What is the three-dimensional shape of the molecule with this Lewis structure?

Answers

Answer 1

Answer:

Trigonal planar is the three-dimensional shape of the molecule with this Lewis structure. Hence, option C is correct.

What is an electron dot structure?

Lewis dot structures also called electron dot structures are diagrams that describe the chemical bonding between atoms in a molecule.

According to the Lewis structure of formic acid, the carbon atom is a central atom and it has three bond pairs without any lone pair of electrons. In VSEPR theory, the double bond is treated as one bond pair for the prediction of the shape of the molecule.

Hence, formic acid will have a trigonal planar geometry around the carbon atom and tetrahedral geometry around oxygen atom as it has two lone pair and two bond pairs

Hence, option B is correct.

Which substance, when dissolved in water, forms a solution that conducts an electric current?(1) C2H5OH (3) C12H22O11
(2) C6H12O6 (4) CH3COOH

Answers

Answer: Option (4) is the correct answer.

Explanation:

Substance which are able to conduct electricity are ionic in nature. This means that only ionic substances can conduct electricity because they dissociate into ions.

Therefore, out of the given options only acetic acid $(CH_(3)COOH)$ is ionic in nature.

$CH_(3)COOH \rightleftharpoons CH_(3)COO^(-) + H^(+)$

Though $CH_(3)COOH$ is a weak acid but it does dissociate into ions and hence, it forms a solution that conducts an electric current.

A chemist mixes two liquids together. The reaction produces a gas and a solid. According to the law of conservation of mass, what should the chemist observe when she compares the total masses of the substances before and after the reaction? A.The masses are equal. B.The masses are inconsistent. C.The mass of the substances before the reaction is greater than the mass of the substances after the reaction. D.The mass of the substances before the reaction is less than the mass of the substances after the reaction.

Answers

A is the answer. Because the masses are equal.

The answer is (A.) The masses are equal. (The law of conservation of mass says that mass cannot be created (added) or destroyed. So the total mass must be the same before and after. Hopefully, this helps)

What causes water molecules to be attracted to each other? A. Polar covalent bonds inside each water molecule
B. Hydrogen bonds inside each water molecule
C. Ionic bonds between water molecules
D. Nonpolar covalent bonds between water molecules

Answers

Answer:

Both polar covalent bonds inside each water molecule and hydrogen bonds inside each water molecule are liable for attraction between water molecules.

Explanation:

Water is a polar protic molecule.
Due to large difference in electronegativity between oxygen and hydrogen atom, two O-H bonds in water molecule are polar.
Due to the presence of polar covalent bonds in water molecule, water molecules attract each other through oppositely polarized ends.
In water molecules, H atom is attached with highly electronegative oxygen atom. Hence hydrogen bonding interaction arises between water molecules.
So, both option (A) and (B) are correct

This polarity makes water molecules attracted to each other. The oxygen-hydrogen bond in the alcohol molecule is also polar. But, the carbon hydrogen bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared more or less evenly.
