Compare the arrangements of individual particles in solids, liquids, and gases

1 answer:

4 0

Solids - particles are very close together (highest density on the list)
Liquids - the particles slide past one another
Gases - particles bounce off of surroundings and the same particles of the gas

B. How many moles of phosphorous pentachloride will react with 7.36 g of water?

Flura [38]

Answer:

0.102 mol

Explanation:

Step 1: Write the balanced equation

PCl₅ + 4 H₂O ⇒ 5 HCl + H₃PO₄

Step 2: Calculate the moles corresponding to 7.36 g of H₂O

The molar mass of H₂O is 18.02 g/mol.

7.36 g × 1 mol/18.02 g = 0.408 mol

Step 3: Calculate the moles of PCl₅ required to react with 0.408 moles of H₂O

The molar ratio of PCl₅ to H₂O is 1:4.

0.408 mol H₂O × 1 mol PCl₅/4 mol H₂O = 0.102 mol PCl₅

In the manufacture of steel, pure oxygen is blown through molten iron to remove some of the carbon impurity. if the combustion o

Schach [20]

In the extraction process of steel, one of the step is purification of the iron used to make the steel. In which pure oxygen is blown on the steel at high temperature so that the carbon percentage present in the steel can be thrown out in the form of gas. The process occurs at high temperature which is called combustion process. The reaction occurs can be shown as- C(s)+ $O_{2}$ →C $O_{2}$ (g) + CO (g). In presence of excess oxygen, the produced carbon mono oxide (CO) converts to carbon di-oxide. The reaction is CO(g) + $O_{2}$ (g) → C $O_{2}$ (g). From the density of the evolved gas one could identify the gas. If the gas density is 1.77g/L which is very close to the standard density of C $O_{2}$ i.e. 1.80g/L, the gas is carbon dioxide only.
