Answer 1: Option(B) Nitrogen

Explanation:

The earth's atmosphere comprises of different gases which are Nitrogen(78%), plenty of Oxygen(21%), argon(0.9%) and remaining are the methane, gaseous oxides etc. So Nitrogen is present in largest quantity in the earth's atmosphere.

Answer 2: Option(D) Ozone

Explanation:

The Stratosphere is the second lowest layer of the earth. It contains the ozone which absorbs the UV rays coming form the sun because of which there is a rise in temperature than other layers.

Answer 3: Option(A) Heat from the earths core

Explanation:

The heat energy coming from the Sun heats the earth non-uniformly that results in the hot and cold area on the earth causes low and high air pressure.The Sun heats the earth core. When there is a hot weather the land near the sea becomes hot in comparison with the sea results in the hot wind flow from the sea.

Entropy can be thought of as the degree of disorganization of a system.<br> TRUE<br> FALSE
Mice21 [21]

Answer:

True

Explanation:

The entropy of a system denoted by S is a thermodynamic function that increases in value when there are more ways to arrange the particles in the system. Some spontaneous chemical processes are entropy driven. An increase in entropy is said to drive the dissolution of ionic salts along with the evaporation of water are related to the spreading out of energy.

The entropy of a system can be taken as a measure of disorder of a system. In a spontaneous chemical process, the entropy of the universe is said to increase. ΔSunivu>0. Making the answer true.

Ammonium chloride is used as an expectorant in cough medicine. It has a density of 1.53 g/cm^3. What is the mass of 26.0L of thi
Katena32 [7]

Answer:

                     39.78 Kg

Explanation:

Data Given;

                  Density  =  1.53 g/cm³

                  Mass  =  <u>??</u>

                  Volume  =  26.0 L  =  26000 cm³

Formula Used;

                       The measure of mass per unit volume is called as density. It is a physical property of a substance and tells how tightly the particles are packed. Mathematically;

                  Density  =  Mass ÷ Volume

Solving for Mass,

                  Mass  =  Volume × Density

Putting values,

                  Mass  =  26000 cm³ × 1.53 g.mL⁻¹

                  Mass  =  39780 g  or   39.78 Kg
