A colloid has the particles that have the ability to scatter light called the Tyndall effect named after the scientist named Tyndall. A suspension has large suspended particles that settle out at the bottom of the container. A solution has small particles that are evenly distributed throughout. Hence the answer is choice 2.

How do I determine the number of atoms in 30.0 g of K
Alika [10]

The number of atoms in 30.0 g of K would be 4.632  x 10^{23} atoms.

<h3>Avogadro's number</h3>

1 mole of a substance contains 6.022 x 10^{23} atoms.

Mole of 30.0 g of K potassium = 30/39

                                                       = 0.7692 moles

Hence, 0.7692 moles of K would contain

                     0.7692 x 6.022 x  10^{23} atoms.

                                = 4.632  x 10^{23} atoms.

A dichromate solution is standardized by titrating it with a0.1340 M Fe2+ solution. The balanced net ionic equation for the reac
xxTIMURxx [149]

Answer:

<em>8,459x10⁻³ M of Cr₂O₇²⁻</em>

Explanation:

The equation for the reaction of Fe²⁺ with Cr₂O₇²⁻ is:

Cr₂O₇²⁻(aq) + 6Fe²⁺(aq)+14H₃O⁺(aq) → 2Cr³⁺(aq) + 6Fe³⁺(aq)+21H₂O(l)

The moles of Fe²⁺ that you required for a complete reaction of Cr₂O₇²⁻ are:

0,01515 L ×\frac{0,1340moles}{L} = 2,0301x10⁻³ moles of Fe²⁺

By the equation of the reaction, 1 mol of Cr₂O₇²⁻ reacts with 6 moles of Fe²⁺, thus, moles of Cr₂O₇²⁻ are:

2,0301x10⁻³ moles of Fe²⁺×\frac{1molCr_{2}O_{7}^{2-}}{6molesFe^{2+}} = 3,3835x10⁻⁴ moles of Cr₂O₇²⁻

The molarity is:

\frac{3,3835x10^{-4}moles}{0,04L} = <em>8,459x10⁻³ M of </em>Cr₂O₇²⁻

I hope it helps!

) describe the arrangement within energy levels of the seven electrons of an atom of nitrogen.
pantera1 [17]

The arrangement within energy levels of the seven electrons of an atom of nitrogen is  2.5 (that is the first sub shell= 2 while the second sub shell=5)

explanation

In every atom the first energy level can accommodate a maximum of two (2) electrons. The next energy level can accommodate a maximum of 8 electrons. Therefore the seven electron for  nitrogen,  2 electron are put on first sub shell  while other other 5 are putted in the second sub shell.
