Explanation:
by doing the experiment
to test the hypothesis of the problems.
The 
describes the reducing agent in the reaction below.
→ 
Reducing agent is the species in which oxidation is takes place. Reducing agent is the species in which loss of electrons is takes place. In the above reaction bromine ion in left hand side of the reaction loss electron to become bromine atom. So, bromine ion is reducing agent.
Oxidizing agent is the species in which reduction is takes place. Oxidizing agent is the species in which gain of electrons is takes place. In the above reaction chlorine atom in right hand side of the reaction gain electron to become chlorine ion. So, chlorine atom is reducing agent.

Answer:
THE WORK YOU DO ON A MACHINE IS CALLED WORK INPUT
Answer:
<span>On a 10-fold dilution of a strong acid, the pH will increase.
Proof:
Lets take initial concentration of Acid as 10 M, So, as
pH = - log [H</span>⁺]
Putting value of [H⁺]
pH = - log (10)
pH = -1
After 10 fold Dilution, the concentration iwill be 1 M, So,
pH = - log [H⁺]
Putting value of [H⁺]
pH = - log (1)
pH = 0
So, with 10 fold dilution the pH increases.
<u>22.5 grams H2O</u> are formed when 13.5 grams of methane (ch4) burns in 40.0 grams of oxygen.
<h3>
What is methane?</h3>
Methane, colourless, odourless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. Its chemical formula is CH4.
<h3>
Where do methane emissions come from?</h3>
According to the EPA, globally, 50 to 65% of total methane emissions come from the following human-caused activities:
- Leaks from natural gas systems
- Landfills and waste from homes and businesses
