The chemical element of atomic number 7, a colorless, odorless unreactive gas that forms
about 78 percent of the earth's atmosphere.
Solution:
Since we have ml=-1
it shows that it has two 2e- i;e it fond in 2nd subshell in f orbital. And each subshell can hold 2 e-.
Thus the required answer is 2 electrons hold by an atom.
Answer:
We say that the solution is unsaturated.
Explanation:
If the salt solubility is 36 g in 0.1 L of water then we can dissolve 360 g of salt in 1 L of water.
Because the solution contains 200 g of salt in 1 L of water, the solution is unsaturated because more salt can be added until we reach the saturation point.
We call the solution dilute when we compare the concentration of a solution with the concentration of another solution, but here we do not compare different solutions.
Grinding pepper. It is still pepper.
I hope this helps!
C. Convection currents in the air
Explanation:
Near the shore, winds tends to blow out towards the water at night and this is driven by convection currents in the air.
Convection occurs in fluids. Since we are dealing with wind, therefore, it is convection in air.
- At night, the air on land is cold and under high pressure.
- The shore area is able lose and gain heat very fast.
- At night, since the shore is cold, the air around is cold too.
- The ocean has high heat capacity and does not lose or gain heat easily.
- At night, it still retains come of its heat.
- This causes nearby winds to warm up, becomes less dense and rises.
- The wind here is moves towards the cold land
- The breeze on land moves outwards towards the ocean.
- This will then set up convection currents.
