What else can I help you with?
When a metal reacts with an acid what is the name of the new compound produced?
Two compounds are produced: 2Me + 2HB --> H2 + 2MeBHydrogen gas anda salt from that metal (Me+) and the anion left over (B-) from the acid (HB): eg. sodium chloride, NaCl.
What is left when you evaporate dilute sulfuric acid?
Driving off the water from dilute sulfuric acid will increase the concentration of the acid to the point where it will contain virtually no water.
What happens when a coin is placed in dilute acid?
When a coin is placed in dilute acid, such as hydrochloric acid, a chemical reaction occurs that dissolves the metal in the coin. The acid reacts with the metal to form metal chloride and hydrogen gas. Over time, the coin will corrode and eventually dissolve completely if left in the acid for a prolonged period.
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.
What happens if concentrated sulfuric acid is left open?
If concentrated sulfuric acid is left open, it will rapidly absorb moisture from the air, forming sulfuric acid fumes. This can lead to increased acidity and potential splashing hazards. Additionally, the acid may become diluted over time due to water absorption.

300 g of ammonia react with 36 moles of sulfuric acid to produce ammonia sulfate how many moles of excess sulfuric acid are left over after the reaction is complete?
26.9 - 27.4

How many moles of excess sulfuric acid are left over after the complete reaction of 300.0 g of ammonia with 36.0 moles of sulfuric acid producing ammonium sulfate?
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 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 the nameof the black substance produced when concentrated sulfuric acid is added to sugar?
Concentrated sulfuric acid strips the hydrogen and oxygen from sugar (sucrose) as water. Carbon is left. C12H22O11 + H2SO4 --> 12C + H2SO4. 11H2O
How many moles of excess sulfuric acid are left over after the reaction is complete 2 nh3 aq plus h2so4 aq nh4 2so4 aq?
To determine the moles of excess sulfuric acid left over after the reaction is complete, you need to compare the stoichiometry of the reactants. In this case, 2 moles of NH3 reacts with 1 mole of H2SO4. If you know the initial moles of NH3 and H2SO4 used in the reaction, you can calculate which one is in excess and how many moles of the excess reactant are left over.
400.0 g of ammonia react with 56.0 moles of sulfuric acid to produce ammonium sulfate How many moles of excess sulfuric acid are left over after the reaction is complete?
27.2 44.1 - 44.5 right answer dang
What are important uses of sulfuric acid in textile industry?
Sulfuric acid is commonly used in the textile industry for processes such as dyeing and printing of fabrics. It helps in setting the dyes on the fabric and improving color fastness. Sulfuric acid also helps in modifying the pH levels of the solutions used in textile processing.
