All the given species have the same charge except peroxide.
<h3>Charges on ions</h3>
- The charge on monohydrogen phosphate is negative because of its formula,
.
- The charge on permanganate is negative. The formula is

- The charge of oxide (
) is negative.
- The charge on peroxide is ( R−O−O−R) is neutral.
- The charge on oxalate,
, is negative.
Thus, only peroxide is unique.

Answer:
Its existence was determined by an English scientist studying nature.
Its existence was established after the invention of the microscope.
Explanation:
I know because atoms are made up by a scientist study chemicals while trying to learn about atoms as well.
Answer:
the volume delivered by the pipette = 22.32 mL
Explanation:
To calculate this, let us first note that the density of water relates it weight and its volume (density = mass ÷ volume), hence we are going to use density to determine the volume.
Density of water = mass/volume = 0.997 g/ mL
mass = 22.25g
Density = 0.997g/mL
volume = ?

∴ the volume delivered by the pipette = 22.32 mL
<em>Please note that this calculation is based on the fact that the weight of the empty flask has been determined and canceled out.</em>
