how do i make chrystals using home suppplies

Explanation:

Crystallography. an arrangement in space of isolated points (lattice points ) in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal.

If an atom experiences sufficient thermal activation, it can move to a neighboring lattice position.4 If the vibration frequency of the atom is v and the atom has Z nearest neighbors, the total number of jump attempts is vZ. However, only a small fraction of the attempts will be successful, with a probability depending on the ratio between the necessary activation energy for a single jump QD and the thermal activation kBT. The effective jump frequency ΓD is then

(5.6)

With each successful jump, the atom travels one atomic distance λ and the total traveling distance in unit time is thus ΓDλ. Substituting the jump frequency ΓD into the expression for the root mean square displacement of a random walker [equation (5.5)] and using the spatial coordinate r leads to

There are six liquid elements present in the periodic table. They are bromine,mercury ,caesium,gallium,rubidium and francium.

The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table.

The gaseous element group; hydrogen (H), nitogen (N), oxygen (O), fluorine (F), chlorine (Cl) and noble gases helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) are gases at standard temperature and pressure (STP).

Explanation:

Answer: We live at the bottom of a gaseous envelope the atmosphere--that is bound gravity to the planet Earth. The circulation of our atmosphere is a complex process because of the Earth's rotation and the tilt of its axis. The Earth's axis is inclined 23.5° from the ecliptic, the plane of the Earth's orbit around the Sun. Due to this inclination, vertical rays of the Sun strike 23.5° N. latitude, the Tropic of Cancer, at summer solstice in late June. At winter solstice, the vertical rays strike 23.5° S. Latitude, the Tropic of Capricorn. In the Northern Hemisphere, the summer solstice day has the most daylight hours, and the winter solstice has the fewest daylight hours each year. The tilt of the axis allows differential heating of the Earth's surface, which causes seasonal changes in the global circulation. On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Air warmed by the Sun rises at the Equator, cools as it moves toward the poles, descends as cold air over the poles, and warms again as it moves over the surface of the Earth toward the Equator. This simple pattern of atmospheric convection.

The theoretical yield is 6 sapphire rings.

This is the total product formed as a result of the complete conversion of

the reactants. In this scenario, the reactant is the 12 sapphires in which 2

of it is needed to produce one sapphire ring.

This however translates to the theoretical yield being 6 sapphire rings

which is gotten by:

2 sapphires = 1 ring

12 sapphires = x

Cross multiply

2x = 12

x= 12/2 = 6 sapphire rings.

Answer:

Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.

Explanation:

The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

The proportion of matter that makes up an object is quantified by its mass. The kilogram, or kg, would be the fundamental SI unit of mass.

Any substance that contains water through the form of H2O molecules is referred to as a hydrate. This water content by weight can vary, but it is typically fixed. The most well-known hydrates seem to be crystalline solids which decompose once the attached water is removed.

Therefore , The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

Answer:

191.4 grams of cinnabar  are required to obtain 165 grams of mercury.

Explanation:

The balanced reaction is:

HgS + O₂ ⇒ Hg + SO₂

By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:

Being the molar mass of each compound:

the following mass amounts of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 200 grams of Hg are formed from 232 grams of HgS , 165 grams of Hg are formed from how many grams of HgS?

[tex]mass of HgS=\frac{165 grams of Hg*232 grams of HgS}{200 grams of Hg }[/tex]

mass of HgS= 191.4 grams

191.4 grams of cinnabar  are required to obtain 165 grams of mercury.

Explanation:

They have to bury the remains in the middle of the forest at the Forensic Osteological Research Center in order to study the decomposition of the dead person. By studying the decomposition of dead person we can get a lot of information which can be used in the study of criminal cases and solving of crimes. The middle place in the forest is a perfect place to bury the remains due to presence of huge amount of microbes as well as insect that helps in the decomposition.

Answer: 2Cr + 3Br2 Yields 3CrBr3

Explanation:

We know that 4a is not balanced because there are 3 Nitrogen atoms on the reactants side and 2 on the products side.

We know that 4c is not balanced because there are 4 Chlorine atoms on the reactants side and 2 on the products side. (Remember there are 2 Cl2 atoms. Therefore, 2 times 2 means there are 4 Chlorine atoms on the reactants side)

Finally, we know the answer is not 4d because there is 1 Potassium on the reactants side and 2 potassiums on the products side.

Therefore, the answer must be 4b, which contains 2 Chromium atoms and 6 bromine atoms on each side

Answer: approximately 15.1 grams.

Explanation: The key to chemistry is to change everything to moles. Then when you have the answer in moles change the answer back to grams, liters, or whatever you want. Change 25 grams of potassium chlorate to moles. Chlorate is Cl with 3 oxygens. ate = saturated. Chlorine has seven valance electrons when it is saturated six of these electrons are used by oxygen ( 2 electrons per oxygen) leaving only 1 electron. 1 K x 39 grams/mole+1 Cl x 35.4grams/ mole+3 O x 16 grams/ mole = 122.4 grams / mole Potassium Chlorate 25 122.4 = moles. 2.05 moles of Potassium Chlorate. There is a 1:1 mole ratio. 1 mole of Potassium Chlorate will produce 1 mole of Potassium Chloride. 2.05 moles of Potassium Chlorate will produce 2.05 moles of Potassium Chloride. Find the gram molecular mass of Potassium Chloride. 1 K x 39 = 39+1 Cl x 35.4 = 35.4 = 74.4 grams / mole. 2.05 moles x 74.4 grams/ mole = 15.2 grams

The mass of O₂ that will be form is 9.8 grams

The chemical reaction is as follows:

2KClO₃ → 2KCl + 3O₂

From the reaction 2 moles of potassium trichlorate decompose to form 2 moles of potassium chloride and 3 moles of oxygen.

Therefore,

molar mass of KClO₃ = 39 + 35.5 + 48 = 122.5 grams

molar mass of O₂ = 32 grams

Therefore,

2(122.5) g of  KClO₃ produces 3(32) grams of O₂

25 g of KClO₃ will produce ? grams of  O₂

cross multiply

mass of O₂  produced = 96 × 25 / 245

mass of O₂  produced = 2400 / 245

mass of O₂  produced = 9.7959

mass of O₂  produced ≈ 9.8 grams

Hello your question is incomplete the pH of the solution is unknown hence I will take the pH of the solution be = 4.7

answer : Pka = 5   i.e. > 4.7

Explanation:

Student titrates :

Unknown weak acid ( HA ) with 25 mL of 0.100 M of NaOH ( to a pale pink phenolphthalein endpoint )  then titrates with  11.0 mL of 0.100 M HCL to the solution that contains neutralized unknown acid

Assuming pH of solution = 4.7

HA + NaOH --------> H2O + NaA

at equilibrium  point

0.1 * 25 * 1 = n * 1  ∴   [tex]n_{ha}[/tex] = 2.5 mmoles ------ 1

also

[tex]A^-[/tex]  + HCL ---------> HA + C[tex]L^-[/tex]

at equilibrium point

[tex]n_{a}[/tex] = 1.1 mmoles --------- 2

The ratio of reaction 2 to 1

[tex]\frac{n_{a} }{n_{ha} }[/tex] = 1.1 / 2.5 ≈ 1/2   ( this show that when the pH = 4.7 approximately half of the A^-  have been converted to HA )

Determine the pKa value of the solution

Given that

pH = Pka + log ( A^- / hA )

4.7 = Pka + log ( 1/2 )

therefore Pka = 4.7 - ( -0.3 ) = 5
