Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.

Answer:

The atmosphere of the earth refers to the gaseous envelope where various types of gases are present at a definite proportion. The major dominant gas is Nitrogen which is nearly 78%, next to this is the oxygen gas which is about 21% and Argon is present at about 1%. Some of the gases that are present in trace amount includes hydrogen. helium, carbon dioxide, ozone, methane, water vapor and many more. This composition of the atmosphere maintains the overall temperature of the earth by interacting with the incoming solar radiation.

There are certain solids that are very small and tiny particles found to be floating within the atmosphere. These are aerosol particles, dust particles, pollen and spores which are mainly emitted from the volcanic eruptions and sea spray. The aerosols are very fine suspended solid particles present abundantly in the atmosphere. They are originated both naturally and due to human activities. These fine particles help in maintaining a cooler temperature by decreasing the quantity of solar radiation emitted from the sun. These are so small that it can be lifted up easily into the higher atmosphere due to the wind factor.

What volume of 0.160 m li2s solution is required to completely react with 130 ml of 0.160 m co no3 2?
Over [174]
The  volume  of  0.160    m   Li2S  solution  required  to  completely  react  with  130 ml  of 0.160  CO(NO3)2  is calculated   as  below

write the  reacting  equation

Co(NO3)2 +  Li2S = 2LiNO3  +  COS

find the    moles  of CO(NO3)2  = molarity  x  volume

=  130 ml  x  0.160=20.8  moles

since the reacting moles between CO(NO3)2  to LiS  is   1:1  the  moles of LiS  is  also  20.8  moles

volume  of Lis  is  therefore =  moles of Lis/ molarity  of LiS

=  20.8/0.160 =  130 Ml

Which term best describes this reaction? 2 carbons double bonded to each other, with CH 3 above the left C and H above the right
Ierofanga [76]

Answer:

addition polymerization

Explanation:

In addition polymerization, the monomers are simply joined to each other to form a polymer having the same empirical formula as the monomer but of higher relative molecular mass. The monomers in addition polymerization are usually simple unsaturated molecules such as alkenes.

We can deduce the reaction to be an addition polymerization because of the the attachment of n to both the unsaturated monomer and the saturated polymer without the loss of any small molecule. If it was a condensation polymerization, there would have been an accompanying loss of a small molecule such as water.
