Answer:

The correct option (c) "is held together by ionic bonds".

Step-by-step explanation:

Table salt is NaCl. It is a combination of Sodium and Chlorine.

There is 1 valance electron in sodium. Its electronic configuration is 2,8,1

The electronic configuration of Chlorine is 2,8,7. It means that it needs 1 electron so that its octet gets completed.

Na transfers one electron to Cl. It becomes Na⁺. Cl gains one electron From Na. It becomes Cl⁻.

As a resuslt, Na⁺ and Cl⁻ forms. Both Na and Cl are ions. They held together by ionic bonds.

The mean length of the sides of a triangular plot of land is 18 yards.

Sunny_sXe [5.5K]

The mean is all of them added together divided by the number, so multiple the mean by the number of sides, 3, and that's the perimeter. 18 x 3 = 54

What is an equation of the line that passes through the points (-4,1) and (4,4)?

Ray Of Light [21]

Answer:

y = $\frac{3}{8} x + \frac{5}{2}$

Step-by-step explanation:

☆Remember: $m = \frac{y_2 - y_1}{x_2 - x_1}$

☆Remember: Slope-intercept form -> y = mx + b

☆Now. We first need to find the slope.

$m = \frac{4 - 1}{4 - (- 4)} = \frac{3}{8}$

☆Now the y-intercept.

$y = mx + b \\ \\ 4 = \frac{3}{8} (4) + b \\ \\ 4 = \frac{3}{2} + b \\ \frac{ - \frac{ 3}{ 2} = - \frac{ 3}{ 2} \: \: \: \: \: \: \: \: \: \: }{ \frac{5}{2} = b }$
