A reaction has a negative enthalpy change

Energy is added in order to break a chemical bond

A reaction takes place in water where the water increases in temperature

Upon reaction, the energy of the products is lower than the energy of the reactants

When holding ice in your hand, the ice melts and your hand becomes cold

During reaction, the energy of the system increases

Homework Answers

Answer #1

A reaction has a negative enthalpy change
that means energy is released
EXOthermic

Energy is added in order to break a chemical bond
ENDOthermic

A reaction takes place in water where the water increases in temperature
temperature of water increases that means energy is released from the reaction
EXOthermic

Upon reaction, the energy of the products is lower than the energy of the reactants
product has lesser energy that means energy is released
EXOthermic

When holding ice in your hand, the ice melts and your hand becomes cold
since ice melts it absorbs heat
ENDOthermic

During reaction, the energy of the system increases
product has more energy that means energy is added
ENDOthermic

1 In the absence of oxygen, cells consume glucose at a high, steady rate. When oxygen is added, glucose consumption drops precipitously and is then maintained at the lower rate. Why is glucose consumed at a high rate in the absence of oxygen and at a low rate in its presence? 2 In the following diagram showing the distribution of thermal energy in a population of substrate molecules, the energy thresholds indicated by numbers represent ...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
