How does a phenol red-containing solution look if co2 level is low?
vampirchik [111]

Answer:

The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.

Explanation:

is this correct

Give the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by the element. rb
devlian [24]

Actually Rb or Rubidium in zero state has the following electron configuration:

<span>1s22s2</span><span>2p6</span><span>3s2</span><span>3p63d10</span><span>4s2</span><span>4p65s1</span>

 

However we can see that the ion has a 1 positive charge, which means that it lacks 1 electron, therefore the answer from the choices is:

<span>d. rb+: 1s22s22p63s23p64s23d104p6</span>

An SN2 reaction is a type of ________in which the nucleophile attacks the electrophile _______a leaving group leaves.
mars1129 [50]

Answer:

Nucleophilic reaction

and

Explanation:

A nucleophilic reaction is a type of reaction that involves attack of a specie having a negative charge or a lone pair of electrons on a positive center. This negatively charged specie or specie having a lone pair of electrons is called a nucleophile.

An SN2 reaction is a bimolecular, concerted nucleophilic reaction that leads to inversion of configuration at the carbon center. The leaving group is the group that departs from the frontside of the molecule as the nucleophile attacks from the backside.

For a single H2 molecule, H2 → 2H, the dissociation energy is 4.52 eV. How much energy would have to be put in (in kJ) to dissoc
grandymaker [24]

Answer: 7.2418 x 10^-19 joules

Explanation:

1 eV equals 1.602 x 10^-19 joules

Then 4.52eV will be multiplied by the above value to give 7.2418 x 10^-19 joules which is the energy required to dissociate the hydrogen molecule
