In a chemical reaction, where is the catalyst located A. on the reactant side

B. on the product side

C. above the arrow

D. on both sides of the arrow

A. on the reactant side

Explanation:

A catalyst will appear in the steps of a reaction mechanism, but it will not appear in the overall chemical reaction

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
