Answer:
a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.
b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.
c = The reaction which involve the oxidation reduction are called redox reaction.
The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.
Explanation:
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Chemical equation:
Zn + 2H⁺ → Zn²⁺ + H₂
a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.
b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.
Redox reaction:
The reaction which involve the oxidation reduction are called redox reaction.
The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.
Answer:
tantalum
i hope this helps<33 :)))))
Ideal gas is defined as hypothetical gas that fits all the assumptions of the kinetic-molecular theory. There are several assumption statement that apply to the behavior of an ideal gas, First Gases consist of larger number of tiny particles that are far apart relative to their size, Second, collisions between gas particles and between particles and container walls are elastic collision, third, gas particles are in rapid, random motion and continuous, Fourth, the temperature of a gas depends on the average kinetic energy of the particles of the gas.
Explanation:
oxidation is adding of oxygen and removal of hydrogen.
Reduction means removal of oxygen and addition of hydrogenm
