Which of the following species contains manganese with the highest oxidation number?
ioda

In NaMnO₄, Mn has the highest oxidation number.

The question is incomplete, the complete question is;

Which of the following species contains manganese with the highest oxidation number?

A) Mn

B) MnF₂

C) Mn₃(PO₄)₂

D) MnCl₄

E) NaMnO₄

In order to ascertain the specie that contains manganese with the highest oxidation number, we must calculate the oxidation number of manganese in each of the species one after the other.

1) For Mn, the oxidation number of Mn is zero because the atom is uncombined.

2) For MnF₂;

Mn has an oxidation number of +2

3) For Mn₃(PO₄)₂

Mn has an oxidation number of +2

4) For MnCl₄

Mn has an oxidation number of +4

5) For NaMnO₄

Mn has an oxidation number of +7

Hence in NaMnO₄, Mn has the highest oxidation number.

Chlorine gas reacts with aluminum metal producing aluminum chloride. What mass of chlorine reacts with 9.00g of Al to form AlCl3
Anit [1.1K]
The  mass of  chlorine   that react  with  9.00 g  of Al to form AlCl3  is   35.465  grams

     Explanation
write  the equation  for  reaction
that is
2 Al +  3 Cl2  = 2 Al CL3
find  the moles  of    Al  reacted

moles = mass/molar mass

  9 g/ 27  g/mol = 0.333  moles  of Al

by use  of mole ratio between   Al to  Cl2    which is  2:3   find the moles of  Cl2

mole  of cl2 =  0.333 x3/2 = 0.4995  moles


mass of  Cl2  is therefore =  moles  x  molar mass

= 0.4995  x71 =  35.465  moles

How many bacteria can fit into an animal cell
melisa1 [442]
The size of most eukaryotic animal cells range from 1 - 30 micrometers while the size of, let's say coccus bacteria is between 0.5 - 1.0 micrometers. So, if the largest animal cell is filled with the largest coccus bacteria, we can say that 30 bacteria can fit inside.
