Which of the following chemical reactions is the only reaction shown that would be predicted to occur based on the activity seri
Novosadov [1.4K]

B. Mn + NiBr₂  →  Ni + MnBr₂

Explanation:

The reaction that can be predicted of all is Mn + NiBr₂  →  Ni + MnBr₂.

The activity series is used to predict the products of single displacement reactions.

The series ranks metals in order of their reactivity. Those higher up in the series are highly reactive metals. Those at the bottom are slightly to non-reactive metals.

For a single displacement reaction to occur, a metal higher up in the activity series displaces one that is lower in the series.

  Reaction A will not occur, Ba is higher in the series

  Reaction C will not occur, Pt and Au are unreactive

  Reaction D will not occur as Zn is lower in the series

Mn is higher in the reactivity series and it will displace Ni from the solution.

What is true about elements that are in the same column group or family
shusha [124]

The given question is incomplete. The complete question is:

Which is true of Elements on a periodic table in the same group (family)?

A; Elements in the same family have similar chemical properties because they have the same number of electron shells.

B; Elements in the same family have similar chemical properties because they have the same number of valence electrons.

C; Elements in the same family have few similar properties as they have different numbers of electron shells.

D; Elements in the same family are always the same type of Elements and have the same number of protons.

Answer: B; Elements in the same family have similar chemical properties because they have the same number of valence electrons.

Explanation:

Elements are distributed in groups and periods in a periodic table.

Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons. The chemical reactivity of elements is governed by the valence electrons present in the element.

Example: Flourine, chlorine and bromine are elements which belong to Group 17. They have 9, 17 and 35 electrons respectively and contain 7 valence electrons each and need one electron to complete their octet.

Give the answer to the problem below using the correct number of significant digits. (1.3 x 103) x (5.724 x 104)
Gemiola [76]
(133.9) x (595.296)= 79,710.1344
Answer with significant digits: 80,000
1.3 has two significant digits so 79,700 rounds up to 80000.
