baherus [9]3 years ago
8 0

The answer is: 60.

Tobacco products are made up of thousands of chemicals, including at least 60 known to cause cancer (carcinogens).

Some of carcinogens chemicals are: acetaldehyde, arsenic, radioactive elements (for example polonium-210), nitrosamines, nickel, benzene, polycyclic aromatic hydrocarbons, vinyl chloride.

Smoking tobacco causes at least 15 different types of cancer. For example: mouth, pharynx, larynx, oesophagus, liver, pancreas, stomach, kidney cancer.

A student weighs out a 7.24 g sample of , transfers it to a 300. mL volumetric flask, adds enough water to dissolve it and then
velikii [3]

The molarity of the zinc chloride solution will be 0.089 M

<h3>Molarity</h3>

Mole of 7.24 g ZnCl2 = 7.24/136.286 = 0.5312 mol

Total volume of water used in preparing the solution = 300 + 300 = 600 mL

Molarity of the solution = mole/volume = 0.5312/0.6 = 0.089 M

The molarity of the zinc chloride solution is, therefore, 0.089 M

Solution A is 100 times as acidic as solution B. What is the difference in pH values of solution A and solution B
devlian [24]

Answer:

The difference is 2 pH units.

Explanation:

Let's give an arbitrary value to the H⁺ concentration of solution A, [H⁺]ₐ:

  • [H⁺]ₐ = 0.001 M

If that's the case then the pH of solution A would be:

  • pHₐ = -log(0.001) = 3

----

The H⁺ concentration of solution B ( [H⁺]ₓ ) is 100 higher than that, so:

  • [H⁺]ₓ = 0.001 * 100 = 0.1 M

And its pH:

  • pHₓ = -log(0.1) = 1

So the difference in pH values is:

  • pHₐ - pHₓ = 3 - 1 = 2

A sample of nitrogen gas has a pressure of 7.58 kPa at 639 K. What will be the pressure at 311 K if the volume does not change?
omeli [17]
Over here you have to use the formula: <span>P1/T1= P2/T2
P1= 7.58
T1= 639

P2= ?
T2= 311

</span><span>7.58/639 = ?/311
</span>= 3.689 kPa
