What else can I help you with?
Ask us of the following are true about centripetal force?
Sure! What are the following statements about centripetal force you would like to know if they are true or not?
What is a substance that speeds up a reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction.
What is a substance that speeds up a chemical process?
catalyst-by lowering activation energy
You can maintain a proper following distance by using the three second rule true or false?
True. The three-second rule helps you maintain a safe following distance from the vehicle in front of you. To do this, pick an object on the road ahead and when the vehicle ahead passes it, count "one thousand one, one thousand two, one thousand three." If you pass the object before you finish counting, you are following too closely.
Which of the following is not true of cause-and-effect relationships?
The effect occurs before the cause.
A catalyst for automobile exhausts removes carbon dioxide. True or False?
that is true
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
Which of the following acts as a catalyst in catalytic converters?
Metal
What is ture of a catalyst?
It is true that a catalyst is used in chemical reactions to help speed up the reaction by reducing activation energy.
Is it true that the effect of a catalyst on a reaction is to raise the activation energy?
No, it is not true that a catalyst raises the activation energy of a reaction. In fact, a catalyst lowers the activation energy, allowing the reaction to occur more easily and at a faster rate. By providing an alternative pathway for the reaction, catalysts facilitate the formation of products without being consumed in the process.
What causes molecules to change?
I think this refers to catalysts as these are considered not to be changed by a reaction-- sometimes this true when molecules react on the surface of a catalyst bu sometimes the catalyst does get involved in the chemical reaction- but is regenerated.
CFCs are the catalyst in the destruction of Ozone. true or false?
CFC's are catalysts. They fasten the rate of reaction.
What is a true of a catalyst?
The catalyst is not a reactant in a chemical reaction but contribute to the success of this reaction.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
Which of the following is true?
Hi
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
