Explanation:
There are government khatris as well, which are maintained by the panchayat. Kuhls are a traditional irrigation system in Himachal Pradesh- surface channels diverting water from natural flowing streams (khuds). A typical community kuhl services six to 30 farmers, irrigating an area of about 20 ha.
The first shell can hold up to two electrons maximum.
From the periodic table, we can find that hydrogen has only one electron occupying the first shell. Therefore, hydrogen would require an additional one electron to fill up the first shell.
Answer:
Option A is correct. The system is at equilibrium
Explanation:
Step 1: Data given
Kc at 1300 K = 5.00
Initial concentration of SO2 = 1.20 M
Initial concentration of O2 = 0.45 M
The concentration of SO3 = 1.80 M
When Q=K, the system is at equilibrium and there is no shift to either the left or the right.
When Q<K, there are more reactants than products. As a result, some of the reactants will become products, causing the reaction to shift to the right.
When Q>K, there are more products than reactants. To decrease the amount of products, the reaction will shift to the left and produce more reactants.
Step 2: The balanced equation
2 SO2(g) + O2(g) ⇌ 2 SO3(g)
Step 3: Calculate Q
Q = [SO3]² / [O2][SO2]²
Q = 1.80²/0.45*1.20²
Q = 5.00
Q = Kc
This means , the system is at equilibrium and there is no shift to either the left or the right.
Option A is correct.
Answer:
The correct answer is due to the difference in pressure inside and outside the bottle.
Explanation:
Liquids have melting and boiling points that depend on pressure and temperature. The pressure inside the bottle is higher than the pressure outside. This causes the melting point to drop, making the liquid freeze at a lower temperature than if it were at atmospheric pressure, and therefore has a lower temperature than it would freeze at atmospheric pressure. When the bottle is uncovered, the liquid becomes an atmospheric pressure, and due to the temperature acquired when the bottle was closed the liquid freezes.
Have a nice day!
