What are differences between endothermic and exothermic reactions examples?
The main differences between exothermic reactions and endothermic reactions are: Exothermic reactions are reactions that give off energy (light, electrical or mainly heat), causing the surroundings to warm up. Endothermic reactions are reactions that absorb energy, causing the surroundings to cool down. The products of an exothermic reaction have less energy, or less total enthalpy, than of it's reactants. This is due to the reactants containing more stored energy because energy from external sources is not required. This also gives the products more stability because in order to achieve a reversible reaction and break the chemical bonds of the products, you will need to apply more energy to it. The opposite is for endothermic reactions. The products of the reaction have a greater total enthalpy of the reactants, causing the reactants stored energy to decrease. This produces less stable products that need less energy to break their bonds in a reversible reaction. Finally most exothermic reactions are spontaneous, where as most endothermic reactions are not spontaneous as they generally need energy applied to them before they start.
Are the saturated products formed from the addition reactions of unsaturated hydrocarbons more stable or less stable than the initial reactants?
The saturated product formed from the addition reactions of unsaturated hydrocarbons are more stable than the initial reactants.In general any chemical reaction that does not involve the input of vast amounts of energy to achieve (eg the smelting of ores) will produce products that are more stable than the reactants.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
Why are the products of nuclear fusion slightly less massive than the reactions?
The products of nuclear fusion are slightly less massive than the mass of the reactants because some of the mass of the reactants is converted into nuclear binding energy to hold the fusion product together.
What is chemical reaction that gives off heat called?
Exothermic reactions give off heat.
Why would a chemical reaction stop?
Reactions stop because after time there are less reactants so the chemical reaction starts to slow down. As there are less and less reactants the chemical reaction gets slower and slower until it stops.

What is the best term to describe a chemical reaction in which the reactants have less potential energy than the products?
A chemical reaction whose reactants have less potential energy than the products would be called an endothermic reaction.
What is the meaning of broad substrate specificity?
It is the opposite of narrow substrate specificity. Broad substrate specific reactions are 'less-picky' in their selection of co-chemical-reactants.

The saturated product formed from the addition reactions of unsaturated hydrocarbons are more stable than the initial reactants.In general any chemical reaction that does not involve the input of vast amounts of energy to achieve (eg the smelting of ores) will produce products that are more stable than the reactants.
What is to the left in a chemical equation?
By convention, the reactants are to the left and the products are to the right. For equilibrium equations, since the reaction goes both ways it's more or less arbitrary.
How could you determine if the products of cellular respiration have less chemical potential energy than the reactants?
I lost you at how
At equilibrium the total amount of the products is what?
may be equal to, greater than, or less than the total amount of the reactants. (:
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
Why are endothermic reactions rare?
Chemical reactions occur spontaneously when the free energy of the product is less than the free energy of the reactants. Free energy is a combination of thermal energy (heat) and entropy. If thermal energy is absorbed during a reaction, there must be an exceptionally large increase in entropy to give a net reduction in free energy.
Why are the products of nuclear fusion slightly less massive than the reactions?
The products of nuclear fusion are slightly less massive than the mass of the reactants because some of the mass of the reactants is converted into nuclear binding energy to hold the fusion product together.
Which family on the periodic table is less likely into enter the chemical reactions?
The noble gases.
