In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What does a positive H look like on a potential energy diagram?
The potential energy of the products is greater than the potential energy of the reactants.
When balancing a chemical equation what do the reactants need to be balanced with?
When balancing a chemical equation the reactants need to be balanced with the non-reactants. If you don't the formula will be produce negative results and you'll get the wrong answer.
What is the name of the energy needed to lift reactants from the energy trough?
This is called: Activation energy (abbrev. Ea)
Which of these is a rectant in photosynthesis?
CO2+H20 are the reactants, with the help of light energy these will produce glucose and oxygen.
Does an exergonic reaction become hot?
An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic). An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic).
What 2 reactants are required for cellular respiration?
There are no 2 specific reactants. Many reactants can 'produce' energy. Gasoline, methane, ethane, propane, butane, etc all burn with a variety of oxidizers (oxygen it self being only one of them) and release heat energy.
What problems must be overcome before fusion can be used to produce energy?
achieving high temperatures and containing the plasma reactants
Reactants and products in an energy diagram?
Activation energy is the distance from the reactants to the top of the "hill."
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
How do the reactants of photosynthesis differ from the reactants of chemosynthesis?
Both photosynthesis and chemosynthesis are processes by which organisms produce food. The difference between the two are the energies it use. Photosynthesis makes use of solar energy, while chemosynthesis makes use of chemical energy.
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What do you call a substances used up in a reaction?
Reactants. Reactants react to produce products.
Do endothermic reaction have reactants with more energy than its products?
Kinetic energy has more energy than products.
The name and symbol for internal heat of a system at constant pressure?
Energy, E.There are two types of chemical reactions. Reactions which produce energy are called exothermic reactions, while reactions which consume energy are called endothermicreactions. Generally, an exothermic reaction can be written such as Reactants → Products + Energy An endothermic reaction can be written such as: Reactants + Energy → Products
Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
