Answer:
there are Muslims i am also a Muslim
Explanation:
Answer:
Oxygen is oxidizing gent and itself get reduced while lead is reducing agent and itself get oxidize.
Explanation:
Chemical equation with oxidation state:
O⁰₂(s) + Pb⁰ (s) → Pb⁺⁴O₂⁻²(s)
Oxidizing agent:
Oxidizing agents, oxidize the other substance and itself get reduced. They can be identify by just looking the oxidation state. If oxidation state is decreased on the right side it means substance gain the electron and get reduced.
Reducing agent:
Reducing agents, reduce the other substance and itself get oxidize. They can be identify by just looking the oxidation state. If oxidation state is increased on the right side it means substance lose the electron and oxidation state increased.
In given chemical equation, oxygen and lead were in neutral form they react and form lead dioxide. In this product oxygen is oxidizing gent and itself get reduced and oxidation state change from 0 to -2 while lead is reducing agent, itself get oxidize and oxidation state change from o to +4.
Answer:
The correct option is;
True
Explanation:
Combustion is a chemical reaction between components of a combustion reaction which are;
1) A fuel
2) An oxidizing agent
The oxidizing agent or oxidant in a combustion reaction consist mainly of oxygen.
A combustion reaction is an oxidation and reduction (redox) heat evolving (exothermic) reaction that takes place at high temperatures and produces smoke which consists of gaseous mixture of chemicals and sometimes very small solid particles
An exothermic reaction can be classed either as rapid, spontaneous, or explosive
A spontaneous exothermic reaction is one that begins on its own in atmospheric conditions and room temperature as the heat required to begin the reaction is produced by the initial oxidation of the reacting fuel
Example of a substance that undergoes spontaneous oxidation reaction is white phosphorus.
Answer:
Explanation:
Hello,
In this case, the Boyle's is mathematically defined via:
Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:
We can compute the new pressure:
Which means the pressure is increased by a factor of four.
Regards.
