You wish to analyze the purity of a compound via TLC. If you wanted polar compounds to remain near the bottom (baseline) of the

plate, what kind of TLC plate would you use? (1 pt)
Chemistry

Options:

A reverse phase TLC plate because the nonpolar stationary phase will interact with polar compounds more strongly.

A normal phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.

A reverse phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.

A normal phase TLC plate because the nonpolar stationary phase will interact with nonpolar compounds more strongly.

Answer:A normal phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.

Explanation:TLC(THIN LAYER CHROMATOGRAPHY) is a solid (stationary phase) and a liquid(mobile phase) technique of separation and purity determination that uses the principle of that different compounds have different adsorption rate and different solubility rate to the two phases between which they are partitioned.

ON A DEVELOPED THIN LAYER CHROMATOGRAPHIC PLATE A PURE COMPOUND WILL APPEAR ONLY ON ONE SPOT.

With TLC one can analyse multiple samples at the same time.

Cl2 +2e- —> 2Cl-
aleksandr82 [10.1K]

When two electrons are added to chlorine has, Cl2, each atom of Cl will receive one electron. Hence, the atoms becomes ions having a negative charge, Cl-

<h3>Ions</h3>

Ions are atoms or group of atoms possessing an electrical charge which may be positive or negative.

Negatively charged ions are formed when atoms accept or gain electrons. The negative charge is because there are more electrons than protons in the atom.

Negatively charged ions are usually formed by non-metals. For example, chlorine gas accepts two electrons to become 2 Cl-

Cl2 + 2e- ----> 2 Cl-

Therefore, when two electrons are added to chlorine has, Cl2, each atom of Cl will receive one electron. Hence, the atoms becomes ions having a negative charge, Cl-

What is the outdoor temperature where you are right now?.
rusak2 [61]

The outdoor temperature, also known as the ambient temperature, is a measure of the amount of heat in the environment and this depends on the kind of environment.

<h3>Temperature</h3>

The outdoor temperature around here is about 33 ^oC.

The temperature in the tropical area, where this area belongs, varies between 27 to 35 ^oC with an annual average of about 28 ^oC.

In order words, tropical regions are generally warm, unlike temperate regions.

Tropical regions also have two distinct seasons, the rainy and the dry seasons. This is unlike temperate regions that have summer, spring, winter, and autumn.

What is the molarity of the 8.76 g of Na2S dissolved in 0.500 L of solution?
AlexFokin [52]

Answer:

.224 M

Explanation:

To begin, we need to find the molar mass of Na2S

  • Na=22.99g, S=78.05g
  • 2(22.99)+1(32.07)=78.05

To find Molarity, we use the equation M=moles/Liters of solution

We are given grams, so we must divide by the molar mass of Na2S to find moles.

  • 8.76g Na2S / 78.05g/mol Na2S= .112 moles

Now we use our Molarity equation:

  • .112 moles Na2S / .500L of solution = .224 M
