an outside agent that effects the speed or occurance of a reaction is called a catalyst.A catalyst just speeds up a reaction but doesn't take part in the reaction itself.
Zn alone is a reducing agent because it donates electrons during a reaction and H2SO4 alone is an oxidizing agent because it may donates atomic oxygen during the reaction but (Zn + H2SO4) mixture is a reducing agent because this mixture may produce atomic hydrogen during a reaction.

It is safer to claim it as neither - not least because the reaction would/does not work. Far safer to say that the sulphur is oxidised (which, you could argue, makes it a reducing agent).
The term oxidation is named after oxygen, which is the most common oxidizing agent. Oxygen has a strong attraction for electrons, and in most chemical reactions it will take two electrons away from another atom (or from two atoms, such as in the case of the famous water molecule which is composed of one oxygen atom and two hydrogen atoms). So when an atom loses one or more electrons, it is oxidized.
An outside agent that affects the speed or occurrence of a reaction is called a catalyst. Catalysts work by providing an alternative reaction pathway with lower activation energy, allowing the reaction to happen more quickly. They are not consumed in the reaction and can be used repeatedly.
No it is not. Propane can be used as fuel during oxidation reaction however it is not an oxidizing agent. In a redox reaction such as combustion, propane acts as a reducing agent. Common agents are O2 and O3.
The higher the concentration of the oxidizing agent, the faster the oxidation rate, and the faster the reaction rate will be, and vice versa.

This is oxygen.
A reducing agent also known as reducer or reductant is the element or compound in oxidation reduction reaction. The reaction donates an electron to other species.
Zn alone is a reducing agent because it donates electrons during a reaction and H2SO4 alone is an oxidizing agent because it may donates atomic oxygen during the reaction but (Zn + H2SO4) mixture is a reducing agent because this mixture may produce atomic hydrogen during a reaction.

Frustration.
The story occurrence at Owl Creek bridge is ironic because it is a small incident in a big war. In the story, Peyton was captured and hanged as an agent and spy.
