4 0
  1. <u>Physical Properties :</u>
  • It is a crystalline colorless solid structure it is soluble in solution such as ether, alcohol, and chloroform but insoluble in water.
  • It is dangerous when it is dry and is very volatile and decomposes when it reaches 103 c.

    2. <u>Chemical Properties :</u>

  • It causes swelling of the skin and undergoes free radical products that are highly reactive.
  • It is irritant when it contacts the skin it breaks down to yield oxygen and benzoic acid.

<u>Explanation:</u>

  • Benzoyl Peroxide is widely used in industry at large scale.
  • It is formed when there is a reaction between hydrogen peroxide and benzoyl chloride.
  • Benzoyl peroxide is used in bread and cheese as the bleaching agent and also used in cosmetics as hair coloring.  
  • Because of its antibacterial property and a peroxide group it is applied to the human skin to treat acne.

A 1.00 L of a solution is prepared by dissolving 125.6 g of NaF in it. What would be the molarity of this solution?
DedPeter [7]

Answer:

2.99 M

Explanation:

In order to solve this problem we need to keep in mind the definition of molarity:

  • Molarity = moles of solute / liters of solution

In order to calculate the moles of solute, we <u>convert 125.6 g of NaF into moles</u> using its <em>molar mass</em>:

  • 125.6 g NaF ÷ 42 g/mol = 2.99 mol NaF

As the volume is already given, we can proceed to <em>calculate the molarity</em>:

  • Molarity = 2.99 mol / 1.00 L = 2.99 M

How many moles of neon atoms are there in a neon sign that has 2.4 * 20^ 24 atoms of neon? *
Whitepunk [10]

Answer:

4 moles of neon

Explanation:

Given data:

Number of moles of neon = ?

Number of atoms of neon = 2.4×10²⁴ atoms

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For given neon atoms:

1 mol =  6.022 × 10²³ atoms

2.4×10²⁴ atoms × 1 mol / 6.022 × 10²³ atoms

0.4×10¹ mol = 4 mol

Elle wanted to test how temperature affects the rate of evaporation. She had three setups:
Pie

Answer:

Temperature

Explanation:

Here the factor that Elle is controlling is the temperature. So temperature here is the independent variable and the dependent variable is the rate of evaporation of water.  Independent variable is controlled during the experiment setup and the outcome of the dependent variable depends on the independent variable.
