Answer: Option (a) is the correct answer.
Explanation:
Elements which are most electropositive or electronegative are the most reactive in nature. Therefore, they are active.
Elements of group 1 are also known as alkali metals. Elements of group 1 are lithium, sodium, potassium, rubidium, cesium, and francium.
All these are highly electropositive in nature and thus, are active. These are placed at the top left column of periodic table.
Thus, we can conclude that out of the given options, the most active metals on the periodic table are found on the lower left.
Answer:
Increased
Explanation:
We know that the higher the temperature the higher the rate of reaction. This implies that as the temperature is increased, a reaction tends to proceed faster.
This follows from the collision theory, the higher the temperature, the higher the energy of the reacting particles hence they collide with each other faster and more effectively.
Thus the rate of reaction( or reaction time) for the carton of milk on the counter was increased.
Answer:
En lugar de utilizar las ya conocidas unidades de concentración, para la solubilidad es más común emplear la siguiente: Medimos la solubilidad como la cantidad de gramos del soluto que podemos disolver en 100 gramos de disolvente.
Explanation:
Organ system, because there are multiple organs that work together to help make the body function.
