Indicators of a chemical reaction:
-turned pick (change of color)
-cold (change in temp)
-turned pick (change of color)
-cold (change in temp)
Indicators of a chemical reaction:
-turned yellow
-burning hot
-bubbling
-turned yellow
-burning hot
-bubbling
Conclusion:
1) The chemical changes in the first mixture was a change of color to pink and a decrease in temperature.
2) The chemical changes in the second mixture was a change of color to yellow, bubbling, and an increase in temperature.
3) There are many instances when gas can signal a chemical reaction because gas can be released in a chemical reaction.
4) It is endothermic because it observes it and the temperature drops
