D. layer B is younger than layer G.
Answer:
3.60 ml
Explanation:
First of all we must put down the equation of the reaction. This will serve as a guide to our solution;
KOH(aq) + HBr(aq) -----> KBr(aq) + H2O(l)
The following were given in the question;
Concentration of acid CA= 2M
Volume of acid VA= 18ml
Concentration of base CB= 0.01 M
Volume of base VB= ????
Number of moles of acid NA= 1
Number of moles of base NB= 1
From;
CAVA/CBVB = NA/NB
CAVANB= CBVBNA
Therefore;
VB= CAVANB/CBNA
Substituting values;
VB= 2 × 18 ×1 / 0.01×1
VB= 3.60 ml
Therefore; 3.60 ml of base was used.
Answer:
Compound: A substance that is made up of more than one type of atom bonded together.
Mixture: A combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.
Explanation:
The different substances in a mixture are not chemically combined, whereas the different elements in a compound are. The atoms do not combine in the mixture, but they combine when they form a compound.
Answer:
In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. The term metamer was formerly used for the same concept.

¡Hola!
En este caso, teniendo en mente la definición de ley de velocidad, es posible recordar que esta tiene la forma genérica:
![r=k[A]^m](https://tex.z-dn.net/?f=r%3Dk%5BA%5D%5Em)
En donde k es la constante de velocidad, [A] la concentration de cualquier especie A en la reacción y m el orden the reacción. Ahora, hay tres órdenes de reacción, cero, primer, y segundo orden, y esto pasa cuando m=0, m=1 y m=2 respectivamente. Por lo tanto, si la reacción es de orden cero, la rapidez de reacción resulta igual a la constante de velocidad dado que la concentración estaría elevada a la cero y por consiguiente siempre tendrá valor de 1, por lo que la concentración no afecta la velocidad de reacción. Esto anterior se expresa como:
![r=k[A]^0\\\\r=k](https://tex.z-dn.net/?f=r%3Dk%5BA%5D%5E0%5C%5C%5C%5Cr%3Dk)
