Explain the trend in atomic radius as you progress up column 17

A tank containing 550mL of oxygen has a pressure of 3.5atms. If the pressure is changed to standard atmospheric pressure, approx

Zielflug [23.3K]

Answer: the picture is work for number 1,2,4,5,7

Explanation: number 3: as the pressure in the volume decreases, the volume increases causing it to expand and eventually blow.

number 6: because the temperature and the amount of gas don’t change, these terms don’t appear in the equation. What Boyle’s law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half.

hope this helps :))

When iron (III) oxide combines with sulfuric acid H2 S04 the product formed are water and iron (III) sulfate. What is the coeffi

jarptica [38.1K]

Answer:

coefficient 3 is needed t with water molecule to balance the equation.

Explanation:

Chemical equation:

Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O

Balanced chemical equation:

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

The equation is balanced. There are two iron three sulfate six hydrogen and three oxygen atoms are present on both side of equation.

The given equation completely follow the law of conservation of mass.

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Coefficient with reactant and product:

Fe₂O₃ 1

H₂SO₄ 3

Fe₂(SO₄)₃ 1

H₂O 3

So coefficient 3 is needed t with water molecule to balance the equation.

2. The difference between Living and Non-Living Matter are :

Living Matter :

The earth is home to all kinds of plants and animals. They can grow , move and reproduceon their own .
It is natural only .

Non - Living Matter :

Most of the matter in the inverse is non-living. It means that it does not grow, move or reproduce on its own .
It can be natural and non-made.

3. Atom is the smallest particle from which matter is made up of.

4. The one difference between atoms and Molecules are :

Atoms

Atoms may or may not have independent existence
