D. I or Iodine

This is because they are both in the same periodic family (the halogens) and thus the number of valence electrons are the same

Answer: (4) I (iodine)

Explanation:

Reactivity of elements follow a trend in such a manner that elements in the same group have similar chemical properties since they react in similar ways during chemical reaction. This similarity is as a result of the same number of valence electrons they have in their respective outer shell. This particular similarity is what classifies them into groups.

In this question, Chlorine is in the same group with Iodine and they're referred to as "halogens" and all halogen have similar chemical reactions. Example, they seek one valence electron to be stable. Easy formation of salts with metals etc

What is the definition of to squeeze a gas into a smaller space
ollegr [7]
I think the best word here would be compress. It is to compress that is defined as to squeeze a gas into a smaller space. Compression is the reduction of volume which cause an increase in pressure of the gas. Hope this answers the question. Have a nice day.

what volume of a 0.138 m potassium hydroxide solution is required to neutralize 26.0 ml of a 0.205 m nitric acid solution?
Law Incorporation [45]

A neutralization titration is a chemical response this is used to decide the composition of an answer and what kind of acid or base is in it. This is a way of volumetric analysis and the formula is (M1V1 = M2V2).

Utilize the titration method of M1V1 = M2V2 in view that we're given the concentrations of every compound and the quantity of KOH. Let: M1 = 0.138M, V1 = x, M2 = 0.205M, V2 = 26.0 ML.

  • M1 = initial mass
  • V1= initial volume
  • M2 = final mass
  • V2= final volume
  • (M1V1 = M2V2)
  • (0.138)(V1) = (0.205)x(26.0)
  • V2=(0.205)x(26.0)\ 0.138
  • V2 = 47.10 M/L
  • The final value of Volume needed for neutralization of nitric acid solution is  V2 = 47.10 M/L
