The oxidation number of hydrogen in HNC is +1.
In fact, the oxidation number of hydrogen in any compound will generally be +1; a major exception would be in the case of metal hydrides (e.g., NaH), where the hydrogen exists as a negative ion.
The true statement is that the metal on the right oxidizes more easily than the one on the left.
<h3>What is metal oxidization?</h3>
Metal oxidation is known to often occur if an ionic chemical reaction is said to take place on a metal's surface at the presence of oxygen.
Note that Electrons often move from the metal to the oxygen molecules in course of this process and as such The true statement is that the metal on the right oxidizes more easily than the one on the left.

Explanation:
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid. The cloudy white solution observed when CO2 is bubbled into limewater results from a reaction between Ca(OH)2 and either CO2 or H2CO3 to form an insoluble calcium carbonate precipitate.
Answer:
Given equation of parabola is
and
2
=64x ......(i)
The point at which the tangent to the curve is parallel to the line is the nearest point on the curve.
On differentiating both sides of equation (i), we get
2 y
