Answer:
B
Explanation:
A test's power is the probability of correctly rejecting the null hypothesis when it is false; a test's power is influenced by the choice of significance level for the test, the size of the effect being measured, and the amount of data available.
8 Nitrogen, 4 oxygen, 2 N2O
Answer:
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Explanation:
From the given problem, we are to find the factor number by which the volume of the compressed gas has changed through.
We apply Boyle's law to this problem because the condition of the reaction stipulates a constant temperature.
Boyle's law states "the volume of a given mass of gas is inversely proportional to its pressure provided that temperature remains constant". Mathematically, it is expressed as:
P₁V₁ = P₂V₂
P₁ is initial pressure on the gas
V₁ is the initial volume of the gas
P₂ is the final pressure of the gas
V₂ is the final volume of the gas
From the problem, we are to find the factor through which the volume changed:
P₁V₁ = P₂V₂
V₂ = ![\frac{P_{1} }{P_{2} } V_{1}](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%20%7D%7BP_%7B2%7D%20%7D%20V_%7B1%7D)
Now:
P₁ = P₁
P₂ = 4P₁
V₂ = ![\frac{P_{1} }{4P_{1} } V_{1}](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%20%7D%7B4P_%7B1%7D%20%7D%20V_%7B1%7D)
Therefore, the factor of the volume change is ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Chlorine because that element has 17 electrons
Hi,
The answer should be letter C, since a compound is made of atoms of two or more elements, in a defined ratio, bonded together.
