Which is a controlled variable in this experiment?

Answers

Answer 1

In Absorption Experiment,

Water location is the independent variable in this experiment.

Room Temperature in the material is dependent variable in this experiment.

Type of a material is a controlled variable in this experiment.

What is Absorption Experiment ?

Absorption experiment is nothing but the experiment of absorption of water in a material (sponge).

Experiment requires vessel, water and sponge.

Processor - take a vessel, pour water into it and dip sponge. take out the sponge. After taking of out sponge, water appears to be decreased from the vessel and sponge gets heavier. When we squeeze the the sponge, water drops down. It is because of water is absorbed by the spouge.

There are number of pores in the sponge, which absorbs the water.

Water location is the independent variable.

In this experiment Room Temperature is dependent variable in this experiment rate of absorption increases with increase in the temperature. decrease in the temperature cause to solidify the water. Type of a material is a controlled variable, we can change type of the material.

What is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution?

Answers

Answer:

D

Explanation:

all ya got to do is divide the moles from the solution... so 3.0 divided by 0.25. put it in a calculator

hope this helps

The molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution is 12M.

What is Molarity?

Molarity of a given solution is known as the total number of moles of solute per litre of the solution.  A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution.

Molarity = (No. of moles of solute ÷ Volume of solution in liters)

The unit of molarity is mol L⁻¹.

Molarity is temperature dependent because as temperature changes, volume of the solution also changes.

Given,

3.0 moles of Saline (NaCl)

Volume of solution = 0.25L

Molarity = (No. of moles of solute ÷ Volume of solution in liters)

Molarity = 3 ÷ 0.25 = 12 M

Therefore, The molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution is 12M.

The first postage stamp, the "Penny Black," was printed and used in England in 1840. The stamp was called the "Penny Black" because it was printed in black ink and was sold for a penny. Mail was sent and received long before the first stamp, but it was the receiver who had to pay for the mail, not the sender. Since some people were unable to pay to receive their mail, the idea of the postage stamp was born.In 1845, five years after England's "Penny Black," the first stamp was printed in the United States of America. Two years later, on July 1, 1847 the first official U.S. postage stamps were issued featuring the portraits of our first postmaster and our first President. The five cent value paid for postal service up to a distance of 300 miles. The stamp, printed in blue, has a catalog value of hundreds of dollars today. A used or canceled copy of this stamp is worth at least half as much as an unused stamp. This stamp was issued imperforate (unperforated) and had to be cut apart with scissors. The adoption of adhesive stamps opened up the development of today's extensive postal system.Since 1845, the United States has printed more than 3,000 different kinds of stamps. Gradually, all of the world's countries began to issue stamps.Several kinds of postage stamps are printed. Some of the most interesting are the commemoratives. A commemorative stamp honors anniversaries, important people, or special events. It is usually on sale at the post office only for a short time.A more common stamp is called a regular issue. Regular issue stamps are printed in greater numbers, and can be obtained for a longer period of time. They are sold in stamp machines as well as in the post office.Other less common stamps are airmail stamps, special delivery stamps, and envelope stamps. If you have ever seen a postage stamp album of the United States, you will know that it has spaces to put all of these stamps.Submit your persuasive writing about stamp collecting.
