Compare the reactivity of alcohols with the length of the R-group.

Answers

Answer 1
Answer:

The longer the alkyl chain is, the lesser the reactivity of the alcohol and vice versa.

What are alcohols?

Alcohols are substances that possess the -OH functional groups. We know that the reactivity of the alcohol depends on the length of the alkyl group.

Now, the longer the alkyl chain is, the lesser the reactivity of the alcohol and vice versa. This is why the rate of reaction of high molecular weight alcohols is low.

Answer 2
Answer: As you increase the chain of a alcohol, the reactivity decreases. This is due to an increase in disorder and decrease in intermolecular attraction between molecules.

Acetone is a common solvent and has a density of 0.7899 g/mL. What volume of acetone, in mL, has a mass of 29.3 g?

Answers

V (volume), M (mass), D (Density)
We get: M = 29.3, and D = 0.7899, And V = ? 
The formula to find the volume is: 
V =  (M)/(D)
So we get:
V =  (29.3)/(0.7899)
V = 37.09

So, the volume of acetone when it have a mass of 29.3 grams is about 37.09 milliliters

Abdid is an astronomer who has been observing objects that orbit the Sun in the asteroid belt. He finds a previously undiscovered round, rocky object that is not similar in shape to the rest of the asteroids. What has Abdid most likely found?

Answers

Answer:

Abdid has most likely found a new dwarf planet.

Explanation:

Dwarf planets are too small to be considered planets, but are also two big to be considered something else. A dwarf planet has to have sufficient mass so that the self-gravity is strong enough to create its round shape. Other qualifications of a dwarf planet is that it has not cleared the neighborhood around its orbit and it cannot be a satellite. Based on the location, size, and shape of the object Abdid has discovered, it is likely he discovered a new dwarf planet in the asterioid belt. One of the most famous is Ceres.

since it is round and it is the asteroid belt it is most likely that he found a dwarf planet 

A rabbit is observed to have brown fur. This observed trait is referred to as the

Answers

The observed trait of the individual rabbitis referred to as the phenotype.

Organisms receive a set of genes from their parents. This set of genes that an organism receives from its parents is called the genotype of the organism.

However, genes occur in pairs called alleles. In a pair of alleles, one gene is dominant while other is recessive. The dominant gene determines the expressed traits of the individual organism.

This expressed trait of the individual organism as determined by the dominant gene is called the phenotype of the organism.

The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the(1) melting points of the elements in the compound
(2) densities of the elements in the compound
(3) electronegativities of the bonded atoms in a molecule of the compound
(4) atomic masses of the bonded atoms in a molecule of the compound

Answers

The correct answer is option 3. The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the electronegativities of the atoms in a molecule of the compound. Electronegativities of the atom tell how the electrons are distributed in the molecule.

What is the term for a solid substance that is composed of minerals?
