The artificial sweetener used only for cold food is Saccharin

In the context of controlling humidity, we explore which chemical among the given options is most effective for this purpose.

1. Charcoal: Primarily used for filtration and absorption of impurities, it is not typically used for controlling humidity.

2. Silica gel: A desiccant, designed specifically to absorb moisture from the air, making it highly effective in humidity control.

3. Ammonia gas: More commonly used in industrial refrigeration and cleaning products, rather than for humidity control.

4. Sodium chloride: Known as table salt, it is not used for humidity control; it is more often associated with de-icing and seasonings.

Upon analysis, Silica gel is confirmed as the correct choice due to its ability to effectively manage humidity by absorbing moisture.

Correct Answer: Silica gel

In order to determine which compound is not an analgesic, we first need to understand what constitutes an analgesic and compare it with the given options.

1. Analgesics: Analgesics are substances that relieve pain without causing the loss of consciousness. They are often used to manage discomfort caused by various conditions.

2. Given Options:

• Morphine: A potent opiate often used for severe pain relief. It is widely recognized as an analgesic.
• Heroin: Also known as diacetylmorphine, it is derived from morphine and has strong analgesic properties, although it is illegal in many places due to its high potential for addiction and abuse.
• Codeine: Another opiate, it is used for mild to moderate pain relief and acts as an analgesic.
• Ranitidine: This is an H2 histamine blocker used to reduce stomach acid and treat conditions such as ulcers and gastroesophageal reflux disease (GERD). It does not function as an analgesic.

Conclusion: Analyzing the provided options, Ranitidine is the compound that does not exhibit analgesic properties.

Thus, the correct answer is Ranitidine.

1. Chloroform is a compound with the formula CHCl₃. When exposed to light, particularly UV light, it is susceptible to reaction due to the presence of its carbon-halogen bonds.
2. Oxygen in the air acts as an oxidizing agent. When chloroform is exposed to oxygen under light conditions, the energy from the light acts as a catalyst for the reaction.
3. The reaction can be simplified into the equation:
   CHCl₃ + O₂ → COCl₂ + 2HCl
4. In this equation, chloroform reacts with oxygen to form phosgene (COCl₂) and hydrogen chloride (HCl) gas.
