2.3 dL = .23 liters. d=deci=10^-1 so you move the decimal place back once.
It's D because micro is 10^-6 (move the decimal place back 6 times) 230,000x10^-6=.23 liters or 2.3 dL.
Answer:
La densidad experimenta una disminución
Explanation:
Hola!
En este caso, debemos recordar que la adición de agua incrementa el volumen donde se encuentra un soluto disuelto, el cual posee una cantidad de materia constante. De este modo, sabiendo que la densidad es:
Al incrementar el denominador (volumen), la densidad experimenta una disminución, al estar en relación inversamente proporcional.
Muchos saludos!
Answer:
The rate decreases as the concentration of the reactants decreases.
Explanation:
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time. This is because a reactant is consumed in a reaction while products builds in that same reaction.
The reaction rate therefore is directly proportional to the concentration of the reactants.
The reaction becomes warmer or hotter as it proceeds. This means that touching the container in which the reaction is taking place would feel hotter. This means the reaction dissipates heat energy and has a negative enthalpy. The reaction is written with a negative delta- H in the products side for the reaction to be balanced.
Answer:
C. It is reactive because it must gain two electrons to have a full outermost energy level.
Step-by-step explanation:
The electron configuration of this element ends in 2s²2p⁴.
A filled energy level would end in 2s²2p⁶.
The element will be reactive, because it must gain electrons to have a full energy level, and it needs two more electrons to do this.
