Ca(s) + 2H 2 O(l) → Ca(OH) 2 (aq) + H 2 (g) The reaction of calcium with water is less violent So, the heat released is not sufficient for the hydrogen to catch fire Calcium starts floating because the bubbles of hydrogen gas which are formed during the reaction stick to the surface of the calcium metal and hence calcium floats on waterOther cancers can increase the calcium level in blood by means not yet fully understood Bone disorders: If bone is broken down (resorbed) or destroyed, calcium is released into the blood, sometimes causing hypercalcemia In Paget disease, bone is broken down, but the calcium level in blood is usually normalHypercalcemia (High Level of Calcium in the Blood)2023年9月23日 Hypercalcemia is a condition you have when your blood has abnormally high levels of calcium Drink lots of water Switch or stop diuretic medications Stop taking calciumrich antacid tabletsWhat to Know About Hypercalcemia WebMDCaesium explodes on contact with water, quite possibly shattering the container Caesium hydroxide and hydrogen are formed Summary of the trend in reactivity The Group 1 metals become more reactive towards water as you go down the Group Explaining the trend in reactivity Looking at the enthalpy changes for the reactions The overall REACTIONS OF THE GROUP 1 ELEMENTS WITH WATER
