Let’s assume that other salts found in hard water are: LiF, MgCl2, NaBr, BeI2, AlCl3, and CaCl2. The more ionic a compound is (more ionic character it has), the more dissociation of its ions is generated and potential harm when ingested. Having said that: A. Choose TWO of these salts and determine which of the them is more potentially harmful, considering its ionic character.
B. Show the Lewis structure in each case (the TWO chosen ones), indicating transfer of electrons.
C. Write the electron configurations of the elements before and after the transference of electrons, and explain their meaning (for your TWO salts).

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

give me abc and i will get it for u.
