Ca(s) + 2H2O ==> Ca(OH)2(s) + H2(g). This is because of the reactivity of calcium (as opposed to magnesium) so it forms the hydroxide. If it were less reactive, as is magnesium, it would form the metal oxide (if reacted with hot water or steam). Moving down group 2, the metals become more reactive.
What else can I help you with?
Calcium plus H2O equals Hydrogen?
Calcium and water react to form calcium hydroxide and hydrogen. Ca + 2H2O --> Ca(OH)2 + H2
What gas is given off when calcium is mixed with water?
The calcium metal will react with the water to form calcium oxide and give off Hydrogen gas.
What is the total number of moles of Ca needed to react completely with 4.0 moles of water?
The balanced chemical equation for the reaction between calcium and water is Ca + 2H2O -> Ca(OH)2 + H2. This means that 1 mole of Ca reacts with 2 moles of water. Therefore, to react completely with 4.0 moles of water, you would need 2.0 moles of Ca.
What happens when calcium react with nitric acid?
When calcium reacts with nitric acid, it forms calcium nitrate, water, and releases hydrogen gas. The balanced chemical equation for this reaction is: Ca + 2HNO3 -> Ca(NO3)2 + H2O + H2.
What is a word equation for the reaction of calcium and water?
Calcium + water gives hydydrogen gas plus Calcium ions in solution and hydroxide ions in solution.
Do hydrochloric acid react with calcium?
Yes. When most metals react with dilute hydrochloric acid, metal chloride and hydrogen gas are the products. In the case of calcium, calcium chloride and hydrogen gas are produced.
Will Sodium react with water and one of the products is H2?
Yes. Sodium will react vigorously with water. The reaction is very exothermic and may even cause fire. 2Na + 2H2O ---> 2NaOH + H2
What happens when you put calcium in water?
Calcium reacts slowly with water. The reaction forms calcium hydroxide, Ca(OH)2 and hydrogen gas (H2).
Can you have the result of this reactionCa plus H2SO4?
Ca + H2SO4 ----------> CaSO4 (s) + H2(g) calcium and Sulphuric acid react to form calcium sulphate and release hydrogen gas.
What is the word equation for the reaction of calcium with water?
The reaction is: Ca + 2H2O = Ca(OH)2 + H2
How many grams of calcium are required to react with 7.75 grams of water to produce calcium hydroxide and hydrogen gas?
To determine the amount of calcium needed, you need to balance the chemical equation for the reaction between calcium and water. The equation is Ca + 2H2O → Ca(OH)2 + H2. Then, convert the mass of water to moles, use the stoichiometry of the balanced equation to find the moles of calcium required, and convert that to grams of calcium.
What is the word equation of calcium react with water?
Similar to Sodium and Water. Efferevescence and an alkali product . Ca(s) + 2H2O(l) = Ca(OH)2 (aq) + H2(g). NB Where sodium is a Group '1' metal , it has only ONE hydroxide attached. Calcium is a Group '2' meta; , so it has TWO hydroxides attached.
