<h2>Answer with Explanation </h2>
The equations must be used to calculate the heat associated with phase change is,
Q=m×∆H(vap)
or Q=m×∆H(fus)
here;
∆H= heat required for one gram of the substance to undergo the phase change.
*If you're going from solid to liquid, you use ∆H-heat of fusion (called the heat of fusion), which represents the heat required for 1 gram of a substance to change from solid to liquid at the melting point.
*If you're going from liquid to gas, you use ∆H-heat of vaporization (called the heat of vaporization), which represents the heat required for 1 gram of the substance to change from liquid to gas at boiling point.
For water, the values are usually given to be
ΔHfus = 334 J/g and
ΔHvap=2257 J/g.
The Lewis structure of
Diimide (N₂H₂) is shown below.
In this molecule two Nitrogen atoms attached to each other through a
double bond are further attached to one one Hydrogen atom. Also, each Nitrogen atom carries one
non-binding electron pair (
Lone Pair) (Highlighted RED).
Result: Option-C (<span>each nitrogen has one nonbinding electron pair) is the correct answer.</span>
<em>6.13 x 10²⁴ atoms of Na = (6.13 * 10²⁴)/6.023 * 10²³ moles of Na = 10.17 moles</em>
The vultures would eventually decrease also because the vultures feed off the dead gazelles
Glacial erosion is the process by which a glacial flows over the land, picking up rocks.
