Answer:
a) HNO3 -> H+ + NO3- disassociation of Nitric Acid; to yield a Nitrate ion and a Proton, H+, or as a Hydronium ion H3O+
b) H2S04 -> Disassociation of Sulfuric Acid; simple way- 2H+ + SO4- -
c) H2S hydrogen sulphide in water is an acid; thus H+ HS- disassociation.
d) NaOH -> dissociation of Na+ + OH-; this is complete; sodium hydroxide is deliquescent, meaning it will draw water - EVEN from the air! Strong Base
e) Na2CO3 -> 2Na+ CO3- - Ionization of sodium carbonate - a salt
f) Na2S04 -> 2Na+ + SO4 - - ionization of sodium sulphate - a salt
g) NaCl -> Na+ + Cl- ionization of the salt, Sodium Chloride
Explanation:
Salts ionize at different rates; acids or bases dissociate; these are mostly strong acids and NaOH, a strong base.
Answer:
Emperical formula of the acid is CH2O
Molecular formula is C2H4O2
Explanation:
C. H. O
% by mass. 40. 6.71 53.29
MW. 12. 1. 16
Mole 40/12. 6.71/1. 53.29/16
3.33. 6.71. 3.33
3.33/3.33 6.71/3.33 3.33/3.33
1. 2. 1
Emperical Formula (EF): CH2O
Molecular Formula (MF)
Molecular Weight (MW) of acid = mole/mass = 0.00278/0.167 = 60g/mol
MF = (EF)n = 60
(CH2O)n = 60
(12+2+16)n = 60
30n = 60
n = 60/30 = 2
Molecular formula = (EF)n = (CH2O)2 = C2H4O2
You just need the left side equal the right side so the first one would be 2Mg + O2 = 2MgO
Answer:
I believe it's the lowest portion of the atmosphere
