Depending on the strictness of your teacher you can name it as either of the following:
2-methyl-propane or iso-propane
Answer:
The products are KNO3 + PbCl2.....
Espero que te sirva.
Mass of Na2CO3 = 106g/mol
1 mole of Na2CO3 ------------ 106g
x moles of Na2CO3 ------------ 2.25g
x = 0.0212 moles of Na2CO3
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mass of NaOH = 40g/mol
1 mole of NaOH ----------------- 40g
x moles of NaOH -------------------- 0.800g
x = 0.02 moles of NaOH
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mass of Na2SO4 = 142g/mol
1 mole of Na2SO4 ---------------- 142g
x moles of Na2SO4 ------------------ 17.75g
x = 0.125 moles of Na2SO4
Answer:
Only some of the molecules of a weak base dissociate to produce hydroxide ions when mixed with water, but all of the molecules of a strong base dissociate to produce hydroxide ions.
Explanation:
- Generally, acids (weak or strong) dissociate to produce hydrogen ions, while bases (weak or strong) dissociate to produce hydroxide ions.
- Strong bases dissociate completely to produce hydroxide ions.
- But, weak bases do not dissociate completely to produce hydroxide ions, they dissociate by a percent depending on the strength of the base.
Only some of the molecules of a weak base dissociate to produce hydroxide ions when mixed with water, but all of the molecules of a strong base dissociate to produce hydroxide ions.
Answer:
The structure of the CO32– ion can be described in the Lewis formulation by these structures below. This means that a) two carbon-to-oxygen bonds are single bonds; the third is a double bond.
