Questions Asked in NEET exam
- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Concepts Used:
Antimicrobials
Infections and diseases may be caused by different types of organisms like bacteria, fungi, and viruses, etc., in humans and animals. Antimicrobial agent is the drugs that are used to prevent the pathogenicity of microorganisms.
Examples: Antibiotics, antiseptics, and disinfectants.
It is used to prevent infections and diseases caused by pathogens. Different types of antimicrobial drugs are commonly available. These are as follows:
- Antibacterial drug: is a drug that are used to inhibit the pathogenic activity of bacteria. Example: Zithromax.
- Antifungal drug: A drug that is used to prevent the fungal activity in the host is called an antifungal drug. Example: Miconazole
- Antiviral agent: A drug which is used to stop the pathogenic action of a virus is called as antiviral agents. Example: Tamiflu.
- Antiparasitic drug: is a drug that are used to prevent the growth of pathogenic parasites. Example: Anthelmintics
