The products of chemical reactions often have completely different properties than the reactants, like viscosity, boiling and melting temperatures, etc.
That is because the atoms form new and different bonds to give the products.
Answer:
An autotroph absorbs sunlight from their stoma and converts this solar energy to chemical energy with their chloroplasts. As you can see, the sun's interaction of matter and energy is vital to sustaining all living things on Earth.
Explanation:
Answer:
Thus the order of covalent character will be
DG < EG < DF < DE
Explanation:
The electronegativity decides the nature of bond formed between two atoms.
More the difference in electronegativity more the ionic character in the bond formed.
Let us check the electronegativity difference between the elements forming molecules
a) DE :
3.8-3.3 = 0.5
b) DG :
3.8-1.3 = 2.5
c) EG
3.3-1.3 = 2
d) DF
3.8-2.8 = 1.3
So the maximum ionic character will be in DG and minimum in DE
Thus the order of covalent character will be
DG < EG < DF < DE
Atomic number = 20 -------> Ca (calcium)
Calcium has four shells (1, 2, 3, 4) and two sublevels ( s, p ).
1s² 2s² 2p⁶ 3s² 3p⁶ 4s²
Answer:
B
Explanation:
They are directly proportional. That's what the relationship states
