All the other answers have actually answered the question; “What compound contains calcium, carbon and oxygen?”… which of course could correctly be answered by CaCO[math]_{3}[/math]. The mechanism of oxygen production in photosynthesis remains unresolved, despite many studies. it has high elec­tric­i­ty and heat con­duc­tiv­i­ty; it boils at a tem­per­a­ture of 1484 de­grees Cel­sius. In order to identify whether a reaction is redox or not, you can write separate half equations that show how electrons are lost/gained. Include the state of matter of each species involved in the reaction. Then we place the cal­ci­um with potas­si­um ni­trate in the flame of the burn­er. The potas­si­um ni­trate breaks down into potas­si­um ni­trite and oxy­gen. The non-metal and oxygen gas (O 2) are the reactants in this type of reaction, and a non-metal oxide is the product. The presence of a calcium ion in the inorganic active site of the complex that produces oxygen is particularly puzzling, because the reaction is a redox process involving the transfer of multiple electrons, whereas calcium is redox inactive (it cannot transfer electrons under biological conditions). When calcium reacts with oxygen calcium oxide is formed by a highly exothermic reaction: 2Ca(s) + O2(g) → 2CaO(s) The reaction will be favored by enthalpy because of its exothermic nature; however, … Copyright © 2021 Multiply Media, LLC. The problem ask to show the reaction between the two elements which is calcium and oxygen to form an ionic compound. Alkaline earth metals also react with oxygen, though not as rapidly as Group 1 metals; these reactions also require heating. Reaction with water. As a source of oxy­gen, we will take potas­si­um ni­trate KNO₃. Ca is a soft met­al, which can eas­i­ly be cut with a knife; Cal­ci­um has a shiny sil­very-white col­or, which grows dull from the for­ma­tion of an ox­ide film when stored in­cor­rect­ly; it has a high melt­ing point – 842 de­grees Cel­sius.
