Why is it importana to have variables and untis included in a data table?

Ghella [55]

Because if they aren't properly included, it means that you are saying that the numbers can be anything, all reals.

Not including units is the same thing, if you don't properly lable the data table, you could be talking about anything.

Not giving a proper unit/variable is almost like giving someone permission to assume what you're talking about

Which statement is true about a reversible reaction?

bonufazy [111]

Answer:

The correct statement is : It results in an equilibrium mixture of reactants and products.

Explanation:

A reversible chemical reaction is one that occurs in both directions, that is, of the reagents to generate products and vice versa. In synthesis, they are incomplete reactions since the reagents are not consumed in their entirety, since the products react to generate them again.

Which two electron configurations represent elements that would have similar chemical properties? (1) 1s22s22p4 (2) 1s22s22p5 (3

Anton [14]

Answer: Two electron configurations of elements that would have similar chemical properties are (2) and (4).

Explanation:

(1) $1s^22s^22p^4$

(2) $1s^22s^22p^5$

(3) $[Ar]4s^23d^5$

(4) $[Ar]4s^23d^{10}^4p^5$

Valence electrons : These are the electrons present in last principal quantum number of an atom of the element.

Two electron configurations represent elements that would have similar chemical properties are (2) and (4). This is because number of valence electrons present in both of them are same that is seven valence electrons . Also valence electrons of both the elements are present in p-orbital which means that they both belongs to same group in a periodic table. The members of same group in a periodic table have similar chemical properties.
