please science homework help?(cant find answer anywhere)?

Question

when you mix alkali and acid together what happens to the temerature? if you know please answer.thanks xxx

Answer 1

this produces a hot gas in the air so in other words the temperature rises

Answer 2

You get heat, and stuff expanding. Try mixing baking soda with vinegar. It's a classic alkali / acid reaction. Just make sure you do it in a big enough bowl to handle the volcano.

P.S. - it's an exothermic reaction if it gives off heat. It's endothermic if it absorbs heat.

Answer 3

Heat is produced or used up. It can either result in an endothermic reaction, whereby energy is used up to produce the product. Or it can result in an exothermic reaction where heat is produced. Exothermic reactions are more common when acids and alkalis are mixed together and result in increased temperatures.

Answer 4

Mixing an Alkali and Acid cause an endothermic reaction in which heat is produced and temperature rises.

Answer 5

it really is D. I initially concept A, yet in case you look it up in a dictionary or google "outline: Metabolism" it comes again with a ton of definitions that really say a similar as answer D. "The sum of all the chemical and actual changes that ensue in the body and enable its continued boost and functioning." "The sum of the chemical changes in residing cells which grant potential for the needed events and approaches of the body." "Metabolism is the set of chemical reactions that ensue in residing organisms with the intention to maintain existence. "

Answer 6

usually you get some heat and some nasty smelling gas -- depending on the stuff you are mixing... don't do this at home!

Answer 7

do your research at the library. your science book will help too.
