Is an example of an endothermic process Condensation Evaporating Burning or Freezing?
An example of an endothermic process is evaporating. Evaporation requires an input of energy to convert liquid water into water vapor, so it is an endothermic process.
Which of the following is endothermic a dry ice evaporating b a sparkler burning c the reaction that occurs in a chemical cold pack often used to ice athletic injuries?
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
What is the name of a substance formed by burning hydrogen and ethanol in air?
what is the substance formad when burning both hydrogen and ethanol in the air
What is the burning of substance called?

What is the burning substance of a substance?
The burning substance of a substance refers to the part of the substance that undergoes combustion or oxidation when exposed to heat or a flame. This process typically involves the release of heat, light, and often the production of new chemical compounds as the substance reacts with oxygen in the air.
