Answer:
As a hen ages, the eggs that she lays get gradually larger. However, the calcium content deposited in the shell remains the same despite the size of the egg. So the eggshells become thinner as the hen ages.

Answer:
30.36moles
Explanation:
6CO2 + 6H2O → C6H12O6 + 6O2
From the equation above,
6moles of H2O are required to produce 1 mole of C6H12O6
Therefore, Xmol of H2O will be require to 5.06moles of C6H12O6 i.e
Xmol of H2O = 6 x 5.06 = 30.36moles
Therefore, 30.36moles of H2O are needed.
Answer:
d
Explanation:
Isomers are molecules that have the same molecular formula(the same number of each atom), but different structural formulas
in this case both have the formula C2H5O
I think it would be
Carbon + 2 Hydrogen= Carbon + Hydrogen + Carbon + 3 Hydrogen + 2 Bromine
But I’m not really sure, sorry if I’m wrong
Hope this helped
Answer:-
If an element has 3 or more valence electrons then the element belongs to p block of the periodic table. For p block elements the group number is found out by adding the number of electrons in valence shell + 10.
The reason for this is because in the middle of the periodic table there are the d block elements ranging from group 3 to group 12 a total of 10 groups in between elements having 2 valence electrons and 3 valence electrons
