Explain how oxygen and carbon dioxide move with breathing.

Answers

Answer 1

Answer/Explanation:

With oxygen, it is what you breathe in so obviously, it is going to move around into your body. But with carbon dioxide, it is what you breathe out. When you breathe in, your body takes in the oxygen and the releases the carbon dioxide. Carbon dioxide is what plants actually consume, while they release oxygen.

Answers

Answer:

Hydrocarbons are insoluble in water because they are non-polar compounds while water is a polar solvent. By principle, like dissolves like. Nonpolar solvents dissolve nonpolar solutes and polar solvents dissolve polar solutes.

Explanation:

Hydrocarbons are insoluble in water because :-

1)Hydrocarbons are nonpolar whereas water is polar. (like dissolves like).

2) Hydrocarbons and water do not exhibit appropriate solvent-solute interactions. Hydrocarbons only form very weak dispersion forces whereas water produces strong polar hydrogen bonding interactions.

If 22.00 mL of 2.00 M potassium iodide is needed to reach the equivalence point with 18.00 mL of lead (II) nitrate, determine the molarity of the lead (II) nitrate solution. Note: First write the balance equation between potassium iodide and lead (II) nitrate.

Answers

The molarity of the lead(II) nitrate solution if 22.00 mL of 2.00 M potassium iodide is needed to reach the equivalence point with 18.00 mL of lead (II) nitrate is 1.2M.

How to calculate molarity?

The molarity of a solution can be calculated using the following formula:

CaVa/CbVb = na/nb

Where;

Ca = concentration of acidCb = concentration of baseVa = volume of acidVb = volume of basena = number of moles of acidnb = number of moles of base

The balanced equation of the reaction is as follows:

Pb(NO3)2 (aq) + 2KI (aq) → 2KNO3 (aq) + PbI2 (s)

22 × 2/18 × Cb = 2/1

44/18Cb = 2

Cb = 44 ÷ 36

Cb = 1.2M

Therefore, the molarity of the lead(II) nitrate solution if 22.00 mL of 2.00 M potassium iodide is needed to reach the equivalence point with 18.00 mL of lead (II) nitrate is 1.2M.

750. mL of solution.
Calculate the concentration of Nations in solution.

Answers

Taking into account the definition of molarity,  the concentration of Na₃PO₄ in solution is 0.192[tex]\frac{moles}{lliter}[/tex].

Definition of molarity

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{lliter}[/tex].

Concentration of Na₃PO₄ in solution

Being the molar mass of Na₃PO₄ 163.94 g/mole, that is, the amount of mass that a substance contains in one mole, the amount of moles that contains 23.6 g sample of Na₃PO₄ is calculated as:

[tex]23.6 gramsx\frac{1 mole}{163.94 grams} = 0.144 moles[/tex]

Then you know:

number of moles= 0.144 molesvolume= 750 mL= 0.750 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

[tex]Molarity=\frac{0.144 moles}{0.750 L}[/tex]

Solving:

Molarity= 0.192[tex]\frac{moles}{lliter}[/tex]

Finally, the concentration of Na₃PO₄ in solution is 0.192[tex]\frac{moles}{lliter}[/tex].

Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, then 337.92 moles of ozone will produce.

What is molecular formula?

Molecular formula is defined as an expression that defines a number of atoms of each element in one molecule of a compound.

It can also be defined as a chemical formula that gives the total number of atoms of each elements in each molecules of a substance.

Ozone is defined as a highly reactive gas composed of three oxygen atoms and form a layer above the earth surface called as ozone layer.

1 oxygen atom = 8 g

1 mole of ozone = 8 x 3 = 24 g

7.92 x 10²⁴ = 8110.08 g

24 g = 1 mole

So, 8110.08 g = 337.92 moles

Thus, Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, then 337.92 moles of ozone will produce.
