Explanation:
Answer: When a fire is burning, chemical energy is turned into visible energy in the form of light and thermal energy in the form of heat.
Explanation:
Explanation:
a chemical reaction that absorbs energy is known to be endothermic since heat is being taken in by the reaction. The value of the transition state would be 150 because you have to subtract the product's enthalpy and the reactant's enthalpy to obtain it. A positive value for the transition state also corroborates that the reaction is endothermic.
An example of a heterogeneous catalyst is a catalytic converter. A catalytic converter is an emissions control device that converts toxic pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction (oxydation or reduction).
Answer:
240g
Explanation:
Using the equation m=pV, where m=mass, p=density, and V=Volume
m=(6)(40)=240
m=240
