Although calcite reacts with HCl amazingly, this reaction is mainly used too identify limestone and dolostone in the field. my suggestion would be to use double refraction to identify calcite. By double refraction when light passes through calcite, it is split into two rays and is refracted twice. I would suggest to take a piece of paper and make a point with pencil, then place the calcite mineral on top of the point and see whether the point splits into two or not. If it does then it is calcite.
Explanation:
Structureless rocks like granite and other intrusive rocks tend to weather into characteristic rounded shapes through this process
Answer:
0.250L of solution. 0.250 moles of solute.
Explanation:
As you can see in the image, there is a beaker with an amount of solution. 1/2L are 500mL and each line of the beaker represents 100mL. That means the volume of the solution is approximately 250mL = 0.250L
Molarity is an unit of concentration defined as the moles of solute per liter of solution. A solution that is 1.000M contains 1.000 moles of solute per liter of solution.
As the volume of the solution is 0.250L, the moles are:
0.250L * (1.000mol/L) = 0.250 moles of solute
Answer:
Hydrogen bond is a <em>special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and electronegative O,N or F atom</em>. The interaction is written:
A-B . . . B or A-H . . . .A
A and B represent O,N or F; A-H is one molecule or part of a molecule and B is a part of another molecule, and the dotted represents the hydrogen bond. So, hydrogen bond is a type of intermolecular forces (attractive forces between molecules, <u>NOT</u> between atoms of the same molecule), and only a few elements can participate on hydrogen bond formation.
<em>Note: dipole-dipole interactions are forces between polar molecules, that is, between molecules that possess dipole moments. </em>
Answer:
<h2>14.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.05 moles</h3>
Hope this helps you
