Answer:
wanna waist my points so here
Explanation:
Answer:
Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
Explanation:
We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.
All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.
Answer:
A
Explanation:
2.60 g of CoCl2 was dissolved in water to make 100 mL of solution.
Number of moles of CoCl2 dissolved = mass/molar mass
= 2.60/130
= 0.02 mole
Molar concentration of solutions = number of moles/volume (dm3)
= 0.02/0.1
= 0.200 M
Hence, the molar concentration of thesolution is 0.200 molar.
Correct option = A
Here are my answers since I examined the questions.
Question 1.
No! as a matter of fact, the Rock cycle has no Beginning and No End it's an infinite loop.
Question 2.
The Rock cycle can happen in both ways such as, Volcanic rock melts and cool downs happen quite quickly as in others happen slower.
Question 3.
The 4 Major Steps of the rate of change are, Weathering, Transportation, Deposition, And Compaction.
Question 4.
The main factor for this one would be: The mineral composition of the Parent Rock.
Question 5.
The Parent Rock and the Pressure/temperature conditions.
These all my answers for this project, Good Luck.
