Answer:
Option D. T
Explanation:
Enthalpy change (ΔH) is simply the difference between the heat content of the product (Hp) and the heat content of the reactant (Hr). Mathematically, it is expressed as:
Enthalpy change (ΔH) = Heat of product (Hp) – heat of reactant (Hr)
ΔH = Hp – Hr
From the diagram given above, the difference between the heat content of product and the heat content of reactant is T.
Therefore, the enthalpy change of the reaction is T.
They have luster, good thermal and electrical conductivity, high densities and melting points, and are malleable. The only exception would be mercury most metals are solid at room temp
Answer:
Explanation:
A change in oxidation number represents a transfer of electrons between atoms/ions. This is what happens during oxidation and reductions, where electrons are gained and lost (respectively).
The elements in each group have<span> the </span>same<span> number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (</span>group<span> one) </span>has<span> one electron in its outer shell.</span>
The liver cells produce proteins to avoid blood clotting. They also break down old or damaged blood cells.
