Answer:
Thousands to Millions of Years
Explanation:
The rock cycle does not have just one proper direction, there are many pathways for rocks to travel through it. However, for most rocks to be changed from type to another will likely take anywhere from a few million to hundreds of millions of years.
<u>Explanation:</u>
There are 3 states of matter:
<u>Solid state:</u> In this state of matter, the particles are closely packed and they do not have any space between them. Thus, this state of matter has the highest intermolecular forces of attraction between them.
The kinetic energy of the solid particles is the least.
<u>Liquid state:</u> In this state of matter, the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. The intermolecular forces between the particles are less as compared to the solid state.
The kinetic energy of the liquid particles lie in the intermediate of solid and gases.
<u>Gaseous state:</u> In this state, the particles are loosely arranged and have a lot of space between them. Thus, this state of matter has the lowest intermolecular forces of attraction between them.
The kinetic energy of the gaseous particles is the highest.
- <u>Conversion of solid to liquid:</u>
The spacing between the particles increases and so does the kinetic energy. The particles which were closely packed, on getting converted to liquid particles are now present in random and irregular pattern.
- <u>Conversion of liquid to gas:</u>
The spacing between the particles increases and so does the kinetic energy. The particles which were present in irregular pattern, on getting converted to gas particles are now loosely arranged.
Answer: When the concentration of HI is tripled then the rate increases by a factor of 9.
Explanation:
The rate of a chemical reaction is the measure of concentration of reactants or the measure of concentration of products with respect to time.
As the rate of decomposition of HI is given as follows.
When concentration of HI is tripled then the new rate will be as follows.
This shows that rate increases by a factor of 9.
Thus, we can conclude that when the concentration of HI is tripled then the rate increases by a factor of 9.
It is important because it contributes to the movement of your knee
Answer:
D.) 429.73 grams
Explanation:
number of moles x molar mass= mass in grams
3.62 x 118.71= 429.73 grams
