Answer:

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

If 22.99 g of sodium and 35.45 g of chlorine fully react, how much sodium chloride forms?​
matrenka [14]

Answer:

The answer to your question is: HCl = 58.44 g

Explanation:

To solve this problem, we must remember the law of conservation of mass that says that, matter cannot be created or destroyed, only changes its form.

That means that, the mass of the reactants must be equal to the mass of the products.

               Process

                    Sodium (Na)  +    Chlorine (Cl)   ⇒     Sodium chloride (HCl)

                         22.99 g              35.45 g                            x

              22.99 + 35.45 = HCl

              HCl = 58.44 g

Match the theoretical motions of particles with their associated phases. Solid, Gas, Liquid. 1. oscillation about a fixed point
viktelen [127]
The correct combination of <span>theoretical motions of particles with their associated phases is given below:

1) Solid : </span>oscillation about a fixed point . Because solids do vibrate (atoms/molecules of a solid oscillate around their mean positions)<span>
2) Gas : </span>translation, vibration, rotation. The gas molecules are free to rotate, oscillate & vibrate. <span>
3) Liquid: </span>rotation and vibration. The liquid molecules are free to rotate & vibrate.
