sun rays will not penetrate the ozone layer. they enters the earths atmosphere by the radiation processes. Ozone Layer gets depleted by the action of chlorofluorocarbons which were released by automobiles and refrigerators. and that results in the entry of UV rays which are harmful for life forms. and global warming phenomena is a result of greenhouse effect which explains the phenomenon of the heat which entered Earth's atmosphere by radiation, does not completely reflected back! rather, it (heat) gets stored in the atmosphere which results in the increase in temperature of the earth! and global warming was useful upto some extent in our ancient days. It resulted in the melting of himalayan ice mountains which in turn resulted in the increase of sea level. but now, global warming has become a major headache for us!
I believe that present day was a theory that became a evolution developed because it was a historical event involved
Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
= 
X= 
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
