Write the IUPAC name for the binary ionic compound Na2O? How would it be used?

IUPAC name of Na2O is sodium oxide.

Na2O is the ionic compound containing sodium and oxygen in molar ratio of 2:1. This compound is named by International Union for Pure and Applied Chemistry as Sodium oxide.

This substance is used in a varied number of cases. Its the anhydride of the popularly used base sodium hydroxide. So adding waste produces sodium hydroxide solution. Its used in glass and ceramic factories too. Sodium silicates are also produced from this substance. Its also used to produce soda ash.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
