Chlorine is used by textile manufacturers to bleach cloth. Excess chlorine is destroyed by its reaction with sodium thiosulfate,

Na2S2O3, as follows:
Na2S2O3(aq) + 4Cl2( g) + 5H2O right-arrow 2NaHSO4(aq) + 8HCl(aq)

1)How many moles of HCl can form from 0.21 mol of Cl2?

2)How many moles of H2O are required for the reaction of 0.18 mol of Cl2?

Na2S2O3(aq) + 4Cl2( g) + 5H2O = 2NaHSO4(aq) + 8HCl(aq)

1)How many moles of HCl can form from 0.21 mol of Cl2?
0.21 mol Cl2 ( 8 mol HCl / 4 mol Cl2 ) = 0.42 mol HCl

2)How many moles of H2O are required for the reaction of 0.18 mol of Cl2?
0.18 mol Cl2 ( 5 mol H2O / 4 mol Cl2 ) = 0.225 mol H2O

3)How many moles of H2O react if 0.50 mol HCl is formed?
0.50 mol HCl ( 5 mol H2O / 8 mol HCl ) = 0.3125 mol H2O

A prion is an infectious self-reproducing protein structure. true or false
Alexandra [31]

Answer:

True is the correct answer.

Explanation:

  • The statement that a prion is an infectious, self-reproducing protein structure is true.
  • prion is an infectious particle and they do not have genetic material.
  • Prion present in the brain region that results in deadly neurodegenerative illnesses in humans and animals.
  • Prions are the self-producing proteinaceous infectious capable of transferring infection in the absence of the nucleic acids.
  • prions enter in the brain by an infection and they emerge from the variation in the gene that encodes the protein and once the prions present in the brain multiply by causing the benign proteins to refold into an abnormal form.

HELP. What change in state occurs when water boils? And why does this change happen??
Lapatulllka [165]
Boiling is the process by which a liquid turns into a vapor when it is heated to it’s boiling point. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid. Boiling is a physical change and molecules are not chemically altered during the process.
Hope that helped!
