C
Explanation:
energy cannot be created or destroyed like solar energy for instance. it is already energy because it comes from the sun and for other reason.
Hope this helps!
Answer:
1.2
Explanation:
Molarity = moles/volume
to find the moles, you must multiply both sides by volume
so, take 1.5 L * 0.80 M
this equals 1.2 :)
Answer:
According to Le-chatelier principle, equilibrium will shift towards left to minimize concentration of and keep same equilibrium constant
Explanation:
In this buffer following equilibrium exists -
So, is involved in the above equilibrium.
When a strong base is added to this buffer, then concentration of increases. Hence, according to Le-chatelier principle, above equilibrium will shift towards left to minimize concentration of and keep same equilibrium constant.
Therefore excess amount of combines with to produce ammonia and water. So, effect of addition of strong base on pH of buffer gets minimized.
I have heard they can use hair is stocking or nets to absorb the oil out of the water
Answer:
I think it is called demagnetisation.
