A higher concentration of reactants leads to more collisions per unit time and leads to an increasing reaction rate. Changing the pressure of gaseous reactants is, in effect, changing their concentration. The increased number of collisions caused by a higher pressure generally increases the reaction rate.
Answer:
Lithosphere
Explanation:
All three types of rock make up the Earth's lithosphere, the outermost layer. The lithosphere averages about 100 kilometers in thickness.
the sun cooks the clouds the clouds pee on the earth and all the water falls to earth, pushing all the wind down that's why we have earthquakes
<u>Answer:</u> In heterogeneous mixture, the composition remains variable throughout.
<u>Explanation:</u>
For the given options:
Homogeneous mixtures are defined as the mixtures that appears uniformly throughout the solution and the particle size or shapes are not different. The composition remains constant throughout.
A solution is defined as the solution in which the components gets completely dissolved in it. Particles are evenly spread in these solutions. These solution does not scatter light falling on it. The composition remains constant throughout.
An amorphous solid is defined as the solid in which the constituent particles of the matter are arranged in the random manner. The composition remains constant throughout.
A heterogeneous mixture is defined as the mixture in which component are unevenly spread throughout the solution. The size and shape of the particles differ in these mixtures. These mixture scatter the light falling on it. The composition do not remains constant throughout.
Compound is defined as the chemical specie which is formed by the combination of two or more different type of atoms. <u>For Example:</u> etc...The composition remains constant throughout.
Hence, in heterogeneous mixture, the composition remains variable throughout.
Biotic Resources are based on living organisms. These are obtained from
the biosphere. Examples are animals, birds, forests. They can reproduce
themselves!
Abiotic Resourcesare based on non-living organisms. They are obtained
from lithosphere, atmosphere and hydrosphare. Examples are water, air,
minerals. They cannot reproduce themselves.
