The choices are not given, however, the question can still be solved.

<u>We know that:</u>
pH + pOH = 14
<u>Converting the above equation to concentration form, we will get:</u>
[H₃O+] * [OH-] = 10⁻¹⁴

<u>We are given that:</u>
concentration of hydroxide ion [OH-] = 1.4 * 10⁻¹⁰ M

<u>Substitute with this in the above equation to get concentration of hydronium ion as follows:</u>
[H₃O+] * [OH-] = 10⁻¹⁴
[H₃O+] * [1.4 * 10⁻¹⁰ ] = 10⁻¹⁴
[H₃O+] = \frac{10^{-14} }{1.4* 10^{-10} }
[H₃O+] = 7.1428 * 10⁻⁵ M

Hope this helps :)

What is the slope of the line that passes through points (2,-3) and (5,1)
Ivenika [448]

Find the difference in the y-coordinates: -3 - 1 = -4

Find the difference in the x-coordinates in the same order: 2 - 5 = -3

Divide the difference in y by the difference in x: slope = (-4)/(-3)

Reduce the fraction: slope = 4/3

Kim is watching a satellite launch from an observation spot 6 miles away. Find the angle of elevation from Kim to the satellite,
Allisa [31]

Answer:

Angle of elevation from Kim to the satellite launch = 6.654°

Step-by-step explanation:

The distance from Kim to the satellite launch

= 6 miles

Height of the satellite launch

= 0.7 miles

Angle of elevation from Kim to the satellite launch = b

Tan b = height of satellite/distance from Kim

Tan b= 0.7/6

Tan b= 0.1166667

b = tan^-1 (0.1166667)

b= 6.654°

Angle of elevation from Kim to the satellite launch = 6.654°
