What is formed when metal reacts with acid?
When a metal reacts with an acid, it forms a salt and hydrogen gas. The metal displaces the hydrogen in the acid, leading to the formation of the salt (metal compound) and the release of hydrogen gas as a byproduct.
What IS THE REACTION OF calcium hydroxide AND nitrous acid?
The reaction between calcium hydroxide and nitrous acid (HNO2) would result in the formation of calcium nitrite [Ca(NO2)2] and water (H2O). The balanced chemical equation for this reaction is: Ca(OH)2 + 2HNO2 → Ca(NO2)2 + 2H2O
Why should you not put calcium metal into a dilute acid?
Putting calcium metal into a dilute acid can be dangerous as it can produce hydrogen gas rapidly, leading to a build-up of pressure in the container, potentially causing it to explode. Additionally, the reaction between calcium metal and acid is highly exothermic and can release a large amount of heat, which can cause burns or other injuries.
What would you observe before dilute acetic acid is added to calcium carbonate?
Before dilute acetic acid is added to calcium carbonate, you would observe that the calcium carbonate is a white solid. There may be no visible reaction or bubbling occurring prior to the addition of the acid.
Is Nitrous an acid or base?
Nitrogen is neither. Nitrogen gas is simply N2, which has no hydrogen or hydroxide ions, which distinguish acids and bases. Nitrogen can be a part of a base or acid. For instance, nitric acid is HNO3, which obviously contains nitrogen.
What happens when calcium metal is added to a dilute solution of hydrochloric acid?
When calcium metal is added to a dilute solution of hydrochloric acid, a chemical reaction takes place in which calcium reacts with hydrochloric acid to produce calcium chloride and hydrogen gas. The balanced chemical equation is: Ca (s) + 2HCl (aq) -> CaCl2 (aq) + H2 (g)
Is calcium acid?
No. Calcium is a metal.
What does HNO2 stand for?
HNO2 stands for nitrous acid. It is a weak acid that is commonly used in chemical reactions and as a reagent in laboratory experiments.
Is calcium carbonate carbonic acid?
No, calcium carbonate (CaCO3) is the calcium salt of carbonic acid (H2CO3). If a compound has the name of a metal in it (sodium, calcium, copper, etc) it is generally not an acid but a salt. A salt is formed when a metal ion or other positive ion takes the place of hydrogen in an acid.
What is the word equation for hydrochloric acid and calcium?
Calcium+hydrochloric acid = calcium chloride+ hydrogen the base for any equation is metal+acid=hydrogen+salt
A precipitate will be formed when an aqueous carbonic acid solution is added to an aqueous solution of?
Calcium chloride. When carbonic acid is added to a solution containing calcium chloride, a white precipitate of calcium carbonate is formed due to the reaction of calcium ions with carbonate ions from carbonic acid.
Can you use sulfuric acid to make nitrous acid?
No, it is not possible to convert sulfuric acid to nitrous acid.
How do you write nitrous acid in solution?
Nitrous acid in solution can be written as HNO2(aq).
Nitrous acid symbol?
The chemical formula (not symbol) of the nitrous acid is HNO2.
Which acid has the formula HNO2?
Nitrous acid has the formula HNO2. It is a weak acid that can be formed by dissolving nitrogen dioxide in water. Nitrous acid is known for its role in the nitrosation of amines.
Is formic acid stronger than nitrous acid?
No, nitrous acid is stronger. Nitrous acid pKa = 4.5 x 10^-4, while formic acid pKa - 1.7 x 10^-4.
What is the word equation between acid and metal carbonate?
metal carbonate + acid = metal salt + carbon dioxide + water e.g. calcium carbonate + hydrochloric acid = calcium chloride + water + carbon dioxide CaCO3 + 2HCl = CaCl2 + H2O +CO2
