Calcium (Ca) does react with water at room temperature, although the reaction is not as vigorous as that of more reactive alkali metals. When calcium is added to water, it forms calcium hydroxide and hydrogen gas. The reaction can produce bubbles of hydrogen, which can ignite if the heat generated is sufficient. Overall, while the reaction occurs, it is relatively mild compared to other metals in the same group.
What else can I help you with?
Which metals does not react with water?
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
Which was does not react with cold water Ca or Mg or Sr or Ba?
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
What percentage of superphosphate is normally water soluble?
The solubility of Ca(H2PO4)2·H2O is approx. 20 g/L at approx. room temperature.
What is the diffusion coefficient of calcium in water?
The diffusion coefficient of calcium ions (Ca²⁺) in water at room temperature (around 25°C) is approximately 7.6 x 10⁻⁶ cm²/s. This value can vary slightly depending on factors such as temperature and ionic strength of the solution. The diffusion coefficient is a measure of how quickly calcium ions can spread out through water under diffusion processes.
How many moles of water are needed to exactly react with 2.0 moles of Ca?
To determine how many moles of water are needed to react with 2.0 moles of calcium (Ca), we first need to consider the chemical reaction between calcium and water. The balanced equation is: [ \text{Ca} + 2 \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 + \text{H}_2 ] From the equation, 1 mole of calcium reacts with 2 moles of water. Therefore, for 2.0 moles of calcium, you would need ( 2.0 , \text{moles Ca} \times 2 , \text{moles H}_2\text{O}/\text{mole Ca} = 4.0 , \text{moles H}_2\text{O} ). Thus, 4.0 moles of water are required.
Will a reaction take place if Ca H2O?
Yes. The reaction would be Ca + H2O --> Ca(OH)2 + H2. Hope that helped.

How do you know if ice cubes reach room temperature?
You can tell if ice cubes have reached room temperature by observing if they have completely melted. Once they have melted, the water will reach room temperature. Placing a thermometer in the water can also confirm if it has reached room temperature.
Which was does not react with cold water Ca or Mg or Sr or Ba?
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and 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.
Suggest 2 observations when Ca reacts with water?
The reaction is:Ca + 2 H2O = Ca(OH)2 + H2- hydrogen gas is released- the reaction occur at room temperature
What percentage of superphosphate is normally water soluble?
The solubility of Ca(H2PO4)2·H2O is approx. 20 g/L at approx. room temperature.
What percentage of superphosphate is normally water soluble in 24 hours?
THe solubility of Ca(H2PO4)2·H2O is 20 g/L at approx. room temperature.
What do HNO3 and CaOH23 make?
Nitric acid (HNO3) and calcium hydroxide (Ca[OH]2) react to form calcium nitrate (Ca[NO3]2) and water (H2O).
Does calcuim oxide react with cold water?
Yes it does react. It forms Calcium hydroxide and makes the water hot. It is because the reaction between CaO and water is an exothermic reaction
What is the highest water temperature of lake arrowhead ca?
69 degrees
Calcium plus H2O equals Hydrogen?
Calcium and water react to form calcium hydroxide and hydrogen. Ca + 2H2O --> Ca(OH)2 + H2
