These models show the electron structures of two different nonmetal elements. Element 1 at left has a purple circle at center wi
Daniel [21]

Answer:

Element 2

Explanation:

If we look at the model stated for element 1, it is clear that element 1 must be a noble gas. It has eight electrons in its outermost shell this implies that it has already attained a complete octet of electrons and is reluctant towards chemical reaction.

The second element belongs to group 16 since it has six electrons on its outermost shell. It is certainly more reactive than element 1 which is a noble gas.

6. Calculate the molarity if 35.0 grams of KBr are dissolved in 700. ml?
olga55 [171]

Answer:

To calculate molarity, divide the number of moles of solute by the volume of the solution in liters. If you don't know the number of moles of solute but you know the mass, start by finding the molar mass of the solute, which is equal to all of the molar masses of each element in the solution added together.

Explanation:

try starting with 35.0 and dived it by the volume

Which of the following is one part of a chemical formula for a molecule?
solniwko [45]

D

Explanation:

An example is a chemical formula of a compound NH₄NO₃

These subscript numbers mean that there four (4) hydrogen atoms and three (3) oxygen atoms in the molecules.

A Lewis dot diagram for the molecule is used to show the electrons of the atoms, and their interactions – such as in covalent bonding- in the molecule
