a) They are solid at ambient temperatures of 25 ° C and pressure of 1 atm.
b) Ionic compounds represent high temperature melting and boiling.
c) They are hard and brittle and then subjected to the impact, break easily, creating planar faces.
d) When dissolved in water, or pure liquid, carry electrical current due to the existence of ions that move freely and can be attracted by the electrodes, closing the electric circuit.

Answer: sunlight, water, air, habitat, and food.
Explanation: we are all living organisms and we all have our five basic necessities for survival; sunlight, water, air, habitat, and food.
A conductor transmits heat and electrical good.
The moles of each element found in a 5.00 g nickel coin is calculated as below
moles =mass/molar mass
calculate the mass of each element =% composition of element/100 x total mass of nickel
Mn = 9/100 x5 = 0.45g
Cu=56/100 x5= 2.8 g
Ag= 35/100x5= 1.75 g
moles of each element is therefore=
Mn = 0.45g/54.94 = 8.19 x10^-3 moles
Ag=1.75g/107.87 g/mol = 0.0162 moles
Cu = 2.8 g/63.5 g/mol=0.0441 moles
