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:
it is The total number of protons and neutrons is 15
The mass of Li2O : 104.58 grams
<h3>
Further explanation
</h3>
Given
3.5 moles of Li2O
Required
The mass
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mol(n) = mass(m) : MW(molecular weight)
Input the value :
mass = mol x MW Li2O
mass = 3.5 mol x 29,88 g/mol
mass = 104.58 g grams
mass = 2.957 g
The pressure reading increases.
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit vicinity over which that pressure is distributed. Gauge stress (also spelled gage pressure)[a] is the stress relative to the ambient pressure.

Answer:
The rate law may be determined only by experiment.
Explanation:
For a reaction, A + B ---> C, the rate law can only be determined from experimental data. Chemists determine the rate of reaction by carefully observing the changes in the concentration of species as the reaction progresses.
Hence, the rate law is not determined by inspection of the chemical reaction equation, it must be obtained from the experimental data, hence the answer given.
