You mix 245.0 gallons of a mixture containing 4.00 wt% nacl (sodium chloride) and 96.00 wt% water (solution density = 1.0253 g/cm3) with a v2-gallon solution that is 20.00 wt% nacl and 80.00 wt% water (solution density = 1.1453 g/cm3). you want to produce a mixture containing 19.00 wt% nacl. what is v2 in gallons?

2b2t

explanation:

2b2t

thats how its supposed to be

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
