<u>Answer:</u> The correct answer is Option A.

<u>Explanation:</u>

Mole ratio is defined as the ratio between the stoichiometric coefficients of the molecules present in the chemical reaction.

For the given balanced chemical equation:

3Fe+4H_2O\rightarrow Fe_3O_4+4H_2

By Stoichiometry of the reaction:

3 moles of iron metal reacts with 4 moles of water to produce 1 mole of iron oxide and 4 moles of hydrogen gas.

The mole ratio of Fe_3O_4:Fe=1:3

Hence, the correct answer is Option A.

Answer:

A- 1:3

Explanation:

Mole ratio is the ratio between the amount (In moles) of two substances involved in a chemical reaction.

For the reaction:

3Fe + 4H₂O → Fe₃O₄ + 4 H₂

There is 1 mole of Fe₃O₄ per 3 moles of Fe. In other words, the mole ratio of Fe₃O₄ to Fe is 1:3. Thus, answer is:

<em>A- 1:3</em>

I hope it helps!

NEED HELP ON 17,18,19,20,21,22,23. ONLY IF YOU ARE POSITIVE ABOUT THE ANSWER!!!!
Alex777 [14]

Answer:

17. D. Chemical change

18. C. Cell wall

19. D. To transfer matter and energy within and between organisms.

20. A. Transporting materials

21. C. Carbon dioxide

22. A. Cellular respiration

23. C. Produce food and give off oxygen

Explanation:

I have been able to supply the correct answers. The cell wall functions as a structure that provides structural support and protection to the cell. It is tough, flexible and at times rigid. In a chemical change, new materials with new properties are manufactured. So, the process of photosynthesis is a chemical change.

The endoplasmic reticulum actually transports material. It transports materials like protein and lipids made within the cell and sends it to where they are needed.

Carbon dioxide  is the the gas that animals give off and plants use it during photosynthesis. Cellular respiration involves the activities that result to the breaking down of food in order to release energy.

Ann [662]

Solution:

After the reaction of mixture is worked-up Washing three times the organic  with sodium carbonate helps to decrease the solubility of the organic layer into the aqueous layer. This allows the organic layer to be separated more easily.

And then the reaction washed by saturated NACL we have The bulk of the water can often be removed by shaking or "washing" the organic layer with saturated aqueous sodium chloride (otherwise known as brine). The salt water works to pull the water from the organic layer to the water layer.

A mixture of helium, nitrogen, and oxygen has a total pressure of 752 mm Hg. The
NISA [10]

Answer: The partial pressure of oxygen in the mixture is 321 mm Hg

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

p_{total}=p_{He}+p_{N_2}+p_{O_2}

Given : p_{total} = total pressure of gases = 752 mm Hg

p_{He} = partial pressure of Helium = 234 mm Hg

p_{N_2} = partial pressure of nitrogen = 197 mm Hg

p_{O_2} = partial pressure of oxygen = ?

Putting in the values we get:

752mmHg=234mmHg+197mmHg+p_{O_2}

p_{O_2}=321mmHg

The partial pressure of oxygen in the mixture is 321 mm Hg
