In 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.
<h3>What is James Webb Telescope?</h3>
The James Webb Telescope is the most important optical telescope present in space, which is employed by astronomers to observe celestial bodies and physical phenomena in the universe.
This space telescope (James Webb Telescope) is based on the infrared wavelengths that cover a specific length of 0.57 to 28-micrometer waves and enable to observe different spectra across the Universe.
In conclusion, in 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.

Answer:
206 kj of heat is required to boil 78.5 kg of water at its boiling point
<u>Answer:</u> The solubility of carbon dioxide at 5.50 atm is ![0.886g/100mL](https://tex.z-dn.net/?f=0.886g%2F100mL)
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
![C_{A}=K_H\times p_{A}](https://tex.z-dn.net/?f=C_%7BA%7D%3DK_H%5Ctimes%20p_%7BA%7D)
Or,
![\frac{C_{1}}{C_{2}}=\frac{p_{1}}{p_2}](https://tex.z-dn.net/?f=%5Cfrac%7BC_%7B1%7D%7D%7BC_%7B2%7D%7D%3D%5Cfrac%7Bp_%7B1%7D%7D%7Bp_2%7D)
where,
are the initial concentration and partial pressure of carbon dioxide
are the final concentration and partial pressure of carbon dioxide
We are given:
![C_1=0.161g/100mL\\p_1=1.00atm\\C_2=?\\p_2=5.50atm](https://tex.z-dn.net/?f=C_1%3D0.161g%2F100mL%5C%5Cp_1%3D1.00atm%5C%5CC_2%3D%3F%5C%5Cp_2%3D5.50atm)
Putting values in above equation, we get:
![\frac{0.161g/100mL}{C_2}=\frac{1.00atm}{5.50atm}\\\\C_2=\frac{0.161g/100mL\times 5.50atm}{1.00atm}=0.886g/100mL](https://tex.z-dn.net/?f=%5Cfrac%7B0.161g%2F100mL%7D%7BC_2%7D%3D%5Cfrac%7B1.00atm%7D%7B5.50atm%7D%5C%5C%5C%5CC_2%3D%5Cfrac%7B0.161g%2F100mL%5Ctimes%205.50atm%7D%7B1.00atm%7D%3D0.886g%2F100mL)
Hence, the solubility of carbon dioxide at 5.50 atm is ![0.886g/100mL](https://tex.z-dn.net/?f=0.886g%2F100mL)
Answer:
8.45 moles are produced
Explanation:
CaCl₂ + Na₂CO₃ → CaCO₃ + 2 NaCl
From the equation, we can see that for every 1 mole of CaCl₂ and 1 mole Na₂CO₃ will give 1 mole of CaCO₃ and 2 moles of NaCl
to calculate how many moles of CaCO₃ ,we simply multiply multiply each by the 8.45 moles of CaCl₂ which will reacts
these is because for every 1 mole of CaCl₂ and 1 mole Na₂CO₃ will give 1 mole of CaCO₃ and 2 moles of NaCl
therefore we have every 1x8.45(8.45) mole of CaCl₂ and 1x8.45(8.45) mole Na₂CO₃ will give 1x8.45(8.45) mole of CaCO₃ and 2x8.45(16.9) moles of NaCl
8.45 moles are produced in the reaction
