If the value for ΔS is postive, and the value for ΔH is negative, thr reaction will be
dmitriy555 [2]

It follows that the reaction is spontaneous at high temperatures Option A.

<h3>What is ΔS ?</h3>

The term ΔS is referred to as the change in the entropy of the system. Now recall that entropy is defined as the degree of disorderliness in a system. If a system is highly disorderly then it means that it has a high entropy. Also, ΔH has to do with the heat change that accompanies a reaction.

We know that both the entropy and the heat change can both either be positive or negative. Now we know that the equation ΔG = ΔH - TΔS can be used to ascertain whether or not a reaction will be spontaneous. If the result is negative, then the reaction will be spontaneous.

As such, when then it follows that the reaction is spontaneous at high temperatures Option A.

The 30.6-g sample of the compound X2O3 contains 14.4 g of oxygen atoms. What is the molar mass of element X?
mars1129 [50]
X₂O₃ ===> 3 moles of oxygen == > 48 g O

Molar mass of X₂O₃-------------- 48g O
30,6g --------------------------------- 14,4g

Molar mass = (30,6×48)/14,4
Molar mass = 102g

Molar mass of X₂ = 102 - 48 = 54g
Molar mass of X = 54/2 = 27g

X ==> 27 g/mol ==> Al
X₂O₃ ==> Al₂O₃

if a gas has a volume of 2.60 L at a pressure of 1.60atm, what will its new volume be at a pressure of 10.6 atm
cricket20 [7]

Answer:

0.39L

Explanation:

Given parameters:

Initial volume of gas V₁ = 2.6L

Initial pressure on gas P₁ = 1.6atm

Final volume of gas V₂ = ?

Final pressure on gas P₂ = 10.6atm

Solution

Applying Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

                      P₁V₁ = P₂V₂

                      V₂ = \frac{P_{1}V_{1} }{P_{2} }

                      V₂ =  \frac{1.6 x 2.6 }{10.6 } = 0.39L

State the postulates of Dalton's atomic theory. ​
horrorfan [7]
A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates: (1) Elements consist of indivisible small particles (atoms). (2) All atoms of the same element are identical; different elements have different types of atom. (3) Atoms can neither be created nor destroyed.

The size of the gas particles compared to the overall volume of the gas is 22.4 L
jeka57 [31]
Well. Yeah. Basically.

1 mole of any gas is 22.4 L. 

Not really sure if that answers your question but that's what i know. 
Anyway if we are talking about the size then usually gases are filled with empty space.
