Seismic waves
Explanation:
Seismic waves are disturbances that transmits energy elastically and let's scientist have a glimpse of the interior of the earth.
These waves can pass through any component layer of the earth due to their unique properties.
There are four types of seismic waves but the two body waves are the most important in studying the earth's interior.
- Seismic p-waves can pass through any earth materials as they are longitudinal waves.
- Seismic s-waves are shear waves and can only pass through solids. liquids and gases cannot be sheared.

Yes it is possible because, olymorphismis when two or more crystal structures are possible for a material of given composition. Isomerismis when two or more polymer molecules or repeat units have the same composition, but different atomic arrangements.
Answer: False
Explanation:
1 Cubic centimeter (cm³) = 0.001 liter (L).
Volume of = 10 x 10 x 10 = 1000cm³
To convert cubic centimeters to liters, multiply the cubic centimeter value by 0.001 or divide by 1000.

Preparing a solution of known concentration is perhaps the most common activity in any analytical lab. The method for measuring out the solute and the solvent depend on the desired concentration and how exact the solution’s concentration needs to be known. Pipets and volumetric flasks are used when we need to know a solution’s exact concentration; graduated cylinders, beakers, and/or reagent bottles suffice when a concentrations need only be approximate. Two methods for preparing solutions are described in this section.
It is a simple stoichiometry problem. We have been given with balanced equation and 5.00 moles of HCl and have to calculate the moles of H2.
<span>From the balanced equation it is being clear that 2 moles of HCl are produced by 1 mole of H2. so, 1 mole of HCl will be produced by 1/2 moles of H2. So, the mole ratio of H2 and HCl is 1:2 </span>
<span>to calculate the moles of H2 for the given moles of HCl, multiply the moles of HCl by the mole ratio of H2 and HCl. </span>
<span>5.00 mole HCl x (1 mole H2/ 2 mole HCl) </span>
<span>= 2.50 mole H2 </span>
<span>so, to produce 5.00 moles of HCl, 2.50 moles of H2 are required.</span>
