Answer:

Platinum is a Heterogeneous catalyst

Explanation:

Catalyst are substance that speed up the rate of a chemical reaction . Catalyst increases the rate of a chemical reaction by lowering it activation energy. During the reaction, the catalyst are not consumed. In other words, catalyst does not change in amount as it does not go into the reaction.

Catalyst can be homogeneous or heterogeneous . A homogeneous catalyst is one which phase(liquid or gas) is same as the reactant phase. Heterogeneous catalyst are catalyst which phase(solid) is different from the reactants phase.

From the reaction above

2H2O(aq) Pt(s)→ 2H2O(l) + O2(g)

Platinum is at the solid phase which is a different phase from the reactant(Hydrogen peroxide) which is Aqueous.

Since platinum is of a different phase , it is a heterogeneous catalyst.

Answer:

Heterogeneous

Explanation:

The catalyst, Pt, is not in the same phase as the reactants, i.e. it is solid, whilst the hydrogen peroxide is aqueous.

Which one of the following statements is FALSE? a In a neutralization reaction, an acid reacts with base to produce a salt and H

pishuonlain [190]

Answer: Option (c) is the correct answer.

Explanation:

HF is a weak acid and not a strong acid. This is because fluorine is a highly electronegative atom and when it combines with a hydrogen atom then it will attract the valence electron of hydrogen atom more towards itself.

As a result, it will not dissociates easily to give hydrogen ion. Hence, it acts as a weak acid.

A neutralization reaction is defined as a reaction in which an acid reacts with a base to give salt and water. For example, $HCl + NaOH \rightarrow NaCl + H_{2}O$

It is true that, spectator ions "appear in the total ionic equation for a reaction, but not in the net ionic equation".

Titration is defined as a process in which concentration of an unknown solution is determined using a solution of known concentration.

Thus, we can conclude that the statement HF, HCl, and HNO3 are all examples of strong acids, is false.

The electrolyte of the following is:

ozzi

An electrolyte is a term used to describe a compound that can dissociate into ions as it is nothing but an ionic compound, a salt made up of a positively charged cation and negatively charged anion.

Here the correct answer is D. Since there are no hydrocarbons or any other organic compound, that do not possess partial let alone full charges, all of them can dissociate in solution to give their ions.

This allows for the solution to be able to conduct electricity.

Why is it important for the pH of blood to remain constant?

lesya692 [45]

It is important for the pH of blood to remain constant because your blood would ionize and burn up if the pH wasn't constant. And if the pH was too high, bacteria ( good and bad, and foreign) would end up dying, as well as yourself.

It is easier to determine the electron configurations for the p-block elements in periods 1, 2, and 3 than to determine the elec

andreyandreev [35.5K]

Answer:

See Explanation

Explanation:

Because you have to get through the d-block electron configurations for the rest of the p-block elements which is a hassle to do. You need to know how to account for electron stability, from which subshell to remove electrons, etc. because it is all weird for d-block.
