Find the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide.

Answers

The volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L

The reaction of sulphuric acid and sodium hydroxide is expressed as:

[tex]2NaOH + H_2SO_4 ==> Na_2SO_4 + 2H_2O[/tex]

Determine the moles of NaOH present

Molar mass of NaOH = 23 + 16 + 1 = 40g/mole

Given that mass of NaOH is 75.0g

Mole of NaOH = 75/40  = 1.875moles

Determine the number of moles [tex]H_2SO_4[/tex] needed to react with 1.875 moles NaOH

Moles of [tex]H_2SO_4[/tex] = [tex]\frac{1.875}{2} = 0.9375moles of H_2SO_4[/tex]

Recall that volume = Molar mass * number of moles

Volume of [tex]H_2SO_4[/tex] =  0.160 * 0.9375

Volume of  [tex]H_2SO_4[/tex] = 0.15L

Hence the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L

Determine the wavelength of a radio station transmitting a broadcast at 520 Megahertz.

Answers

The wavelength of the radio station broadcasting at 520 megahertz is 0.58m.

HOW TO CALCULATE WAVELENGTH:

The wavelength of a wave can be calculated by dividing the speed of the wave by its frequency as follows:

λ = v/f

Where;

v= velocity of the wave (3 × 10⁸m/s)f = frequency (Hz)

According to this question, a radio station is transmitting a broadcast at 520 Megahertz. The wavelength is calculated as follows:

λ = 3 × 10⁸ ÷ 5.2 × 10⁸

λ = 0.577 × 10⁸-⁸

λ = 0.58m

Therefore, wavelength of the radio station broadcasting at 520 megahertz is 0.58m.

Explain the law of conservation of mass. Give an example of how mass is conserved using numbers to justify your answer.

Answers

Answer:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction.

For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Another example, solar panels don't create solar energy. They harness energy from the sun and transform it into another type of energy (electricity).

What is the heat gain per unit length of the duct.

Answers

Answer:

The outer duct surface is heated 25°C by the air from 10°C to 35°C;

This heat gain is simply divided by 0.2m to get heat gain per unit length:

A scientist wants to make a solution of tribasic sodium phosphate, Na3PO4, for a laboratory experiment. How many grams of Na3PO4 will be needed to produce 400. mL of a solution that has a concentration of Na ions of 1.00 M

Answers

Answer:

21.86 grams

Explanation:

It is important to note that for every mol of Na3PO4 there is, 3 mols of Na ions are produced.

Na+=1m(0.4l), so mols of Na3PO4= 0.4/3= 0.13333... mols

the molar mass of Na3PO4 is 163.94 grams/mol. 0.1333*163.94=21.86 grams of Na3PO4.

8) What mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride?​

Answers

Answer:

38.3 g

Explanation:

8) What mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride?​

first write, then balance the equation

Fe + Cl2-------------> FeCl3

2Fe + 3Cl2----------> 2FeCl3

2 moles of Fe require 3 moles of Cl2

the atomic mass of Fe is 56

20/56= 0.36 moles of Fe

this requires o.36 X 3/2 = 0.54 moles of Cl2

Cl2 has a molar mass of 35.5 X 2=71

1 mole of Cl2 is 71g

0.54 moles is 0.54 X 71 g= 38.3 g

The mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride is 38.3 g.

What is mass?

Mass is defined as a numerical representation of the fundamental characteristic of all matter, inertia.

It can also be defined as a dimensionless number used to describe the mass of a particle or item.

[tex]\rm 2Fe + 3Cl_2\rightarrow2FeCl_3[/tex]

As per the reaction 3 mole of chlorine is required for 2 mole of fluorine.

Atomic mass of fluorine = 56

Moles of Fe = 20 / 56

                    =  0.36 moles

This require 0.36 x 3/2 = 0.54 moles of Cl₂

Molar mass of Cl = 35.5

So for Cl₂ = 2 x 35.5 = 71 moles

For 1 mole of Cl₂ = 71 moles is needed

So, for 0.54 moles = 71 x 0.54

                               = 38.3 g

Thus, the mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride is 38.3 g.
