These species contain certain atoms that will strongly prefer to be reduced/oxidized respectively, when taking part in a redox reaction.Answer and Explanation: Calcium is assumed to be present as the solid metal. The neutral atoms in the calcium metal contain 2 valence electrons and an oxidation...
If powdered elemental zinc and powdered elemental sulfur are poured into a metal beaker and then heated strongly, a very vigorous chemical reaction takes place, and the ___ zinc sulfide is formed. Iodine pentafluoride is an incendiary agent, a substance that ignites...
Generally, sodium, calcium salts in nature are available in the form of their carbonates. The presence of carbonate anion in the given sample can be identified by adding dilute HCl acid. This test releases the effervescence of CO2gas. Answer and Explanation: The reaction between...
If baking soda (sodium hydrogen carbonate) is heated strongly, the following reaction occurs: Calculate the mass of sodium carbonate that will remain if a 1.52-g sample of sodium hydrogen carbonate is heated. Sodium peroxide (Na_2 O_2) is used to...
Explain why the 1-bromobutane must be dried with anhydrous calcium before purifying it by fractional distillation. In recrystallization, why is it important to add the solvent to the solid, rather than the other way around? Why is cracking an important technological process?...
