Number of moles in the K2SO4 sample
= (16/1000)*1.04= 0.01664 mol
Number of moles in the Ba(NO3)2 sample
= (14.3/1000*0.880)= 0.01258 mol
Since the reaction is a 1:1 ratio between the two reactants, the limiting reagent is the one containing a smaller number of moles, namely Ba(NO3)2.
The molecular mass of BaSO4 is 137.3+(32.06+4*16.00)=233.4
Therefore the theoretical yield of Barium Sulphate is
233.4*0.01258=2.937 g
Actual yield = 2.60 g (given)
Therefore the percentage yield = 2.60/2.937=88.54%
Answer:
1. the limiting reagent is Barium Nitrate (Ba(NO3)2)
2. the theoretical yield is 2.94 g
3. the percentage yield is 88.5%
I apologize for the mistake previous to this update.
Answer:
ATP supply will reduced or decrease drastically
Explanation:
ATP will reduced because carbohydrates are energy given food. Chemical energy are in carbohydrates, therefore when the undergo digestion i.e breakdown of larger pieces into smaller pieces, it is broken down into glucose i.e energy is released. Therefore, if there is now carbohydrates, ATP supply will reduced and there won't be energy needed for different cellular metabolic activities. The breakdown of carbohydrate supply energy.
By dividing mass with volume, you will end up with density
<span>i think the answer should be 2KOH +H2SO4=K2SO4+2H20</span>
Well I don’t know how you can “bake” a desert but if you can, try to not mix up the sugar and sand
