Answer: This reaction is called as Chemiluminescence. A type of reaction in which light is produced due to chemical reaction. While in case of Phosphorescence and Fluorescence light is emitted due to absorption of photons.
Explanation: i looked the answer up but your welcomee ❤
I think this is what u need.
1.<span>Cd(NO3)2 + 2NH4Cl -> CdCl2 + 2NO3NH4
2.</span>H3PO4(aq) + 3Ca(OH)2(aq) -> Ca3(PO4)2(aq) + 6H2O
When heating lithium carbonate (Li2CO3), it will dissociate to Li2O and Co2. So the balanced chemical equation of this reaction is Li2CO3 = Li2O + CO2.
I believe it is D. <span>Radiation is the only form of heat transfer that can travel through the vacuum of space.
