The ionic compounds naclnacl and mgsmgs are represented by the diagrams above. which statement correctly identifies diagram 1 and identifies the compound with the lower melting point, explaining why?

check explanation

Explanation:

No diagram is given above but to determine the value of melting point we need to understand the fact that NaCl has a lower melting point than MgS.

Reasons are; (1) sodium ion (+1) in the first group of the periodic table is characterized by its softness and low melting point and, (2). Is that it has a lower melting point than MgS because the COULUMBIC ATTRACTIONS between its singly charged sodium ions(+1) and the chlorine ions(-1) are weaker than those between the ions in MgS.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
