The portion of the electromagnetic spectrum do we need to observe is the red part of the This is further explained below.
<h3>What is
electromagnetic spectrum?</h3>
Generally, Spectrum refers to the range of wavelengths or frequencies that electromagnetic radiation may cover.
In conclusion, We need to keep an eye on the red part of the electromagnetic spectrum since a large positive redshift causes an increase in wavelength and a corresponding fall in frequency and photon energy (such as light).

The molecular mass of a 2.66g sample of gas at a temperature of pressure of 845torr and occupying a volume of 0.70L is 84.16g/mol.
<h3>How to calculate molecular mass?</h3>
The molecular mass can be calculated by first calculating the number of moles using the following formula:
PV = nRT
Where;
- P = pressure
- V = volume
- n = no of moles
- R = gas law constant
- T = temperature
1.112 × 0.7 = n × 0.0821 × 300
0.7784 = 24.63n
n = 0.032mol
molecular mass = 2.66g ÷ 0.032mol
molecular mass = 84.16g/mol
Therefore, the molecular mass of a 2.66g sample of gas at a temperature of pressure of 845torr and occupying a volume of 0.70L is 84.16g/mol.

1) Troposphere is the nearest layer to the earth.
2) Range from 5 to 11 miles in thickness.
3) Contains almost all of the atmospheric water vapor.
1. The Precambrian is the earliest part of Earth's history, set before the current Phanerozoic Eon.
2.The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period.
3. During the Precambrian era the earth started cooling and the outer edge of the planet solidified from molten lava to a solid crust. Water rained from the atmosphere and created oceans.
4. It is The first and longest subdivision of time for the earth.
5. The earth took form about 4.5 billion years ago. For the first 4 billion years of that time, the Earth was growing and changing.
6. he only multi-cellular life forms at the end of the Precambrian were in the oceans and included some groups that have survived until the present: jellyfishes and segmented worms.
7. The discovery of 3.85-billion-year-old marine sediments and pillow lavas in Greenland indicates the existence of liquid water and implies a surface temperature above 0 °C (32 °F) during the early part of Precambrian time.
8. The Precambrian encompasses the Archean and Proterozoic eons, which are formal geologic intervals that lasted from 4 billion to about 541 million years ago.
9. Precambrian rocks on most continents have revealed that additional primitive life-forms existed approximately 3.5 billion years ago.
10. The earliest evidence for the advent of life includes Precambrian microfossils that resemble algae, cysts of flagellates, tubes interpreted to be the remains of filamentous organisms, and stromatolites (sheetlike mats precipitated by communities of microorganisms).
Cleaning the nose piercing with a few simple steps will help prevent pre-existing conditions like infections, allergic reactions or skin damage. Performing regular maintenance will keep your piercing cleaner, more comfortable and easier to clean in the future.(Remember: If you have any problems I recommend visiting a doctor at your earliest convenience!) Antibacterial soap is great at reducing inflammation and clearing up infections. You should soak your nose in it regularly and use a clean cloth to gently wash away any particles that may have fallen into the septum.
