Answer:
Magnesium ribbon
Explanation:
The mole of a substance is a quantity that contains the Avogadro's number of particles.
This Avogadro's number of particles = 6.02 x 10²³particles
It is known that 1 mole of any substance contains 6.02 x 10²³particles
So, from the given choices, the object with the highest number of moles will contain the highest amount of particles.
Magnesium ribbon with 0.871mole will contain the highest number of particles;
Number of particles = 0.871 x 6.02 x 10²³particles = 5.24 x 10²³particles
Answer:
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
When two negatively charged particles interact with one another, the particles repel with each other. Opposite charges attract while like charges repel. A negatively charged object will exert a repulsive force upon a second negatively charged object. Hope this helps.
Answer: Option (d) is the correct answer.
Explanation:
Steps involved for the given reaction will be as follows.
Step 1: (fast)
Rate expression for step 1 is as follows.
Rate = k
Step 2:
This step 2 is a slow step. Hence, it is a rate determining step.
Step 3. (fast)
Here, is intermediate in nature.
All the steps are bimolecular and it is a second order reaction. Also, there is no catalyst present in this reaction.
Thus, we can conclude that the statement step 1 is the rate determining step, concerning this mechanism is not directly supported by the information provided.
