If the gases are at the same temperature and pressure, the ratio of their effusion rates is directly proportional to the ratio of the square roots of their molar masses:
<h3>Graham's law of diffusion </h3>
This states that the rate of diffusion of a gas is inversely proportional to the square root of the molar mass i.e
R ∝ 1/ √M
R₁/R₂ = √(M₂/M₁)
Where
- R₁ and R₂ are the rates of the two gas
- M₁ and M₂ are the molar masses of the two gas
From the Graham's law equation, we can see that the ratio of the rates of effusion of the two gases is directly proportional to the square root of their molar masses

Answer:
Independent: The amount of vinegar
Dependent: The dye result on the egg
Controlled: The type of eggs, the size of jars, the dye tablet, how much she stirs, etc.
Explanation:
The independent variable is what is being changed, which in this case, is the amount of vinegar being added to each jar. The dependent variable is what is being measured or observed. Kesha is looking for what happens to the egg when she adds more vinegar with the dye. Lastly, there could be a couple of controlled variables. Like, the dye tablet, the size and brand of the eggs, the types of jars, how long she stirs each egg, and so on. The controlled are just variables kept constant so that any result observed is because of one singular change, the independent variable.
16) 2 servings (4percent Times 2 is 8percent)
17) D; it’s the only choice that can’t be backed up by just looking at the chart
18) A cell wall
19) either A or D but I’m pretty sure it’s D because they help the soil
20) D metabolism
21)c chromosomes because eggs and sperm have 23 chromosomes
