Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
What must be absorb before a chemical reaction can start by the reactants?
energy
What Activation energy play in a chemical reaction?
Activation energy tells you how much energy chemical reaction needs to start. Example paper wont suddenly start burning, but you need first to put some energy in paper, before that reaction starts.
Adding a catalyst increases reaction speed by?
Catalysts lower the activation energy required for a chemical reaction. Activation energy refers to the mininum amount of energy that the reactant particles must possess so that effective collisions between them (hence a chemical reaction) can occur.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
The heat of fusion for water is the amount of energy that must be absorbed for water to what?
Melt.
What must be added to a reactant to start a chemical reaction?
Either an energy source to start the reaction or a catalyst.
In calculating the heat given off by a reaction in a calorimeter you must account for heat absorbed by?
Water and the Calorimeter.
What is the difference between energy and activation energy?
Activation energy is the initial amount of energy required to initiate a a reaction where as the energy of reaction is the total amout of energy realeased or absorbed during the complete reaction which is also called as heat of reaction.
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
What must be absorb before a chemical reaction can start by the reactants?
energy
Why must food be absorbed?
Food must be absorbed so the body can get all the nutrients from the food.
What is the heat of fusion for water is the amount of energy that must be absorbed for water to?
Melt.
What is the least amount of players to start a soccer game?
11 players must start the game for each team.
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.
What must be absorbed for a solid to melt?
They must gather close together until they can't bunch anymore and then they start to melt because they ran out of space.
For a fission reaction to fail to be maintained as a chain reaction each fission must produce less than additional fission reaction(s).?
In a continuous chain reaction at a steady rate, which gives a steady power output from a fission reactor, every fission gives rise to another fission. This happens because in every fission 2 or 3 neutrons are produced, some are absorbed or lost, but if just one is captured by another fissionable nucleus, the chain reaction will continue.
