Which compound listed below is most likely to have to following properties?
-solid at room temperature
- high melting points
-solble in water
-conductive when dissolved
1.sodium chloride
2.carbon monoxide
3.nitrogen trifluoride
4.none of these compounds could have all of the properties listed

1.sodium chloride

Explanation:

because the others dont have all the listed properties

it takes on an electronical energy

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.
