Which member of each pair produces the more acidic aqueous solution? Match the words in the left column to the appropriate blanks in the sentences on the right. ResetHelp When comparing Ca(NO3)2 or NiBr2, the one that produces a more acidic aqueous solution is NiBr2 N i B r 2 When comparing C a ( N O 3 ) 2 or N i B r 2 , the one that produces a more acidic aqueous solution is blank.. When comparing ZnBr2 and CdCl2, the one that produces a more acidic aqueous solution is When comparing Z n B r 2 and C d C l 2 , the one that produces a more acidic aqueous solution is blank.. When comparing CuCl or Cu(NO3)2, the one that produces a more acidic aqueous solution is When comparing C u C l or C u ( N O 3 ) 2 , the one that produces a more acidic aqueous solution is blank..

Explanation:

Ionjc equation

ZnCl2 --> Zn2+ + 2Cl-

CdCl2 --> Cd2+ + 2Cl-

Both Cd2+ and Zn2+ have the same number of charge so lewis acid does not apply. Zn2+ has a smaller radius than Cd2+ hence it will produce a more acidic solution.

Ionic equation

Ca(NO3)2 --> Ca2+ + 2NO3^-

NiBr2 --> Ni2+ + 2Br-

Both Ni2+ and Ca2+ have the same number of charge so lewis acid does not apply. Ni2+ has a smaller radius than Ca2+ hence it will produce a more acidic solution.

Ionic equation

CuCl --> Cu+ + Cl-

Cu(NO3)2 --> Cu2+ + 2NO3^-

The hardness of a lewis acid increases with increasing positive charge, as the electron density is more concentrated. Therefore, Cu2+ is the stonger acid in solution than Cu+, being less polarizable that is the strength to pull electrons in Cu2+ is stronger.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

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.
