​If 250.0 mL of a 0.96 M solution of acetic acid (C 2H 4O 2) are diluted to 800.0 mL, what will be the approximate molarity of t
adoni [48]

Answer:

0.30M HOAc

Explanation:

Given 250.0ml (0.96M HOAc) => 800ml(??M HOAc)

Use the dilution equation...

(Molarity x Volume)concentrated soln = (Molarity x Volume)dilute soln

(0.96M)(250.0ml) = (Molarity diluted soln)(800ml)

Molarity diluted soln = (0.96M)(250.0ml)/(800ml) = 0.30M HOAc

The representative particle for zinc is the
balandron [24]

Answer: Option B) Atom

Explanation:

An atom is the simplest particle of an element that can retain all the chemical properties of the element, and therefore take part in a chemical reaction.

Thus, an atom of zinc (Zn) represent fully the entire properties of elemental Zinc. For instance: an atom of zinc has a mass of 65.38g.

What do kinetic and potential energy have in common
adell [148]
Just simply... they both are energy.
Use a bow and arrow as an example:
When you pull back an arrow, potential energy or PE is stored in the string and the limbs of the bow.
When you release the the arrow, energy is being transferred from the bow to the arrow. The arrow now has kinetic energy or KE, this means that the energy is being used by the arrow.

silicon, tin, and lead are all in the same group. the density of tin is about 7.28 g/cm3 and the density of lead is about 11.34
Sophie [7]

The atom's radius and mass increase from top to bottom. The density of elements from top to bottom also increases in a periodic table.

Density of Sn= Mass of Sn/Volume of Sn

                     =24.3968/7.28

                     =3.49 g/ml*ml/cm³

                     =3.49 g/cm³

It is accurate to assume that the density of Sn will fall between that of Si and lead .  the mass number and radius of the atoms increase from group to group as we move from top to bottom in a periodic table.. The density rises because the increase in mass number is greater than the increase in radius. Simply multiplying by the molar mass of the gas  allows one to derive the formula for mass density from the formula for number density. Do not forget that the mass is equal to the moles (n) times the molar mass (M).  Smaller masses can be measured in grams instead of kilograms (kg), which is the standard SI unit for mass.
