What is the KB of Na2CO3?
The Kb of Na2CO3 is equal to 2.1 x 10^-4. Carbonate ion is the ion that results from the dissociation of Na2CO3.
How do you balance this equation caoh2 plus na2co3 plus hno3?
Ca(OH)2 + Na2CO3 = CaCO3 + 2 NaOH
What is the molecular weight of Na2CO3?
The molecular weight of Na2CO3 is: (2 X 23) + 12 + (3 X 16) = 106
What is molecularity by using examples?
Molecularity is the sum of stoicheometric coefficients of the reactants in a chemical reaction.2 AgNO3 + Na2CO3 = Ag2CO3 + NaNO3The molecularity is: 2 (from AgNO3) + 1 (from Na2CO3) = 3
What is the chemical reaction equation for Na2CO3 and CaCl2?
Na2CO3 (aq) + CaCl2 (aq) -----> 2 NaCl(aq) + CaCO3(s) This is a double displacement reaction.
What is the KB of Na2CO3?
The Kb of Na2CO3 is equal to 2.1 x 10^-4. Carbonate ion is the ion that results from the dissociation of Na2CO3.
Formula sodium carbonate?
sodium: Na + carbonate: CO3 2- therefore... Na2CO3 the "2" and "3" are subscripts
How do you balance this equation caoh2 plus na2co3 plus hno3?
Ca(OH)2 + Na2CO3 = CaCO3 + 2 NaOH
How many points is a sack in the end zone?
2, a sack in the end zone is considered a safety which is 2 points
What is the reaction between NH4OH and Na2Co3?
Na2CO3 + 2 NH4OH = (NH4)2CO3 + 2 NaOH
What is the molecular weight of Na2CO3?
The molecular weight of Na2CO3 is: (2 X 23) + 12 + (3 X 16) = 106
What is the endpoint of 7 2?
The end points are 7 and 2.
What is between 2 points?
A line segment is between two end points
Which number belongs in the blank in order for this to be a balanced equation Na2CO3 plus CaCl2 NaCl plus CaCO3?
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
What shape has 2 end points?
The shape that has 2 end points is known as a line segment. A line segment is a line that can go on forever, but it has a start point and an end point, no matter where it stops.
How many moles is 0.75g of Na2CO3?
The formula mass of sodium carbonate, Na2CO3 is 2(23.0) + 12.0 + 3(16.0) = 106.0Amount of Na2CO3 = mass of sample/molar mass = 0.75/106.0 = 0.00708mol There are 0.00708 moles of Na2CO3 in a 0.75g pure sample.
What is the balanced chemical equation for zinc sulfate and calcium chloride?
Only chemical formulas, not if they are reacting. Na2CO3 and CaCl2
