What would happen if the sulfuric acid was left out in the reaction between acetic anhydride and salicylic acid to prepare acetylsalicylic acid?
If the sulfuric acid is left out of the reaction, the acetylsalicylic acid synthesis may proceed at a slower rate or not to completion. The presence of sulfuric acid helps catalyze the reaction and improves the yield of acetylsalicylic acid. It also helps in the dehydration of acetic acid formed during the reaction.
300.0g of ammonia react with 36.0 moles of sulfuric acid to produce ammonium sulfate how many moles of excess sulfuric acid are left over after the reaction is complete?
The equation for the reaction is: H{2}SO{4} + 2NH{3} → (NH{4}){2}SO{4} [Numbers in braces are supposed to be subscripts, but I can't do them here.] This says that 1 mole of sulphuric acid reacts with 2 moles of nitrogen to create 1 mole of ammonium sulphate. 1 mole of a substance weighs the same as its atomic weight in grams. 1 mole of NH{3} weighs 14 + 3 × 1 = 17 g Thus 2 × 17 g = 34 g of ammonia react with 1 mole of sulphuric acid. To react with 500 g of ammonia requires 500 g ÷ 34 g/mol ≈ 14.7 moles of sulphuric acid Therefore there will be 51.0 - 14.7 = 36.3 moles of sulphuric acid left.
What are the dangers of sulphuric acid?
Concentrated Sulphuric acid is used in a variety of chemical reactions as a de-hydrating agent.So it dehydrates or completely absorbs water from any surface on which it falls.If it falls on the human skin,the portion of the skin exposed to the acid could experience severe burning sensation.So it is advisable to use gloves or long fillers(like ink fillers)to put some drops of the acid into a test tube etc..If you accidentally spill some drops of concentrated acid on sugar you will find that the sugar turns black.This is because the sugar gets charred and due to dehydration(removal of water molecule),only carbon is left behind.Carbon is a major component of sugar. Inhaling the fumes can also cause serious lung damage.

To react with 300 g of ammonia requires 300 g ÷ 34 g/mol ≈ 8.8 moles of sulphuric acid Therefore there will be 36.0 - 8.8 = 27.2 moles of sulphuric acid left.
What is H2SO4 elements?
-There are three elements in this compound and 7 atoms. -Hydrogen (Fe):2 atoms -Sulphur (S):1 atom -Oxygen (O):4 atoms -Elements are always shown by a capital letter sometimes followed by another lower case letter. The all make Sulphuric acid(H2SO4). -Metals are usually in front of a product such as FeSO4 and non-metal at the back. The equation for this compound is Hydrogen+Sulphur+Oxygen= Sulphuric acid.The reactants are put at the left side and the product at the right side. -It's Sulfuric acid for the Americans and Sulphuric acid for the British students. -I fancy Georgina Miners!
What is left behind in the filter when you mix copper oxide with sulphuric acid?
Copper(s)
What would happen if you left a strawberry on the bench uncovered for a day?
it would dry out
Why acetone should not left uncovered?

What ions does an acid form in soltion?
H+ ions cause the acidity. The anion will simply be what's left of the molecule after dissociation. A molecule of sulphuric acid (H2SO4) for instance forms two H+ ions and one SO42- ion when dissolved in water

What would happen if the beaker is left uncovered during the development of the chromatogram?
Bad things happen. The mobile phase evaporates and thus it's composition changes. The vapor phase above the chromatogram is not saturated or at equilibrium, and this affects the movement of the sample on the solid phase.
Why add sulphuric acid in sulphated ash?
Sulfuric acid is added in the process of determining sulphated ash to help decompose organic matter present in the sample to ensure complete combustion. This is important to accurately measure the inorganic residue left behind, which is the sulphated ash content.

Depends on how much but worse case scenario it eats your stomach and mouth
