Answer:
B
B
Explanation:
the both have the same thing or something
Answer:
- <u><em>The first statement is false: a.At equilibrium, equal amounts of products and reactants are present. ΔG° is a function of Keq.</em></u>
Explanation:
When one part of a statement is false, the whole statement is false.
At <em>equilibrium,</em> the amounts of products and reactants does not have to be equal.
At equlibrium the rates of the forward reaction and the reverse reaction must be equal.
An equilibrium reaction may be represented by:
That represents two reactions:
- Direct reaction: A + B → C + D (A and B yield C and D)
- Reverse reaction: A + B ← C + D (C and D yield A and B: note that the arrow goes from right to left)
So, it is when the direct and the forward rates are equal that there is not net change in the amounts of all the species and so the reaction is is equilibrium).
As per the other statement, both parts are true:
- When reactants become products, they do so through an intermediate transitrion state: when the reactants approach each other and collide with enough energy and appropiate position, the bonds start to break and the bonds of the products start to form. This is the transition state.
- Most biocatalysts are proteins: enzymes are simply proteins, with specific structures, that may accelerate or even deceralate biochemical reactions.
The correct answer is option B. The amphibian and mosses belonged to the same age.
Since the rocks belong to the same age and one contain fossils of an amphibian and the other containing fossils of mosses, it is very likely that both the amphibian and the mosses existed at the same time.
Sedimentary rocks generally have fossils in them and it is very easy to determine the age of the fossils from Radiometric Dating using radioactive carbon C¹⁴. However, before the complete understanding of radioactive decay fossil, age was determined by studying the succession of fossils on old to younger sedimentary rocks.
Some elements that are not abbreviated with one or two letters on the periodic table are Ununoctium (Uuo) and Ununtrium (Uut).
Answer: Water. H2O
Explanation: a chemical compound is composed of many identical molecules made from more than one element, in this case Hydrogen and Oxygen.
