Answer:
Option-D (Acetone is a ketone. Grignard reagents will react with acetone to make an unwanted byproduct.) is the correct answer.
Explanation:
Grignard reagents are formed by reacting alkyl halides in the presence of ether and dry atmosphere at controlled conditions. The rinsing of glassware is not suitable to be done with Acetone. This is because of the reactivity of Grignard reagents towards the carbonyl compounds.
In the scheme below it is assumed that a grignard reagent (ethyl magnesium bromide) was reacted with pentan-2-one to synthesise a tertiary alcohol (3-methylhexan-3-ol). But when the glassware is rinsed with acetone, some acetone left in glassware (like Round bottom flask) will react with the grignard reagent and will produce corresponding tertiary alcohol (2-methylbutan-2-ol in this assumption).
Answer:
1.35×10¹² μg
Explanation:
Mass (Kg) = 1350 Kg
Mass (μg) =?
Thus, we can obtain the mass of the adult rhino in micrograms (μg) by converting 1350 Kg to microgram (μg) as follow:
1 Kg = 1×10⁹ μg
Therefore,
1350 Kg = 1350 kg / 1 kg × 1×10⁹ μg
1350 Kg = 1.35×10¹² μg
Therefore, 1350 Kg is equivalent to 1.35×10¹² μg.
well yah .... homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions.
while on the other hand ...A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
there are many differences between these two .... but fr a basic info .... i guess what i said would help .....
No they are not, as climate is long term conditions for an area while weather is temporary
