The compound of Phosphorus with Hydrogen is a gas that has the same density as hydrogen sulfide H2S. Determine the chemical formula of this compound.
Accepted Answer
The compound of phosphorus and hydrogen is phosphine (PH3). Here's why:
Density Comparison: The statement mentions the compound has the same density as hydrogen sulfide (H2S). While density is a useful property, it's not directly related to determining the formula of a compound.
Phosphorus and Hydrogen: Phosphorus (P) and hydrogen (H) are known to form a compound called phosphine (PH3). Phosphine is a colorless, flammable gas with a characteristic garlic-like odor.
Determining the Formula: The formula PH3 is determined by considering the valencies of phosphorus and hydrogen. Phosphorus typically forms three bonds, and hydrogen forms one bond. This leads to the formula PH3.
