Answer:
The answer in this question is show you made Sodium Hydroxide and Hydrogen Gas.In order to do the products of the reaction relate to the phenol red test and the splint test you need to show that you made Sodium Hydroxide and Hydrogen Gas. Show that you made Sodium Hydroxide and Hydrogen Gas so that the products of the reaction relate to the phenol red test and the splint test.
The awnser is A. Idek I looked it up so yeah that’s the awnser
Answer:
Choice A: approximately .
Explanation:
Note that the unit of concentration, , typically refers to moles per liter (that is: .)
On the other hand, the volume of the two solutions in this question are apparently given in , which is the same as (that is: .) Convert the unit of volume to liters:
- .
- .
Calculate the number of moles of formula units in that of the solution:
.
Note that (sulfuric acid) is a diprotic acid. When one mole of completely dissolves in water, two moles of ions will be released.
On the other hand, (sodium hydroxide) is a monoprotic base. When one mole of formula units completely dissolve in water, only one mole of ions will be released.
ions and ions neutralize each other at a one-to-one ratio. Therefore, when one mole of the diprotic acid dissolves in water completely, it will take two moles of to neutralize that two moles of produced. On the other hand, two moles formula units of the monoprotic base will be required to produce that two moles of . Therefore, and formula units would neutralize each other at a two-to-one ratio.
.
.
Previous calculations show that of was produced. Calculate the number of moles of formula units required to neutralize that
.
Calculate the concentration of a solution that contains exactly of formula units:
.
Answer:
2 moles
Explanation:
Hi there !!
Given volume = 44.8 litres
Molar volume = 22.4 litres
No: of moles = Given volume / Molar volume
= 44.8 / 22.4 = 2 moles
Answer:
The correct option is: protons; electrons
Explanation:
The electron transport chain contains a series of biomolecules that are involved in the transfer of electrons by redox reactions.
This process involves the transfer of electrons from an <u>electron donor molecule to an electron acceptor molecule</u>, resulting in the <u>release of energy.</u> Some amount of this energy is then used in <u>pumping the protons across the biological membrane.</u>
