Question 5: Causes of Molecular Shape (3 points)

Chemistry
1 answer:
Sonja [21]3 years ago
7 0

Answer:

A. VSEPR theory assumes each atom molecule has a geometry to help minimize the repulsion between the electrons within the valence shell of the central atom.

B. Repulsion determines the molecular shape as the electrons are negativley charged. The negativity makes the atoms spread out as much as possible.

C. Lone electron pairs have greater repelling effects as they are closer to the nucleus of the central atom unlike bonding pairs.

What are the reactants in the reaction? What are their properties? Perform a quick Internet search, if needed.
Helen [10]

The reactants in this reaction are sodium and chlorine. Sodium is a soft, silvery-white metal that is highly reactive. Chlorine is a poisonous greenish-yellow gas that has an odor and combines readily with other elements.

This might be the exact question so you might wanna rephrase it but good luck! :)))

What is the empirical formula for a compound composed of 0.0683 mol of carbon ( C ), 0.0341 mol of hydrogen ( H ), and 0.1024 mo
liubo4ka [24]

The empirical formula for a compound composed of 0.0683 mol of carbon ( C ), 0.0341 mol of hydrogen ( H ), and 0.1024 mol of nitrogen ( N ) is  C_2HN_3.

<h3>What is the empirical formula?</h3>

An empirical formula tells us the relative ratios of different atoms in a compound.

Given data:

Moles of carbon = 0.0683 mol

Moles of hydrogen = 0.0341 mol

Moles of nitrogen = 0.1024 mol

Dividing each mole using the smallest number that is divided by 0.0341 moles.

We get:

Carbon= 2

Hydrogen=1

Nitrogen=3

The empirical formula for a compound isC_2HN_3.

Which of these four contain an ionic bond, H2O, CO, P2O5, or AlCl3? i answered earlier and I was wrong.
bazaltina [42]
<span>I would say D AlCl3. covalent bonding is when 2 or more elements share electrons (usually when nonmetals bond with nonmetals) ionic bonding is when one element steals another's electrons (usually when nonmetals bond with metals)</span>
