Answer:
C. 2.
Explanation:
The total reaction order of this reaction is second order (2). For a second order reaction ,the rate depends on two variable concentration terms which may or may not be same.
Given that:
Two reactants combine to form a product in the reaction A + B → C
The above reaction is bimolecular as two molecules are involved in the reaction.
If and are the concentrations of A and B respectively at any time t, then assuming that the reaction is of first order with respect to both A and B , the overall order is second and the reaction rate is given by:
where;
= specific rate constant for a second order reaction and becomes the rate of the reaction when both and are unity.
Answer:
Molecular formulas indicate how many atoms there are of each element in a compound, while empirical formulas indicate the reduced proportion of elements in a given compound. The molecular formula can be achieved through the empirical formula if the molecular weight of the compound is known, therefore the empirical formula alone cannot be used to obtain the molecular formula.
Explanation:
An empirical formula expresses the relative relationships of the different atoms in a given compound. For example, H2O is made up of two hydrogen atoms and 1 oxygen atom. In the same way, 1.0 mol of H2O is made up of 2.0 mol of hydrogen and 1.0 mol of oxygen. .
The molecular formula for a compound is always the empirical formula. The molecular formula can be obtained from the empirical formula if the molecular weight of the compound is known.
Answer:
A.) DNA is a double helix, and RNA is a single strand.
C.) DNA is involved only in transcription, and RNA is involved in both transcription and translation.
E.) DNA does not have uracil as a nitrogen base, but RNA does have uracil as a nitrogen base.
