1 ) Cobalt(II) nitrate react with nitrate zinc(II) to produce cobalt(III)-zinc oxide, nitrogen dioxide and oxygen
2Co(NO3)2 + Zn(NO3)2 → Co2ZnO4 + 6NO2 + O2
2) Calcium hydroxide react with phosphoric acid to produce calcium, hydrogen phosphate and water
Ca(OH)2 + H3PO4 → CaHPO4 + 2H2O
3) Copper(II) dichromate will react with Iron(III) arsenate to form Copper(II) Arsenate and Iron(III) dichromate
3Cr2CuO7 + 2AsFeO4 → Cu3(AsO4)2 + Fe2(Cr2O7)3
Reaction Type
: Double Displacement
4) aluminium hydroxide and hydrochloric acid react to form aluminium chloride and water
Al(OH)3 + 3HCl → AlCl3 + 3H2O
a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
Explanation:
A transverse wave is a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
A wave is a disturbance that transmits energy from one place to another.
There are two major types of waves:
- Transverse waves are waves that are propagated perpendicularly to the direction of the wave.
- A wave in string going up and down is a transverse wave.
- Electromagnetic waves are transverse waves.
- Seismic s-waves are transverse waves.
- Sound waves are longitudinal waves propagated parallel to their source.

Answer:
A Standard Hydrogen Electrode is an electrode that scientists use for reference on all half-cell potential reactions. The value of the standard electrode potential is zero, which forms the basis one needs to calculate cell potentials using different electrodes or different concentrations. It is important to have this common reference electrode, just as it is important for the International Bureau of Weights and Measures to keep a sealed piece of metal that is used to reference the S.I. Kilogram.
