True or FalseWhen comparing an empirical formula to a molecular formula the subscripts after each element in both formulas are the same

Answers

Answer: That's true.

Explanation:

If a single atom of an element in a molecule required a subscript,

then water would be  H₂O₁ , and salt would be  Na₁Cl₁ .

The doldrums region on Earth is created by an amount of heating from the Sun that results in the rising of warm, moist air, low air pressure, cloudiness, high humidity, and numerous forms of severe weather, such as thunderstorms. Hurricanes originate in this region. The doldrums are also noted for calms, periods when the winds disappear, trapping sailing vessels for days or weeks. Where are the doldrums found?

What happens in this reaction?

butan-1-amine + CH3I -->

Answers

Here we have to get the product between the reaction of butane-1-amine with methyl iodide (CH₃I).

The  reaction between 1 mole of butan-1-amine and 1 mole of methyl iodide produces Methyl-butamine which is a secondary amine.

However, In presence of 2 moles of methyl iodide the reaction proceed to N, N-di-methylbutamine. The reaction is shown in the figure.

This is one of the effective reaction method to generate secondary and tertiary amine from primary amine.

The primary amine reacts with alkyl iodide to form secondary to tertiary amine. The final product depends upon the quantity of the alkyl iodide present in the reaction.

Answers

so it would be the complimentary base pairing, meaning that the codon must have been:
GAC
(Which is the codon for aspartic acid)
It would be GAT for the first one and GAC for the second.

Suppose you are digging a hole in the ground. You notice that the soil is in two layers. Each layer has particles of different sizes. You observe the soil closely and find that the bottom layer is made up mostly of sand and the top layer is made up mostly of clay. What do you think caused the soil to have two different layers?
