Answer:
Explanation:
Hello,
In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:
By knowing the volume and the concentration of the NaOH, one obtains:
Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:
Best regards.
Answer:
I might be wrong i'm not sure
Explanation:
Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.
Answer:
The claim is untrue.
Explanation:
Given the information from the question. We need to evaluate the claim.
According to the phase rule we have F= C-P+2
In this particular situation, the forms are completely allotropic .In order words, they are conjured through the same chemical composition. Thus constituents C= 1, P=4 for four phases and the number variables is 2. As a result, F= C-P+2 =1-4+2= -1. Therefore, the claim is untrue.
Answer:
expande
forman se alejan
Explanation:
Según las leyes de los gases ideales;
La ley de Charles establece que el volumen de una masa dada de gas ideal es directamente proporcional a su temperatura a la presión simultánea.
Esto significa que cuando se calienta una masa dada de gas ideal, el gas se expande y las moléculas de gas se alejan unas de otras de acuerdo con la ley de Charles.
