Calcium Chloride's chemical formula is CaCl2.
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.
The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are vibrating in place.
As these molecules heat up, they will vibrate more vigorously, and will eventually turn to water, then gas.
<span>1.) Adding CO2 creates a stress on the equlibrium system.which means there will be exothermic reaction in other words more product (i:e H2CO3) will be formed.
</span><span>The equilibrium will shift to the right to offset the applied stress.
</span>
Hence more H2CO3 will be produced. Option A is correct.
2.) Rate = <span>[SO2]2 x [O2] / [SO3]2.
</span>
Hence option C is correct.
Hope this helps!
