Answer: The correct answer is metal and non-metal.

Explanation:

Elements are mainly divided into 3 classes in the periodic table.

1.) Metals: The element which lie on the left side of the periodic table are mainly metals. These elements loose electron easily and form positively charged species. These elements are present in the highest proportion in the periodic table.

2.) Non-metals: The elements which lie on the right side of the periodic table are considered as non-metals. These elements gain electrons easily and form negatively charged species.

3.) Metalloids: These lie between metals and non-metals and show the properties of both metals and non-metals.

Copper lie in the period 4 and group 11 of the periodic table and it can easily loose electron and hence, it is considered as a metal.

Chlorine lie in the period 3 and group 17 of the periodic table and it can easily gain electron and hence, considered as a non-metal.

Therefore, the correct answer is metal and non-metal.

What is the mass of 0.5 moles of carbon tetrafluoride, CF4?

VashaNatasha [74]

Answer:

44 g

Explanation:

The formula for the number of moles (n) is equal to $n=\frac{mass}{molecular weight}$ .

Since we need to find the mass, we derive it from the formula of the number of moles and we get that mass = n x molecular weight .

The molecular weight of $CF_{4}$ = 12 g/mol (from the carbon) + 19x4 g/mol (from the 4 fluorine atoms)= 88 g/mol

We plug in the numbers in the derived formula for the mass and we get :

mass = n x molecular weight = 0.5 mol x 88 g/mol = 44 g
