What is the percentage of Ba compound when 0.269 g sample of Ba compound was treated with excess H2SO4 0.0891 g of BaSo4 was formed?
32%
How do you test for sulphate ions?
add barium chloride or barium nitrate to a solution containing sulphate ions SO4 2-. To the same solution add hydrochloric acid in excess. OBSERVATIONS, a white precipitate which is insoluble in excess acid confirms presence of SO42- IF IT DISSOLVES then it confirms SO32- ----------------------------------------- 1) Add barium nitrate solution under acidic conditions (use an equal volume of hydrochloric acid) to the unknown solution 2) A white precipitate of barium sulphate forms if sulphate ions are present
Compound used to store excess energy reserves?
Triglyceride
Is potassium and sulferan covalent compound?
Potassium and sulfur react to give K2S potassium sulfide, an ionic compound. With excess sulfur polysulfides can be formed- these contain Sn2- ions.
2-propanol was used to remove excess NAOCl in the reaction. what organic compound would be formed from the reaction of 2-propanol and NaOCl?
acetone
What is the percentage of Ba compound when 0.269 g sample of Ba compound was treated with excess H2SO4 0.0891 g of BaSo4 was formed?
32%
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
Excess consumption of soft drinks may lead to excess stomach acid how is this problem normally treated?
excess consumption of soft drinks may lead to excess stomach acid.Why? and how is this treated
A sample of 0.3220 g of an ionic compound containing the bromide ion Br is dissolved in water and treated with an excess of AgNO3 If the mass of the AgBr precipitate that forms is 0.6964 g?
A sample of 0.3220 g of an ionic compound containing the bromide ion Br is dissolved in water and treated with an excess of AgNO3 If the mass of the AgBr precipitate that forms is 0.6964 g then bromide=0.3220g and AgBr precipitate=0.6964.

Why phenol does not dissolve in water when excess?
Phenol (C6H5OH) is more organic and is a covalent compound. The percentage of carbon is more compared to -OH (the polar part). Hence phenol will dissolve in organic solvents and not in water.
Which ions is the limiting reagent and which is the reagent in excess when barium sulphate is made?
When barium sulfate is made, the limiting reagent is the one that is completely consumed in the reaction and determines the amount of product formed. In this case, if barium ions (Ba2+) and sulfate ions (SO42−) are the reactants, the limiting reagent would be the one that is present in lower molar quantity. The one in excess would be the one that is present in higher molar quantity. Without the quantities of each ion provided, it is difficult to determine which is the limiting reagent and which is in excess.
what causes the bubble to turn into gas?
Excess air being excreted from the compound it came from.
What is the difference between a limiting reactant and an excess reactant?
the limiting reactant is how much of a compound or solution you need to make an experiment possible. the excess reactant is the amount left over from the other compound or solution used (the other reactant that is used)
What percentage of the contribution margin is profit on units sold in excess of the breakeven point?
50%
What liquids can you use to change the color of litmus paper?
Any acid or base should do the trick.Any compound with excess hydrogen ions (H+) or excess hydroxide ions (OH-). Also, any compound that absorbs hydrogen ions (H+) or hydroxide ions (OH-).
