Explanation:
We are given the following diagram.
In this diagram we can see how the energy in the reaction changes over time. The energy of the products is greater than the energy of the reactants. That means that the products have won some energy. That represents an endothermic reaction where the reactants absorb energy from the surrounding to form the products.
Answer: D. Endothermic reaction.
To determine the empirical formula of the compound, we assume a basis of 100 g of this compound. We calculate as follows:
C = 68.75 g
H = 10.90 g
O = 20.35 g
We convert these mass to moles,
C = 68.75 g / 12.01 g/mol = 5.72 mol
H = 10.90 g / 1.01 g/mol = 10.79 mol
O = 20.35 g / 16 g/mol = 1.27 mol
C = 5.72 mol / 1.27 mol = 5
H = 10.79 mol / 1.27 mol = 8
O = 1.27 mol / 1.27 mol = 1

<span>A-U-G - G-C-A
Met - Ala
If AUG is going to be in the beginning of the chain, </span>A-U-G, also will mean a start codon. For eukaryotes, codon for Met means start of the amino acid chain.
Answer: chemical substance
Explanation:
NaBr will behave more ideally and have an actual freezing point closer to its predicted (theoretical) value.
<h3>What is freezing point?</h3>
The temperature at which a liquid turns into a solid under normal air pressure is known as the freezing point.
NaBr in water dissociates to
and
(two particles) while
dissociating to
two
(three particles). There is a difference between a theoretical boiling/freezing point and an experimentally determined one and the primary cause of this phenomenon is the formation of positive ions on top of negative ones and vice versa, creating an ionic environment with a net opposite charge.
In such a setting we can conclude univalent ions will behave more ideally (bivalent ions have a 'greater' charge and are therefore affecting the solution interactions more). Also, since NaBr dissociates to only two particles, we can conclude it will behave more ideally. Finally, based on these two reasons, we can conclude that out of the two given compounds, NaBr will behave more ideally and have an actual freezing point closer to its predicted (theoretical) value.
