The identity of the unknown compound is Urea from the Table# given. The reason for this identification will further be discussed below.

<h3>What is melting point?</h3>

Melting point can be defined as the point at which a substance changes from a solid phase or state to a liquid state

When two substances of different melting points are added together, the total melting point obtained is usually depressed.

From the table,

  • When urea and benzoic acid is added the melting point range becomes = 117-120

  • When urea and Cinnamic acid is added the melting point range becomes= 100-125, and both of which is lower than the individual melting points.

Therefore, the identity of the unknown compound is Urea from the Table# given.

Answer:

5×10⁵ L of ammonia (NH3)

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

N2 + 3H2 —> 2NH3

From the balanced equation above, we can say that:

3 L of H2 reacted to produce 2 L of NH3.

Finally, we shall determine the volume of ammonia (NH3) produced by the reaction of 7.5×10⁵ L of H2. This can be obtained as illustrated below:

From the balanced equation above,

3 L of H2 reacted to produce 2 L of NH3.

Therefore, 7.5×10⁵ L of H2 will react to produce = (7.5×10⁵ × 2)/3 = 5×10⁵ L of NH3.

Thus, 5×10⁵ L of ammonia (NH3) is produced from the reaction.

Why is it impossible to have an undiscovered element that would fit between sodium and magnesuim
Stolb23 [73]

Answer:

Sodium has 11 protons and Magnesium has 12. The way that the periodic table is set up doesn't allow for any elements to be in between. The element would have to have 11.5 protons, which is impossible
