Choose all of the answers that are correct when describing this atom.
gregori [183]
I believe that this atom is  chlorine and the atom has an overall charge of zero.
Chlorine is chemical element which is atomic number 17 in the periodic table. Each chlorine atom has 17 protons (positively charged) in the nucleus balanced by 17 electrons (negatively charged) in the energy shells ( thus an overall charge of zero)

Which of the following describes a covalent bond?
BaLLatris [955]

I think it is C, because a covalent bond is a distribution of 2 atoms to 1 electron, meaning they are sharing and not exchanging, and the electronegravity would be above 1.7

HELP! THIS IS A TIMED QUIZ!!
ivanzaharov [21]

Answer:

A) Age!! Its because even if the object was 1 year old or 100 years old, nothing about the impact would change. However, those other categories depict features that would definitely make an impact. For example as object that is big, fast, and hits at an angle perpendicular to whatever it is moving towards, the impact will be very lage. But if its the opposite and it was small and slow, then the impact crater would not be as large. Good luck on your quiz!!

If you have a pH of 3.35, what is the hydrogen ion concentration of the solution?
melamori03 [73]

Answer: 4.46 x 10^-4M

Explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

On the pH scale, readings are from 1 to 14.

- pH values less than 7 are regarded as acidic. So, the solution with pH 3.35 is said to be acidic, and will produce hydrogen ions.

3.35 = -log(H+)

(H+) = Antilog (-3.35)

(H+) = 0.000446M

Place (H+) in standard form

(H+) = 4.46 x 10^-4M

Thus, the concentration of hydrogen ion in the solution with pH 3.35 is 4.46 x 10^-4M
