Answer:

I believe you are asking about the objective lens or eyepiece.

Explanation:

Objective lenses are used to magnify objects enough for you to see them in great detail

Eyepiece/Ocular is what you look through at the top of the microscope.

A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. Both the eyepiece and the objective lens contribute to the magnification of the object.

The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.

N2 + 3 H2 --> 2 NH3
Anna71 [15]

Answer:

4 moles of NH3 will be produced

Explanation:

The reaction expression is given as:

            N₂  +  3H₂  →  2NH₃

We have to check that the equation of the reaction is balanced.

 Then;

      if 2 mole of N₂ reacts;

 1 mole of N₂ will react with 3 mole of H₂ to produce 2 mole of NH₃

2 mole of N₂ will react with (2x3)mole of H₂ to produce (2x2)mole of NH₃

                                                    6mole of H₂ to produce      4 mole of NH₃

uranmaximum [27]

Answer:

The use of phenol (carbolic acid) as a wound disinfectant was first practiced by Lister. The correct option is E

Explanation:

Phenol( carbolic acid) is an aromatic organic compound. It has the following properties:

- it's soluble in water

- it's a weak acid and

- highly reactive toward electrophilic aromatic substitution

In Medical field, phenol was first used as an antiseptic by Joseph Lister.Joseph Lister was a student at University College London under Robert Liston, later rising to the rank of Surgeon at Glasgow Royal Infirmary. He believed that patients who passed through surgery, died due to infections caused by microorganisms.He theorized that if germs could be killed or prevented, no infection would occur. Lister reasoned that a chemical could be used to destroy the micro-organisms that cause infection. He made use of the carbolic acid by soaking a clean cloth in them, and placing it over the surgical wounds of patients.
