What is the chemical symbol for platinum oxide?
Platinum dioxide, also known as Adams' catalyst, is usually represented as platinum(IV) oxide hydrate, PtO2-H2O. It is a catalyst for hydrogenation and hydrogenolysis in organic synthesis. This dark brown powder is commercially available. The oxide itself is not an active catalyst, but it becomes active after exposure to hydrogen whereupon it converts to platinum black, which is responsible for reactions.
Use catalyst in a sentence?
A catalyst is a substance that causes or aids in any type of reaction. Here are some sentences.That enzyme words as a catalyst in your body.She was the catalyst that started the argument.A catalyst is needed to make this chemical reaction occur.
What substance increases the rate of a reaction but is not itself changed by the reaction?
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).
Can you write a sentence using catalyst?
I don't know what a catalyst is. (That's my sentence XD)

What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
Which does a catalyst not change?

what is the purpose of catalyst in textile paint?
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.

What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.
