Which way of representing a molecule best shows its three-dimensional shape?

1 answer:

5 0

The best way to show the three dimensional shape of a molecule is to use the space filling molecular model also called Calotte model. Calotte model is a type of three dimensional molecular model where atoms are arranged in such a way that atoms are represented by coloured spheres which take into account the radii of the real atoms. This model help the students to grasp the manner in which atoms and bonds are arranged in chemical compounds.

What are some ways that propane, butane, gasoline, diesel, and kerosene can be compared?

Whitepunk [10]

Answer:

Propane and butane are pure substances, which means that each one of them is made of only one type of molecule—propane molecules or butane molecules. In contrast, gasoline, diesel, and kerosene are not pure substances; they are mixtures of more than one substance.

What mass of magnesium oxide is formed when 48.62g of magnesium is reacted with excess oxygen?

marin [14]

Answer: -

81.03 g magnesium oxide is formed when 48.62g of magnesium is reacted with excess oxygen

Explanation: -

Atomic mass of Mg = 24 g

Molar mass of MgO = 24 x 1 + 16 x 1

= 40 g

The balanced chemical equation for this reaction is

2 Mg + O₂ → 2MgO

From the balanced chemical equation we see

2 mol of Mg gives 2 mol of MgO.

2 x 24 g of Mg gives 2 x 40g of MgO.

48.62 g of Mg gives $\frac{2 x 40 g MgO}{2 x 24 g Mg}$ x Mg

= 81.03g of MgO
