The picture of correct answer is attached it is the second one from the left since it has 5 electrons in outermost shell so it can share 3 electrons to complete the octet rule, while first one contains only one electron in outermost shell so it easier to be lost, third one has 8 electrons so it has complete valence shell and last one with only two electrons in outermost shell so it is easier to lose these two electrons.
from 5 to 7 electrons on outermost shell can form covalent bond
Answer:
6.460 gm is the correct answer .
Explanation:
Given
Kate’s blood volume=
blood glucose=
As we know that
The 
includes the blood glucose of the 
So 
of the Kate’s blood volume can be determined by
To convert into the gm we have divided by the 1000
Therefore the glucose in her blood=
Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron = 
= initial temperature of water = 
Now put all the given values in the above formula, we get:
Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
