Answer:Gases and solids , Solids and liquids​

Explanation:

A solid has a definite shape while liquids and gases take the shape of the container in which they are found .

Hence when a substance changes it's state from gas to solid or solid to liquid, it's shape automatically changes as explained above.

horrorfan [7]
The correct answer is:  [C]:  
___________________________________________________________
          "<span>pressure and the number of gas molecules are directly related."
___________________________________________________________
<u>Note</u>:  The conclusion was: "</span> as the pressure in a system increases, the number of gas molecules increases" — over the course of many trials.
          This means that the "pressure" and the "number of gas molecules" are directly related.

Furthermore, this conclusion is consistent with the "ideal gas law" equation:

     " PV = nRT " ; 
____________________________________________________________
in which:

    "P = Pressure" ; 
    "n = number of gas molecules" ; 
___________________________________________________________
        All other factors held equal, when "n" (the "number of gas molecules") 
 increases in value (on the "right-hand side" of the equation), the value for "P" (the "pressure" — on the "left-hand side" of the equation), increases.

How many grams of CO₂ can be produced from the combustion of 2.76 moles of butane according to this equation: 2 C₄H₁₀(g) + 13 O₂
Vilka [71]

Answer:

485.76 g of CO₂ can be made by this combustion

Explanation:

Combustion reaction:

2 C₄H₁₀(g) + 13 O₂ (g) → 8 CO₂ (g) + 10 H₂O (g)

If we only have the amount of butane, we assume the oxygen is the excess reagent.

Ratio is 2:8. Let's make a rule of three:

2 moles of butane can produce 8 moles of dioxide

Therefore, 2.76 moles of butane must produce (2.76 . 8)/ 2 = 11.04 moles of CO₂

We convert the moles to mass → 11.04 mol . 44g / 1 mol = 485.76 g
