Neutrons have a charge

neutrons have a neutral charge

Explanation:

What make them neutral. It means why do we say that they are neutral. The American polymath benjamin Franklin named the charges as positive and the negative. He did this because when one kind of charges are combined they increase their effect but when the same kind was mixed with the other charges the charges used to disapear or loss their strength . so it was clear that there are two types of charges and have got a methametical relation between them . He called them posive and negative charges analogous to positive and negative numbers because when negative numbers are added with the negative number we get a larger negative numbers and vice versa. So it means that every object that we can observe contain charge but of both kinds in same quantity so we call them neutral . so answer to that question would be that it has charge because charge is the fundamental property of particles but it has both +ve and -ve charges equal in magnitude so not any net charge is there on neutron it is in equilibrium.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

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.
