Answer:
If the electronegativity difference is greater than 2.0, then the bond is ionic.
Explanation:
For ex:
Na has the electronegativity of 0.93
Cl has the electronegativity of 3.16
we subtract 3.16-0.93
We have 2.23 electronegativity difference between Na and Cl
because 2.23 > 2.0
therefore NaCl compound has an ionic bond.
Answer:
K is the symbol for potassium
Answer:
C. Balanced forces caused a change in the motion of the plates.
Explanation:
Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.
Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
Explanation:
According to the standard conversion,
Therefore, 675,000 Joules will be converted into kcal as follows.
Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
