Reaction 2 occurs when an excess of 6 M HCI(aq) solution is added to 100. mL of NaOCl(aą) of unknown concentration. If the reaction goes to completion and 0.010 mol of Cl2(g) is produced, then what was the molarity of the NaOCl(aq) solution? (A) 0.0010 M
(B) 0.010 M
(C) 0.10 M
(D) 1.0 M

Answers

Answer 1
Answer:

The molarity of the NaOCl solution is 0.10M

The correct answer to the question is Option C. 0.10 M

We'll begin by calculating the number of mole of NaOCl required to produce 0.010 mole of Cl₂.This can be obtained as follow:

NaOCl + 2HCl —> Cl₂ + NaCl + H₂O

From the balanced equation above,

1 mole of NaOCl reacted to produce 1 mole of Cl₂.

Therefore

0.010 mole of NaOCl will also react to produce 0.010 mole of Cl₂.

  • Finally,we shall determine the molarity of the NaOCl solution.

Mole of NaOCl = 0.01 mole

Volume = 100 mL = 100 / 1000 = 0.1 L

Molarity of NaOCl =?

Molarity = mole / Volume

Molarity of NaOCl = 0.01 / 0.1

Molarity of NaOCl = 0.1 M

Therefore, the molarity of the NaOCl solution is 0.1 M

Answer 2
Answer:

Answer:

Option C 0.10 M

Explanation:

you are not providing the reaction, but luckily we have data to write the equation. We know that we are taking HCl and NaOCl to produce Cl2, the reaction is as follow:

NaOCl + 2HCl ---------> Cl₂ + NaCl + H₂O

From this reaction, we know that we have excess of acid that is added to 100 mL (0.1 L) of NaOCl, and this produces 0.010 moles of Chlorine.

All we have to do here, is apply stechiometry. We already know that the acid is in excess, so the moles produced would be the moles of the limiting reactant, in this case, the NaOCl.

According to the reaction NaOCl and Cl2 has a mole ratio of 1:1, so the moles of Cl2 would be the same moles that NaOCl lost so:

moles Cl2 = moles NaOCl = 0.010 moles

Then the concentration:

M = 0.010 / 0.1

M = 0.10 M

This is the molarity of NaOCl

Which element has the following mass spectrum?


Will mark as Brainliest✅

Answers

Cf, the element has the following mass spectrum. Therefore, option (D) is correct.

California (Cf) is a radioactive element with a complicated mass spectrum that shows its isotopic makeup and decay trends. Peaks in Cf's mass spectrum denote isotopes with differing mass-to-charge ratios. These peaks signify isotopes, which are elemental atoms with varying neutron counts.

The mass spectrum yields important information about the sample's isotope abundance and masses. Researchers can determine Cf's isotopic distribution and nuclear characteristics like decay modes and half-lives by analyzing peaks and intensities. This is crucial since Cf's radioactivity and prospective uses in nuclear research and medicine are vital.

In conclusion, Californium's massspectrum reveals its isotopic makeup and behavior, helping researchers understand its characteristics and uses. Therefore, option (D) is correct.

How many moles of Fe(OH)2 are required to produce 7.4 moles of Fe3(PO4)2

Answers

Considering the reaction stoichiometry, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.

The balanced reaction is:

3 Fe(OH)₂ + 2 H₃PO₄ → Fe₃(PO₄)₂ + 6 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

  • Fe(OH)₂: 3 moles
  • H₃PO₄: 2 moles
  • Fe₃(PO₄)₂: 1 mole
  • H₂O: 6 moles

Then you can apply the following rule of three:  if by reaction stoichiometry 1 mole of Fe₃(PO₄)₂ requires 3 moles of Fe(OH)₂, 7.4 moles of Fe₃(PO₄)₂ require how many moles of Fe(OH)₂?

amount of moles of Fe(OH)_(2) =(7.4 moles of Fe_(3) (PO_(4) )_(2) x3moles of Fe(OH)_(2) )/(1mole of Fe_(3) (PO_(4) )_(2) )

amount of moles of Fe(OH)₂= 22.2 moles

Finally, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.
