Answer:
d.
Explanation:
It is a force that occurs when surfaces touch each other.
The volume of NH₃ produced at STP : 0.237 L
<h3>Further explanation</h3>
Reaction
N₂ + 3H₂ → 2NH₃
1 mol = 6.02 x 10²³ particles
9.6 X 10²¹ molecules of Hydrogen, mol :
mol H₂ : mol NH₃ = 3 : 2
mol NH₃ :
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). <em>At STP, Vm is 22.4 liters/mol.</em>
The volume of NH₃ :

Local winds blow over certain parts of the Earth, but global winds blow around the globe as the name 'global' suggests.
Local winds like the Sirocco, Harmattan, leveche, Nor'westers, Mistral, Chinook, Foehn can be found only in certain regions. For example, Sirocco, Harmattan, are seasonal winds blowing across Northern Africa and the Leveche blows over Southern Spain. The Chinook are warm winds flowing down the leeward side of the Rocky Mountains. The Mistral is a chilly wind which blow in the Mediterranean regions during winter.
The Trade winds, Mid Latitude Westerlies and Polar Easterlies are examples of global winds.
The Trade Winds are found between the 30 degrees S and N latitudes. There are the North-East Trades and the South-East Trades, both converging at the the Equator.
The Westerlies are a deep wind system found in the Temperate latitudes blowing from the West towards the East.
The Polar Easterlies blow from the Polar regions towards the Mid-latitudes.

Yes a precipitate of Calcium Carbonate is formed since it is insoluble in water.
Mol Wt of Calcium Nitrate is 164. And that of Calcium Carbonate is 100.
One mole of Calcium Nitrate produces one mole of Calcium Carbonate.
i.e. 164 gms will produce 100gms of precipitate
So, 1.74gms of Calcium Carbonate will be obtained from 2.85gms Calcium Nitrate present in the original solution.</span>
