Awater molecule has polar o−h bonds that result in regions of partial positive charge (hydrogen atoms) and a region of partial negative charge (oxygen atom with lone pairs). place the na+ and cl− ions where h2o molecules are properly oriented to form ion–dipole interactions.

Na⁺ by the O and Cl⁻ by the H

Explanation:

See attachment for the drawing. The Na⁺ will form an ion-dipole interaction with the partially negative O since opposite charges attract. Similarly, the Cl⁻ will form an ion-dipole interaction with the partially positive H.

how to make a simple air condition

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
