Ok so we had a lab and my teacher is currently unavailable right now and im mildly confused. we put sodium hydrogen carbonate into a test tube over a flame and lit a splint and stuck it into the mouth of the test tube. we also had to stick a piece of cobalt chloride testing strip into the mouth as well ( to test for moisture and or water vapor) which there was. anyways, we have to come up with a chemical equation for this reaction and the best thing i can come up with is nahco3. i have no clue where to go from here if you can i greatly appreciate

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

The answer is 5 10 15
