Answer:

C) Electrons will reside closer to chlorine, and the bond will be polar

Explanation:

Electrons tend to be closer or attracted to high electronegativity and sulfur has less electronegativity than chlorine. Therefore, electrons will reside closer to chlorine. To find out if it is polar or nonpolar, according to the electronegativity chart you can find online, you can see that the electronegativity of sulfur is 2.5 while the electronegativity of chlorine is 3.0. Because the difference between these two is a slight change, it would be slightly polar. So, the bond will be polar.

A scientist could use DNA as a molecular clock to do which of the following? (2 points)

ad-work [718]

Explanation:

-to determine how long ago two species of animals shared an ancestor

The molecular lock describes a method which utilizes mutation rates for DNA over time, to determine the divergence of two species sharing common ancestry,due to evolution. Along with genetic drift, selective mating and natural selection, evolution may occur within populations due to spontaneous heritable changes to DNA, called mutations, over time.

Further Explanation:

During reproduction, other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

The combustion of palmitic acid is represented by the chemical equation: C16H32O2(s) + 23O2(g) → 16 CO2(g) + 16 H2O(l) The magni

solniwko [45]

Answer:

The correct option is C

Explanation:

From the question we are told that

The reaction is

$C_{16}H_{32}O_2(g) + 23O_2(g) \to 16 CO_2(g) + 16 H_2O(l)$

Generally $\Delta H = \Delta U + \Delta N* RT$

Here $\Delta H$ is the change in enthalpy

$\Delta U$ is the change in the internal energy

$\Delta N$ is the difference between that number of moles of product and the number of moles of reactant

Looking at the reaction we can discover that the elements that was consumed and the element that was formed is $O_2$ and $CO_2$ and this are both gases so the change would occur in the number of moles
