The oxidation state of phosphorus in hypophosphoric acid is + _____
Correct answer is 4
The molecular structure of hypophosphoric acid (\(\text{H}_4\text{P}_2\text{O}_6\)) is given by:
This structure shows two phosphorus atoms bonded to oxygen atoms and hydroxyl groups. The oxidation state of phosphorus (P) in hypophosphoric acid is +4, which is determined by considering the bonding of phosphorus with oxygen and hydrogen atoms in the molecule.
The oxidation state is essential for understanding the reactivity and the acidic nature of the compound.
In the given circuit the sliding contact is pulled outwards such that the electric current in the circuit changes at the rate of 8 A/s. At an instant when R is 12 Ω, the value of the current in the circuit will be A.
Let A be a 3 × 3 matrix such that \(\text{det}(A) = 5\). If \(\text{det}(3 \, \text{adj}(2A)) = 2^{\alpha \cdot 3^{\beta} \cdot 5^{\gamma}}\), then \( (\alpha + \beta + \gamma) \) is equal to:
