Point (20, 5) is on the graph of inverse variation. Which of the following ordered pair is on the graph?.

Bess [88]

The point $(10, 10)$ is on the graph.

<h3>Procedure - Inverse variation</h3><h3 /><h3>Inverse variation model</h3><h3 />

An <em>inverse</em> variation is represented by the following formula:

$y = \frac{k}{x}$ (1)

Where:

$x$ - Independent variable.
$y$ - Dependent variable.
$k$ - Proportionality constant.

We can eliminate the proportionality constant by creating the following relationship:

$x_{1}\cdot y_{1} = x_{2}\cdot y_{2}$ (2)

<h3>Determination of another point</h3>

If we know that $x_{1} = 20$ , $y_{1} = 5$ and $x_{2} = 10$ , then the remaining variable is:

$y_{2} = \left(\frac{x_{1}}{x_{2}} \right)\cdot y_{1}$

$y_{2} = \left(\frac{20}{10} \right)\cdot (5)$

$y_{2} = 10$

The point $(10, 10)$ is on the graph. (Correct choice: C) $\blacksquare$

List the following compounds in decreasing electronegativity difference.

nikdorinn [45]

Answer:

Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1

Explanation:

Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0

Electronegativity difference in NaCl = 3.2-0.9 = 2.3

Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1

Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2

Based on the sign of the standard cell potential, ????∘cell, classify these reactions as spontaneous or nonspontaneous as writte

Ratling [72]

For a cell reaction to be sponteanous, the standard cell potential must be positive.

<h3>What is a sponteanous cell reaction?</h3>

We define a cell reaction as sponteanous when the value of the standard cell potential is positive. If the standard cell potential is negative then the reaction is not sponteanous.

The question here is incompete but we know that the reactions that are sponteanous will all have a positive standard cell potential.
