive ion with a charge of +1 by the loss of an electron.
