Lab 2: paper chromatography of organic dyes Picture of questions below.

Chemistry
1 answer:
Anika [276]2 years ago
7 0

Answer:

The three primary colors used when mixing dyes or paints are red, yellow, and blue. Other colors are often a mixture of these three colors. Try running a chromatography test again with non-primary-color markers, like purple, brown, and orange.

Explanation:

<h3><em>Mixtures that are suitable for separation by chromatography include inks, dyes and colouring agents in food. ... As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out.</em></h3>

A rock is found to contain 2.2 grams of uranium-235, a radioactive isotope. If the rock has undergone 2.75 half-lives, what was
Verizon [17]

Answer:

=14.8 grams

Explanation:

The remaining amount is normally calculated using the formula:

Remaining mass= 1/2ⁿ × Original mass where n is the number of half-lives.

Therefore, original mass= Remaining mass × 2ⁿ

Remaining mass= 2.2 grams

Number of half lives= 2.75 half lives

Original mass= 2.2g × 2²·⁷⁵

=14.8 grams

If the heat of fusion for water is 334 j/g, how many Jules are needed to melt 45.0 g of ice at 0.0°c?
finlep [7]

Given parameters:

Heat of fusion of water  = 334j/g

Mass of ice  = 45g

Temperature of ice =  0.0°c

Unknown:

Amount of heat needed to melt = ?

Solution:

This is simply a phase change and a latent heat is required in this process.

  To solve this problem; use the mathematical expression below;

             H  = mL

where m is the mass

            L is the heat of fusion of water;

              H  = 45 x 334  = 15030J
