meaning:An acid is a chemical substance, usually a liquid, which contains hydrogen and can react with other substances to form salts. Some acids burn or dissolve other substances that they come into contact with.
Answer:
FIREWORKS : WHEN FIREWORKS EXPLODE THEY EXPEL SMOKE WHICH IS A FORM OF GAS AND THEY LIGHT UP WHICH IS ANOTHER CHEMICAL REACTION AND OF COURSE THE WHOLE FIREWORK GETS HOT ( Temperature rises )
Explanation:
you could see your reaction happens when original substance changes in color temperature formation produces light or gas in many other things
( besides it's original form! )
answer what changed from it's original form!
ex: baking a cake:
the cake change form ( rising ) due to heat ( rising temperature )
REACTION WAS:
- formation of precipitate ( solid to settle out of a solution )
- change I'm temperature to bake the cake
Extra:
you got this!
I hope I helped even just a little!
Answer:
Colloidal dispersion or emulsion
Explanation:
The colloid of a liquid in liquid (both dispersed phase and dispersion medium are liquids) is known as emulsion or colloidal dispersion.
We know that oil and water are immiscible liquids. In order to make them miscible we have have add emulsifying agents.
An emulsifying agent has a long non polar hydrocarbon chain (in general) and a polar head.
For example salts of fatty acids.
The polar head is hydrophilic and non polar tail is hydrophobic.
It causes the miscibility of the two polar and non polar liquids
