Answers

The part that is missing from the product side = 6 oxygen atoms.

The equation of photosynthesis

Photosynthesis is the process by which green plants traps in energy from the sun, through their chlorophyll, which they use in the manufacture of sugar with oxygen as a by-product.

The balanced equation of photosynthesis;

6CO2 + 6H2O + (energy) → C6H12O6 + 6O2

From the equation given,

Pure magnesium metal is often found as ribbons and can easily burn in the presence of oxygen. When 3.28 g of magnesium ribbon burns with 7.25 g of oxygen, a bright, white light and a white, powdery product are formed. Enter the balanced chemical equation for this reaction. Be sure to include all physical states. equation: What is the limiting reactant? magnesium oxygen The reaction goes to completion, but in the process of recovering the product, some of it was lost. The the percent yield for the reaction is 83.7%. How many grams of product are recovered? mass of product recovered: g How many grams of the excess reactant remain? Assume the reaction goes to completion. mass of excess reactant: g

Answers

Answer:

2 Mg(s) + O2(g)→ 2 MgO(s)

Explanation:

Number of moles of magnesium reacted = mass/ molar mass = 3.28g/24gmol-1 = 0.137 moles

From the balanced reaction equation;

2 moles of Mg yields 2 moles of MgO

0.137 moles of Mg yields 0.137 moles of MgO

For oxygen;

Number of moles of oxygen reacted = mass/ molar mass = 7.5g/32gmol-1 = 0.234 moles of O2

If 2_moles of oxygen yields 2 moles of MgO

0.234 moles of oxygen yields 0.234 moles of MgO

Hence Mg is the limiting reactant

Theoretical yield of MgO = 0.137 moles × 40 gmol-1 = 5.48 g of MgO

% yield of MgO = 83.7%

But

% yield = actual yield/theoretical yield × 100

actual yield = % yield × theoretical yield / 100

actual yield= 83.7 × 5.48/100

Actual yield = 4.59 g

According to the equation;

2 moles of Mg reacts with 2 moles of oxygen

Hence 0.137 moles of Mg will react with 0.137 moles of O2

Amount of excess reactant = 0.234 moles - 0.137 moles = 0.097 moles

Mass of excess reactant = 0.097 moles × 32gmol-1 = 3.1g of O2

Q. An ingestion tablet contains a mass of 0.30 g of hydroxide [Mg(OH)2] as its only basic ingre magnesium dient. The balanced chemical equation between magnesium and hydrochloric acid (HCl(aq)), the acid produced in the stomach is as follows:
Mg(OH)2(aq) + 2HCl(aq) ⟶ MgCl2(aq) + 2H2O(l)
(i) Calculate the volume of 1.00 M HCl neutralised by two of these ingestion tablets?
(ii) What mass of the salt is formed in this neutralisation reaction?
(iii) How many magnesium ions are present in this amount of a salt?

Answers

(i) The volume of  1.00 M HCl neutralized by two of these ingestion tablets is 20.6 mL

(ii) The mass of salt formed in the neutralization reaction is 0.98 g

(iii) The number of magnesium ions present in that amount of salt is 6.19 × 10²¹ ions

Stoichiometry

(i) From the question, we are to calculate the volume of 1.00 M HCl neutralized two of the ingestion tablets

From the given balanced chemical equation

Mg(OH)₂(aq) + 2HCl(aq) ⟶ MgCl₂(aq) + 2H₂O(l)

This means,

1 mole of Mg(OH)₂ is neutralized by 2 moles of HCl to give 1 mole of MgCl₂

Now, we will determine the number of moles of Mg(OH)₂ present in two of the ingestion tablets

From the given information

Mass of Mg(OH)₂ in 1 ingestion tablet = 0.30 g

∴ Mass of Mg(OH)₂ in 2 ingestion tablets = 0.60 g

Using the formula,

[tex]Number\ of\ moles = \frac{Mass}{Molar\ mass}[/tex]

Molar mass of Mg(OH)₂ = 58.33 g/mol

Then,

Number of moles of Mg(OH)₂ in 2 ingestion tablets = [tex]\frac{0.60}{58.33}[/tex]

