What else can I help you with?
Why does calcium carbonate appears to get lighter when it reacts with acid?
Reacting with an acid calcium carbonate is transformed in another salt.
Is reacting calcium carbonate with hydrochloric acid endothermic or exothermic?
Reacting calcium carbonate with hydrochloric acid is an exothermic reaction. It releases heat energy as the reaction proceeds, making the surroundings warmer.
What acid makes ca(NO3)?
Calcium nitrate, Ca (NO3)2 can be formed by reacting nitric acid with calcium hydroxide or a basic calcium salt.
Does calcium react in acid?
Yes, calcium does react with acids such as hydrochloric acid to produce calcium chloride and hydrogen gas. This reaction is a common example of a metal reacting with an acid to form a salt and hydrogen gas as a byproduct.
What does Nitric acid plus calcium hydroxide yield?
An acid reacting with a hydroxide will result in the formation of water and the corresponding salt of the hydroxide's cation and the acid's anion. So in this case the products are water and calcium nitrate.
Calcium reacting with hydrochloric acid?
When calcium reacts with hydrochloric acid, calcium chloride and hydrogen gas are produced. The balanced chemical equation for this reaction is Ca + 2HCl → CaCl2 + H2. This is a single displacement reaction where the more reactive calcium displaces the hydrogen from hydrochloric acid.
Which pair of substances would most likely result in the production of a gas when reacting with an acid?
A metal carbonate (such as calcium carbonate) or a metal bicarbonate (such as sodium bicarbonate) would most likely produce a gas when reacting with an acid. This is because carbonates and bicarbonates release carbon dioxide gas when they react with acids.
A geologist tests a rock containing calcium oxide by reacting it with hydrochloric acid. Water and calcium chloride form. Which bonds break?
ca-o bonds in calcium oxide and h-cl bonds in hydrochloric acid
What is the word equation of calcium with hydrochloric acid?
One gram atomic mass of calcium reacts with two gram molecular masses of hydrochloric acid to form one gram formula mass of calcium chloride and one gram molecular mass of diatomic hydrogen gas.
What is the balanced equation for Solid calcium reacting with aqueous nitric acid?
Ca(s) + 2HNO3(aq) -> Ca(NO3)2(aq) + H2(g)
How does hydrofluoric acid dissolve bodies?
Hydrofluoric acid is a strong acid that can dissolve tissues and bones by reacting with the calcium in the body, forming soluble calcium fluoride. This process breaks down the body's structure, leading to tissue and bone dissolution.
How are super phosphates prepared?
Super phosphate is calcium dihydrogen phosphate. It can be prepared by reacting sulfuric acid with calcium phosphate :Calcium phosphate + Sulfuric acid ----> Calcium sulfate + Calcium dihydrogen phosphate3 Ca3(PO4)2 + 6 H2SO4 ----> 6 CaSO4 + 3 Ca(H2PO4)2
