Step 1: Identify the substances.
Antibiotics are substances used to kill or inhibit the growth of bacteria.
Streptomycin, chloromycin, and penicillin are antibiotics.
Step 2: Analyze the options.
Aflatoxin is a toxin produced by fungi, not an antibiotic. Streptomycin, chloromycin, and penicillin are all used to treat bacterial infections.
Conclusion: The correct answer is (D) Aflatoxin.
Match the antibiotics in Group I with the microorganisms that produce them in Group II.
Calculate the EMF of the Galvanic cell: $ \text{Zn} | \text{Zn}^{2+}(1.0 M) \parallel \text{Cu}^{2+}(0.5 M) | \text{Cu} $ Given: $ E^\circ_{\text{Zn}^{2+}/\text{Zn}} = -0.763 \, \text{V} $ and $ E^\circ_{\text{Cu}^{2+}/\text{Cu}} = +0.350 \, \text{V} $
Find the values of a, b, c, and d for the following redox equation: $ a\text{I}_2 + b\text{NO} + 4\text{H}_2\text{O} = c\text{HNO}_3 + d\text{HI} $
