As we go down the group the number of energy level increases
and the nuclear attraction decreases
therefore ability to remove electron increases
therefore first ionization energy decrease(as it can be removed easily the energy needed is less)
Therefore answer c
Explanation:
As per Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.
Since, the given reaction is exothermic in nature so, when we increase the temperature then reaction will shift in the direction opposing the increase in temperature. Hence, the equilibrium will shift on left side when we increase the temperature.
On the other hand, when we decrease the temperature then the equilibrium will shift on the right side.
The conglomeration of two quantities.
Two quantities that go together to become a new identity.
Here are two different definitions you can put in! Hope this helps! Please give brainliest❤️
Explanation:
The given balanced reaction equation is as follows.
The given data is as follows.
Mass of solution (that is sample) = 0.5 g
Therefore, calculate the mass of solute as follows.
= 0.178704 g Fe
Now, calculate the percent by mass Fe in the ore as follows.
Percent by mass of Fe in the ore =
=
= 35.7%
Thus, we can conclude that percent by mass of iron in the ore is 35.7%.
