Answer: Theoretical mass of sodium sulphate ( 
) is 514.118 grams.
Explanation: For a given reaction,
As NaOH is used in excess, therefore it is an excess reagent and 
is a limiting reagent as the quantity of the product will depend on it.
We are given 355 grams of .
Molar mass of = 98.079 g/mol
Molar mass of = 142.04 g/mol
1 mole of is producing 1 mole of , so
98.079 g/mol of will produce 142.04 g/mol of
355 grams of will produce = 
of
Mass of = 514.118 grams
Answer: Flow rate is inversely proportional to viscosity.
Explanation: The relation is called Poiseuille's law, which describes the smooth flow of a fluid along a tube.
CO2 and H2O react to form H2CO3 and two bonds are broken each in CO and H2O to form H2CO3.
<h3>What is chemical bonding?</h3>
Chemical bonding refers to the forces of attraction which hold atoms of the same or different elements together in order to form stable compounds or molecules .
Chemical bonding may be either ionic or covalent.
The greater the number of bonds in a compound, the more stable the compound.
During chemical reactions, bonds are broken and new binds are formed.
There are two bonds each in CO2 and H2O.
This, in the reaction between CO2 and H2O react to form H2CO3, , the number of bonds broken in H2O is two and in CO2 is two.

Answer:
Moles of 
= 6 moles
Explanation:
The reaction of 
and 
to make is:
⇒
The above reaction shows that 2 moles of Sc can react with 3 moles of to form 
Mole Ratio= 2:3
For 10 moles of Sc we need:
Moles of = 
Moles of = 
Moles of =15 moles
So 15 moles of are required to react with 10 moles of but we have 9 moles of , it means is limiting reactant.
Moles of ScCl_3= 6 moles
