oksian1 [2.3K]3 years ago
5 0

Answer:

a mole of lactic acid = 90 g

a 0.5 M solution would require 1/2 mol or 45 g

Explanation:

The molecular mass is 90 d, the combined atomic masses of its atoms.

How many grams of LiCl are required to make 2.0 L of 0.65 M LiCl solution?
makkiz [27]

Answer:- 55 g of LiCl are required to make 2.0 L of 0.65 M solution.

Solution:- Given-

molarity of the solution = 0.65M

Volume of solution = 2.0 L

molarity of solution = \frac{moles of solute}{volume of solution in liter}

It could be arranged as...

moles of solute = molarity x volume of solution

moles of solute = 0.65 x 2.0 = 1.3 moles

Molar mass of LiCl is 42.39 g/mol.

So, mass of LiCl required = 1.3 mol x 42.39g/mol = 55 g

bartleby whihch of the foololwing is the correct cell notation for the reaction Hg2 Cd(s)-> Cd2 2Hg(l)
Misha Larkins [42]

Cd2+ + 2Hg Cd + Hg22+. Both Cd2+ + 2e Cd(s) -0.40 and Hg22+ + 2e 2Hg(l) 0.79

A chemical reaction known as an oxidation-reduction (redox) reaction includes the exchange of electrons between two substances.

Any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by acquiring or losing an electron is referred to as an oxidation-reduction reaction. Decomposition Reaction is one of the several redox reactions.

This is the redox reaction's overall cell potential. Cd2+ + 2Hg Cd + Hg22+. Both Cd2+ + 2e Cd(s) -0.40 and Hg22+ + 2e 2Hg(l) 0.79

Reduction describes the increase in electrons. Oxidation and reduction always occur jointly because any loss of electrons by one substance must be followed by a gain of electrons by another.

Therefore, oxidation-reduction processes or simply redox reactions are other names for electron-transfer events.

What are the three particles of an atom?
Dmitry [639]
The three particles found in an atom are the protons, neutrons and electrons. Protons have a positive charge. Electrons have negative charge. Lastly, neutrons have no net electrical charge. Protons and neutrons are much heavier than electrons and are located in the center of the atom.
