Solution. Verified by Toppr. The chemical formula of calcium oxide is C a O. The molecule is formed by the calcium cation C a + 2 and the oxygen anion O − 2, which form an ionic bond. Was this answer helpful?
Dispose of as a neutral solution:2 Slowly add the waste calcium oxide to a large volume of water at the rate of about 5 g of calcium oxide to 100 mL of water (approximately 5%). As noted in 1 above, the calcium oxide should be added slowly because the reaction is exothermic. This will form a slurry of calcium hydroxide/calcium carbonate.
Calcium oxide is also known as lime and is most commonly used for many purposes. It can be used for pH correction of water or for its disinfection (with excess lime). More importantly, lime has been used for a very long time to produce calcium carbonate by reaction with carbon dioxide.
If 56 g of calcium oxide reacts with a certain amount of water (X g), a new compound with mass 74 g is ...
The edge length of a unit cell of NaCl crystal lattice is 552 pm. If the ionic radius of sodium ion is 95 pm. What is the ionic radius of chloride io
Chlorine gas reacts with red hot calcium oxide to give calcium chloride and oxygen gas. 2 C a O + 2 C l 2 r e d h o t − −−−−− → 2 C a C l 2 + O 2 ↑ Hence, option D is correct.
Calcium hydroxide, C a (O H) 2 has a lower solubility in water than some of the other Group II hydroxides (K s p = 4.0 × 10 − 6 at 25 ∘ C). At this temperature in a saturated solution of calcium hydroxide, determine the concentration of calcium ions?
Calcium oxide combines with water to form calcium hydroxide. Hence, it is a combination reaction. It is an exothermic reaction as a lot of heat liberate with hissing sound during the reaction.
Calcium + oxygen → Calcium oxide ... Formation of nitric oxide from nitrogen and oxygen is a _____ reaction.
