Well, the answer kind-of explains all I would want to say! Feel free to copy and paste this on your assignment, but do NOT use the sample answer like the other person who answered this did. (The sample answer you should NOT use: "The cells of the body produce waste materials. The body needs to get rid of these waste materials because they can make us sick. Getting rid of this waste keeps us healthy.") It could make your teachers or parents suspicious of your work! Anyways, have a good day! ❥

Answer:

15.28 mL

Explanation:

From the question given above, the following data were obtained:

Molarity of stock solution (M₁) = 4.5x10¯⁴ M

Volume of diluted solution (V₂) = 275 mL

Molarity of diluted solution (M₂) = 2.5×10¯⁵ M

Volume of stock solution (V₁) needed =.?

The volume of the stock solution needed can be obtained by using the dilution formula as illustrated below:

M₁V₁ = M₂V₂

4.5x10¯⁴ × V₁ = 2.5×10¯⁵ × 275

4.5x10¯⁴ × V₁ = 0.006875

Divide both side by 4.5x10¯⁴

V₁ = 0.006875 / 4.5x10¯⁴

V₁ = 15.28 mL

Therefore, the volume of the stock solution needed is 15.28 mL

Answer:

30.11×10²³ molecules

Explanation:

Given data:

Mass of NaOH = 200.0 g

Number of molecules of water formed = ?

Solution:

Chemical equation:

2NaOH + H₂SO₄      →     2H₂O + Na₂SO₄

Number of moles of NaOH:

Number of moles = mass/molar mass

Number of moles = 200 g/ 40 g/mol

Number of moles = 5 mol

Now we will compare the moles of NaOH and H₂O.

                      NaOH         :        H₂O

                          2             :          2

                         5              :            5

Number of molecules of water:

1 mole contain 6.022×10²³ molecules

5 mol × 6.022×10²³ molecules / 1mol

30.11×10²³ molecules

Explanation:

1 mole is equal to 1 moles Iron(III) or 832.29538 grams, so 2 moles Iron(III) = 1664.59076 grams

Answer:

1.The law does not hold true if the different isotopes of the element are involved in making chemical compound.

2.The law is not applicable when elements combine in the same ratio but different compounds are formed.

Answer:

Explanation:

1 is true

2 is false

3 is true

4 is true

5 is false

That is what I got from researching.

Only about 3% of the water in the Earth is fresh water and about 75 % of the fresh water on Earth is frozen in ice sheets.  

• The most vital element present on the Earth is water. All the living beings are dependent on it.  

• Water is present in the majority of the Earth, however, of this only 3% of the water is freshwater, the rest is saline and undrinkable.  

• Of this 3%, the 75 percent of the freshwater is present in the form of ice and glaciers in the polar region.  

• The remaining 24 percent is the groundwater and the rest 1 percent includes the waters of rivers, lakes, and ponds.  

• The prime source of usable freshwater is present in the trapped form in the ice and glaciers.  

Thus, the correct statements are 1st and 3rd.

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, the correct option is option A.

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. Just like the N and S poles on bar magnets, electrons and protons attract each other.

Therefore,  the correct option is option A.

Answer:

Molecular formula = C₄H₁₂O₂

Explanation:

Given data:

Percentage of hydrogen = 13.80%

Percentage of carbon = 51.02%

Percentage of oxygen = 35.18%

Molecular formula = ?

Solution:

Number of gram atoms of H = 13.80 / 1.01 = 13.6

Number of gram atoms of O = 35.18 / 16 = 2.2

Number of gram atoms of C = 51.02 / 12 = 4.25

Atomic ratio:

            C                      :      H             :         O

           4.25/2.2           :     13.6/2.2     :       2.2/2.2

            2                      :        6          :        1

C : H : O = 2 : 6 : 1

Empirical formula is C₂H₆O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = C₂H₆O = 46 g/mol

n = 88 / 46

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₂H₆O)

Molecular formula = C₄H₁₂O₂

Explanation:

Answer:

V₂ = 238.05 L

Explanation:

Given data:

Final volume = ?

Initial volume = 13.40 L

Initial pressure = 1.51 atm

Final pressure = 65 mmHg ( 65/760 = 0.085 atm)

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.51 atm × 13.40 L = 0.085 atm × V₂

V₂ = 1.51 atm × 13.40 L /  0.085 atm

V₂ = 238.05 L

Answer: B) must be available for workers to review

Explanation:

WHMIS is a Canadian program which gives information to the employers about the workers knowledge about hazardous materials that are used in the workplace. It is ensured that the worker labelled the hazardous material at the workplace, material safety data sheet should be created to supplement the label, and worker's education program for learning the safety precautions is also conducted.

The material safety data sheets are created by the employers and their is no expiry date for such data for workers instead they receive a next recommended training date for participating in the training and avail another certification after the completion of first year.

Answer:

This accepting atom will then become an anion. The anion has more electrons than protons. This means that some of the electrons will not be canceled out, giving the atom an overall negative charge.

If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. If there are equal numbers of protons and electrons, then the object is electrically neutral.

Answer:

1. 0.0033 moles of water.

2. 270g of water

3. 12.8g NaCl

4. 6.72g NaHCO3

5. 1190moles Fe2O3

Explanation:

To convert moles to grams or vice versa we require tu use molar mass of the substance as follows:

1. Molar mass water: 18g/mol

0.060g * (1mol / 18g) = 0.0033 moles of water

2. Molar mass water: 18g/mol

15 moles H₂O * (18g / 1mol) = 270g of water

3. We can assume all sea salt is NaCl -Molar mass: 58.44g/mol-

750g NaCl * (1mol / 58.44g) = 12.8g of NaCl

4. Molar mass NaHCO₃: 84g/mol:

0.080mol * (84g/mol) = 6.72g NaHCO3

5. Molar mass Fe2O3: 159.69g/mol:

190kg = 190000g * (1mol / 159.69g) = 1190moles Fe2O3
