Answer : The moles of given compound is, 0.064 mole
Explanation : Given,
Mass of given compound = 40 g
Atomic mass of X = 50 amu
Atomic mass of Y = 45 amu
Atomic mass of Z = 10 amu
First we have to calculate the molar mass of given compound.
The given compound formula is, 
Molar mass of = (5 × Atomic mass of X) + (7 × Atomic mass of Y) + (6 × Atomic mass of Z)
Molar mass of = (5 × 50) + (7 × 45) + (6 × 10) = 625 g/mol
Now we have to calculate the moles of given compound.
Thus, the moles of given compound is, 0.064 mole
Answer:
21 gam
Explanation:
mH2SO4 = mddH2SO4.C% = 150. 14% = 21g
Answer: Polar air mass is the large mass of air formed over land or water in higher latitudes. They are characterized by cold air.
Tropical air mass is the large mass of air that is formed 25 degrees latitude of the equator. They are characterized by warm air.
Explanation:
Polar air mass is known for cold air near earth's surface. Polar air mass takes place in cold regions like Arctic region.
Unlike tropical air mass, polar air mass brings cold and dry air weather in winter season.
Continental polar mass takes place in cold, stable and low humid areas like subpolar land. Whereas, maritime polar air mass forms over oceans which are cool and located in polar region.
Tropical air mass is characterized by warm to hot air. But, as this air mass move away from their latitude of origin, they get cooled down. This phenomenon mostly result in precipitation and storms in Unites States. This also shows that tropical air mass contains moisture. They are usually prone to sudden changes.
Continental tropical air mass is produced over desert areas of the world during summer, when its hot. While, maritime tropical air mass is produced over tropical and subtropical oceans and seas in the world.
Explanation: Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated (having transverse streaks) and each acts independently of neighboring muscle fibers.
Answer:
True
Explanation:
This is because, The hydroboration oxidation of an alkene which is isobutene in the presence of a catalyst will result to alcohol as the product . Therefore, the OH group will attach or link itself to the carbon which is less obstructed. Thus this reaction is in accordance to Anti-Markownikoff's rule.
So isobutene on hydroboration oxidation will produce ter isobutyl alcohol.
