Explanation:

Express the result of adding 856.6g and 23.86g to the correct number of significant figures.

856.6 +23.86  = 856.6 + 23.9 = 880.5

The result of adding 856.6 g and 23.86 g after rounding off to correct significant figures is 856.6 + 23.9=880.5.

What are significant figures?

Significant figures are used for establishment  of a number which is presented in the form of digits. These digits give a meaningful representation  to the numbers.

The significant figures are the significant digits which convey the meaning according to the accuracy. These provide precision to the numbers and hence are called as significant numbers.There are rules for counting significant figures which are as follows:

1)All non-zero digits are significant .

2)All zeroes which occur between non-zero digits are significant.

3)All zeroes to the left and right of  a non-zero digit are not significant.

4) All zeroes on right  of decimal are significant if a non-zero number follows them.

5)All zeroes on right side of non-zero digit are significant.

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.

Answers

Answer:

Before we can sketch the Lewis structures of molecules, we must first understand the octet rule. The octet rule asserts that when atoms combine to create compounds, electrons are gained, lost, or shared among them, resulting in a stable electron configuration defined by eight valence electrons as a result. These rules are used in conjunction with the main-group components of the second period.

Did all the silver ions get consumed in the reaction? The molar mass of silver is 107.87 g/mol. Justify your answer.

Answers

This problem is asking for the consumption of silver ions when silver nitrate is reacted with copper. In such a case, since no masses are given, we can use the following from similar problems:

Mass of empty beaker: 110.000 g

Mass of beaker with silver nitrate (after all additions) and copper: 331.634 g.

Mass of beaker with silver: 113.395 g.

This means we can write the following chemical equation:

[tex]Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag[/tex]

And thus calculate the mass of silver nitrate that will produce the following mass of silver:

[tex]m_{Ag}^{produced}=113.395g-110.000g=3.395g[/tex]

Next, we use the 2:2 mole ratio of silver to silver nitrate (silver ions source):

[tex]3.395gAg*\frac{1molAg}{107.87gAg}*\frac{2molAgNO_3}{2molAg} *\frac{169.87gAgNO_3}{1molAgNO_3} = 5.35gAgNO_3[/tex]

The step will be defined for the given mass of available silver nitrate which will be compared to 5.35 g (consumed mass) to see if they are the same (all consumed) or different (partial consumption).

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).

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

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.

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.
