Answer:
No, it acts only as a reducing agent
Explanation:
Sulphur dioxide is a strong reducing agent. It is mainly used to prevent dried fruit from being oxidised and discoloured.
Answer:
a)beta decay; to reduce the number of neutrons
Explanation:
When an isotope decays by beta decay, a neutron is converted into a proton, an electron and a neutrino (a particle that serves to balance spins). This process reduces the neutron/proton ratio.
During the beta decay of carbon-14, an atom of 14C decays into an atom of 14N. Hence the number of protons in the atom increases by one, creating a nitrogen atom.
Answer:
60km/H
Explanation:
The data were obtained from the question:
Distance = 150 km
Time = 2.5 hours
Speed =?
The speed of an object is simply the distance moved with time. It can be represented mathematically as:
Speed = Distance / Time
Speed = 150km/2.5 hours
Speed = 60km/H
The speed of the car is 60km/H
