a) These telescopes must make observations above much of the water vapor in the atmosphere because water can block infrared rays.

Explanation:

Ground- based infrared telescopes are placed in a high altitudes dry climates because the telescopes must make observations above much of water vapor since they cut and block them off.

  • Telescopes are devices that are used to observe very distant objects.
  • An infrared telescope is sensitive to infrared rays.
  • Infrared rays are part of the electromagnetic radiations.
  • These rays are usually blocked off by the presence of water vapor.
  • Desert areas that lacks water vapor in the atmosphere are the most desired for sighting such facilities.

The pH of a solution is 3.81. What is the OH concentration in the solution?​
disa [49]

Answer:

6.46 × 10⁻¹¹ M

Explanation:

Step 1: Given data

pH of the solution: 3.81

Step 2: Calculate the pOH of the solution

We will use the following expression.

pH + pOH = 14.00

pOH = 14.00 - pH = 14.00 - 3.81 = 10.19

Step 3: Calculate the concentration of OH⁻ ions

We will use the definition of pOH.

pOH = -log [OH⁻]

[OH⁻] = antilog -pOH = antilog -10.19 = 6.46 × 10⁻¹¹ M