Number of moles of Mg(OH)₂ in 2 ingestion tablets = 0.0102863 mole

Now,

If 1 mole of Mg(OH)₂ is neutralized by 2 moles of HCl

Then,

0.0102863 mole of Mg(OH)₂ will be neutralized by 0.0205726 moles of HCl

∴ The number of moles of HCl that would neutralize 2 ingestion tablets is 0.0205726 mole

Now, for the volume of 1.00 M HCl neutralized by two ingestion tablets

Using the formula,

[tex]Volume = \frac{Number\ of\ moles}{Concentration}[/tex]

Volume = [tex]\frac{0.0205726}{1.00}[/tex]

Volume = 0.0205726 L

Volume = 20.5726 mL

Volume ≅ 20.6 mL

Hence, the volume of  1.00 M HCl neutralized by two of these ingestion tablets is 20.6 mL

(ii) For the mass of salt (MgCl₂) formed in the neutralization reaction

Since 1 mole of Mg(OH)₂ is neutralized by 2 moles of HCl to give 1 mole of MgCl₂

Then,

0.0102863 mole of Mg(OH)₂ will be neutralized by 0.0205726 moles of HCl  to give 0.0102863  mole of MgCl₂

∴ The number of moles of the salt (MgCl₂) formed is 0.0102863 mole

For the mass of the salt formed,

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of MgCl₂ = 95.211 g/mol

∴ Mass = 0.0102863 × 95.211

Mass = 0.9793689 g

Mass ≅ 0.98 g

Hence, the mass of salt formed in the neutralization reaction is 0.98 g

(iii) For the number of magnesium ions present in that amount of salt,

1 mole of MgCl₂ contains 1 mole of magnesium ions

Then,

0.0102863 mole of MgCl₂ will contain 0.0102863 mole of magnesium ions

From the formula,

Number of ions = Number of moles × Avogadro's constant

Avogadro's constant = 6.022 × 10²³ mol⁻¹

∴ Number of magnesium ions present = 0.0102863 × 6.022 × 10²³

Number of magnesium ions present = 0.061944 × 10²³

Number of magnesium ions present = 6.1944 × 10²¹

Number of magnesium ions present ≅ 6.19 × 10²¹ ions

Hence, the number of magnesium ions present in that amount of salt is 6.19 × 10²¹ ions

16 m = 9.8 m/s² * t²

One mole of or 392 g of chromium sulphate gives 3 moles of sulphate ions. Thus 30 g of chromium gives 0.15 moles of sulphate ions or 9.39 ×10²² ions.

What are ions?

Ions are charged substances formed by electron lose or gain by an atom. If an atom gain an electron it acquire one unit of  negative charge and if it lose an electron it acquires a positive charge.

The ionization of chromium sulphate is written as follows:

[tex]Cr_{2}(SO_{4})_{3} \rightarrow 2Cr^{3+} + 3SO_{4}^{2-}[/tex]

Hence, one moles of chromium sulphate forms 3 moles of sulphate ions. One mole of chromium sulphate is 392.18 g/mol. Thus number of moles 20.4 g of the compounds is 20.4 / 392.18 = 0.052 moles.

The number of moles of sulphate ions produced by 0.052 moles of chromium sulphate is calculated as follows:

0.052 × 3 = 0.15 moles.

One mole of sulphate ion contains 6.022 × 10 ²³ions. Thus number of ions in 0.15 moles is 0.15 ×6.022 × 10 ²³ =  9.39 ×10²² ions.

How many grams of H2O are produced when 5.38g of O2 is reacted?

Answers

Answer:

2.33 g H20

Explanation:

12.1 grams of water are produced when 5.38g of O₂ is reacted.

What is Mole?

The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.

A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.

Given,

Mass of oxygen = 5.38g

Moles = mass / molar mass

Moles of oxygen = 5.38 / 16

                             = 0.34 moles

From the reaction,                      2H₂ + O₂ = 2 H₂O

1 mole of oxygen gives 2 moles of water.

Thus, 0.34 moles of oxygen will give 2 × 0.34 moles

                                                 = 0.67 moles of water.

Mass of water = moles × molar mass

                    = 0.67 × 18

                    = 12.1 g of water

Therefore, 12.1 grams of water are produced when 5.38g of O₂ is reacted.
