“If a certain metal is cooked, it will conduct electricity better”
- this is a hypothesis, since the statement is kind of vague...”certain metal”...and is written in an “if-then” format.
The amount of electric current that passes through a conductor is directly proportional to the voltage and is described as V = IR
- laws are usually scientific understanding that we’ve tested so much that we’ve come to a conclusion that can often be written out as a mathematical relationship. Hence, the “V = IR”
Electricity is the flow of electric charge in the form of electrons moving through a circuit
- this is a theory. I would give an explanation but I’m out of time.

Here, the rate of reaction would be: rate = k[A]
In short, Your Answer would be Option D
Hope this helps!
Lowery-Bronsted theory is applied here. Acc. to this theory Base accepts protons and Acids donate proton.
Part 1:
Aniline is less basic than ethylamine because the lone pair on nitrogen (which accepts proton) is not localized. It resonates throughout the conjugated system of phenyl ring. Hence due to unavailability of electrons for accepting proton it is less basic compare to ethylamine. In ethyl amine the lone pair of electron is localized and available to abstract proton.
Part 2:
In this case the alkyl groups attached to -NH₂ (in ethylamine) and -O⁻ (in ethoxide are same (i.e. CH₃-CH₂-). Ethoxide is more basic than ethylamine because ethoxide is a conjugate base of ethanol (pKa value of ethanol = 15.9 very weak acid) and the conjugate base of weak acid is always a strong base. Secondly, the oxygen atom more Electronegative than Nitrogen atom can attract more electron cloud from alkyl group as compared to Nitrogen in ethylamine. Hence, oxygen in ethoxide attains greater electron cloud than the nitrogen in ethylamine. Therefore, it is more basic than ethylamine.
Using off road vehicles does help contribute to the process of erosion.
Answer:
Explanation:
Boyle's law for gases states that, at constant temperature, the volume and pressure of a fixed amount of gas are inversely related.
Mathematically, that is:
Here, you have:
Then, you can solve for V₂:
Substitute and compute:
- V₂ = 14.1 KPa × 2.4L / 84.6 KPa = 0.40 L ← answer
