Which of the following is known as ammonia? |
NH3 PH3 NO3 NO2 |
NH3 |
The correct answer is option 1. \(NH_3\). \(NH_3\) is the chemical formula for ammonia, a colorless gas with a pungent odor. It is widely used in various applications like fertilizers, refrigerants, and as a cleaning agent. \(PH_3\) is the formula for phosphine, a colorless gas with a garlic-like odor. It is a highly toxic compound. \(NO_3\) is the formula for the nitrate ion, a polyatomic ion commonly found in salts like potassium nitrate \((KNO_3)\) and sodium nitrate \((NaNO_3)\). \(NO_2\) is the formula for nitrogen dioxide, a reddish-brown gas with a pungent odor. It is a major air pollutant. Therefore, based on the chemical formulas, NH3 is the only option corresponding to ammonia. |
