What is the octet rule

BlackZzzverrR [31]

The octet rule is that atoms must have 8 valence electrons to have an octet. Usually, when atoms have an octet, they tend not to bond with any other atoms because they are already stable and do not need to bond anymore.

Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. When samples of these are decomposed, the sulfur dioxide produce

bezimeni [28]

Answer:

For A: The mass of oxygen per gram of sulfur for sulfur dioxide is 0.997 g

For B: The mass of oxygen per gram of sulfur for sulfur trioxide is 1.5 g

Explanation:

For A:

The chemical equation for decomposition of sulfur dioxide follows:

$SO_2\rigtarrow S+O_2$

We are given:

Mass of sulfur = 3.47 g

Mass of oxygen = 3.46 g

To calculate the mass of oxygen per gram of sulfur, we apply unitary method:

For every 3.47 g of sulfur, 3.46 g of oxygen will form.

So, for 1 gram of sulfur, $\frac{3.46g}{3.47g}\times 1g=0.997g$ of oxygen will form.

Hence, the mass of oxygen per gram of sulfur for sulfur dioxide is 0.997 g

For B:

The chemical equation for decomposition of sulfur trioxide follows:

$2SO_3\rigtarrow 2S+3O_2$

We are given:

Mass of sulfur = 5.50 g

Mass of oxygen = 8.25 g

To calculate the mass of oxygen per gram of sulfur, we apply unitary method:

For every 5.50 g of sulfur, 8.25 g of oxygen will form.

So, for 1 gram of sulfur, $\frac{8.25g}{5.50g}\times 1g=1.5g$ of oxygen will form.

Hence, the mass of oxygen per gram of sulfur for sulfur trioxide is 1.5 g

In this thermochemical reaction, what does the coefficient ½ represent?

timurjin [86]

A thermochemical reaction is a chemical reaction with an additional information of the heat of reaction. For example, this is the thermochemical reaction for the combustion of hydrogen gas:

H₂ (g) + 1/2 O₂ (g) → H₂O (l) ΔH = -285.8 kJ

The coefficient 1/2 represents the number of moles of O₂ needed to combust 1 mole of H₂ gas in order to yield one mole of water.

The state of matter in which a material has definite shape and definite volume is the

goldenfox [79]

Answer:

It's a solid.

Explanation:

Solids never change their shape as opposed to gases and liquids. This is because their molecules are tightly packed together. Since all solids have a definite shape, it's volume will also be definite.
