Answer:
since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
Explanation:
Answer:-
2747.7 Cal mol -1
Explanation:-
Molar heat of Fusion is defined as the amount of heat necessary to melt (or freeze) 1 mole of a substance at its melting point.
Atomic mass of Iron = 55.845 g mol-1
Mass of Iron = 200 g
Number of moles of Iron = 200 g / (55.845 g mol-)
= 3.581 moles
Heat released = 9840 Cal
Molar heat of Fusion = Heat released / Number of moles
= 9840 Cal / 3.581 moles
= 2747.7 Cal mol -1
Answer:
Polar
Step-by-step explanation:
Electronegativity increases from <em>left to right</em> in the Periodic Table.
Cl is further right than C (both tinted pink) in the portion of the Periodic Table below.
Cl is <em>more electronegative</em> than C, so the Cl has a partial negative charge and the C has a partial positive charge.
The C-Cl bond is polar.
