Strontium compounds are often used in flares because their flame colour is bright red. One industrial process to produce low-solubility

strontium compounds (that are less affected by getting wet) involves

the reaction of aqueous solutions of strontium nitrate and sodium

carbonate. Write the balanced chemical equation, total ionic equa-

tion, and net ionic equation for this reaction.

The picture represents the process that produces most of the energy used by living organisms on earth. which process is represented in the picture? a) the magnetic attraction between two hydrogen nuclei. b) the fusion of hydrogen nuclei to produce a helium nucleus in the core of the sun. c) the fission of hydrogen nuclei to produce a helium nucleus in the core of the sun. d) the chemical reaction between hydrogen nuclei to produce a helium nucleus in earth's atmosphere.
