Jamie completes the following steps in an experiment to investigate how temperature affects how fast something will rust in wate

r. He places a nail in a bowl of water in the sun and a nail in a bowl of water in the shade. He also leaves an iron nail out of the water in a dry bag out of the sun. Why would Jamie leave one out of the water and out of the sun?
A Jamie also wants to test if the water affects how fast the iron nail will rust.
B Jamie notices that the size of the nail is different, so he does not want to use it later.
C Jamie doing all these steps to create a control group to compare his results to.
D Jamie puts the nail in a cooler place to see if it will rust as fast as the other items.

As a race car races around the track, friction between the tire and the road heats the air in the tires and the pressure inside
kipiarov [429]
I believe the correct answer from the choices listed above is option B. The best explanation for this happening would be that air <span>particles speed up and collide with the tire walls more often. As the particles are heated, kinetic energy increases. Hope this answers the question. Have a nice day.</span>

In the reaction between bromine and sodium, a bromine atom gains an electron. What ion is formed? Is the bromine oxidized, or is
SVETLANKA909090 [29]

Answer: The ion formed after the reduction of bromine is Br^-

Explanation:

The electronic configuration of Sodium (Na) = [Ne]3s^1

The electronic configuration of Bromine (Br) = [Ar]3d^{10}4s^24p^5

From the above configurations, Sodium ion will loose 1 electron in order to gain stable electronic configuration and that electron is accepted by the Bromine atom because it is 1 electron short of the stable electronic configuration.

Na\rightarrow Na^++e^-   (oxidation reaction)

Br+e^-\rightarrow Br^-   (Reduction reaction)

Bromine atom is reduced to form Br^-

Reduction reactions are the reactions in which the element gain electrons.

Oxidation reactions are the reactions in which the element looses its electrons.

What is the molarity of a solution in
lana66690 [7]

Answer:

1.52M in NaCl

Explanation:

Molarity = moles solute / volume solution in Liters

=> molarity (M) = 3.8 moles / 2.5 Liters solution = 1.52 molar solution in NaCl

What is the predominant intermolecular force in the liquid state of each of these compounds: hydrogen fluoride (HF), carbon tetr
telo118 [61]

Answer:

HF - hydrogen bonding

CBr4 - Dispersion

NF3 - Dipole-dipole

Explanation:

Hydrogen bonding occurs when hydrogen is covalently bonded to a highly electronegative atom such as fluorine, chlorine nitrogen, oxygen etc. Hence the dominant intermolecular force in HF is hydrogen bonding.

CBr4 is nonpolar because the molecule is tetrahedral and the individual C-Br dipole moments cancel out leaving the molecule with a zero dipole moment hence the dominant intermolecular force are the dispersion forces.

NF3 has a resultant dipole moment hence the molecules are held together by dipole-dipole interaction.
