Answer:
the volume of the sound will quarter
Explanation:
As you move far away from the source, the loudness of sound decreases. This is because as the distance from the source increases, the area it covers also increases thereby spreading the energy over a great area leading to lesser loudness and intensity.
As a result of this, sound intensity follows an inverse square law:
I ∝ 1/d²; where I is the intensity and d is the distance from source.
Therefore If a speaker is moved from 2 feet away to 4 feet away (increment of 2 feet), the volume of the sound would quarter (1/2² = 1/4)
A) Nitrogen has an ATOMIC mass number of 14, but nitrogen gas consists of N₂ molecules, so the mass to use in this problem is 28 g/mol. Rates of effusion ∝ 1/√(mass), so
<span>√(mass unknown) /√28 = (rate N₂ effusion)/(rate unknown effusion) = 1.59 </span>
<span>∴ mass unknown = (1.59)²(28) = 70.78 g/mol </span>
<span>B) One possible gas that comes close for this mass is NF₃.</span>
Ok ok I’ll think it’s.... A? Sorry if it’s wrong!
A) HCL + NaOH = NaCl + H2O
b) CH3COOH + NaOH = CH3COONa + H2O

"ethical issue. A problem or situation that requires a person or organization to choose between alternatives that must be evaluated as right (ethical) or wrong (unethical). ... When considering this problem, lawyers may do well to ignore the letter of the law and realize that it is, at its heart, an ethical issue."
