The solid block shown below has a mass of 146 grams. THE DIMENSIONS OF THE BLOCK ARE- 3.0 cm by 4.5 cm by 7.0 cm. What is the block’s density? D=m/v

Explanation:

D=m÷v

D=146÷(3×4.5×7)

D=146÷94.5

D=1.54g/cm^3

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
