What factors can influence the properties of glass, which include its ability to transmit, reflect, or absorb light, or to be transparent?

Answer · 47 votes

The properties can be influenced by many factors. The most common are the shape of the object, the lighting where the object is located, the environment (colors, shapes, density of other objects, etc.), and the viewing angle of the observer.

Answer: Gases, Liquids, and Solids

Gases

Explanation:

Behavior

gas liquid solid

assumes the shape and volume of its container

particles can move past one another assumes the shape of the part of the container which it occupies

particles can move/slide past one another retains a fixed volume and shape

rigid - particles locked into place

compressible

lots of free space between particles not easily compressible

little free space between particles not easily compressible

little free space between particles

flows easily

particles can move past one another flows easily

particles can move/slide past one another does not flow easily

rigid - particles cannot move/slide past one another

a hypothesis is a prediction based on a theory. If the Hypothesis comes true the theory is more accepted.

A scientific theory differs from a scientific fact or scientific law in that a theory explains "why" or "how": a fact is a simple, basic observation, whereas a law is a statement (often a mathematical equation) about a relationship between facts.

Please tell me if I have made a mistake!!

I enjoy learning from them:)

Answer:

0.32L

Explanation:

Use formula of V= wt/mm•M.
To get this information we need to first get the molar mass (mm).
mm:
K - 2 x 39.09
S - 1 x 32.06
K2S - 110.262 g/mol

Now we plug it back into the equation.
3.5g/ (110.262 g/mol) • (0.100M)
= 0.317 L of solution

To round to the correct number of siginficant figures the answer is.
= 0.32 L

Given what we know, we can confirm that as an ionic compound grows more complex, its melting point will increase.

Therefore, as an ionic compound grows more complex, its melting point will increase due to the increasing number of strong electrostatic forces present in the compound.

Answer:

4.50000 moles

Explanation:

This is dimensional analysis. If there is 163.59 grams in 1 mole of this compound then the converse is true: in 1 mole of this compound there is 163.59 grams --> 1 mol/163.59 grams.

Now that you have your conversion factor:

736.155 grams * (1 mol/163.59 grams) is your equation.

When you multiply these together, grams cancel and you end up with the desired mole-based answer:

4.50000 moles (The extra zeros are to make up for the 6 significant figures in 736.155, feel free to omit them if necessary.)

Answer= C) CN contains a covalent bond.

The compound that has been capable to shift the equilibrium with common ion effect has been  [tex]\rm \bold{Na_2CO_3}[/tex].  Thus, option D is correct.

The complete equation for the decomposition of calcium carbonate has been:

[tex]\rm CaCO_3\rightleftharpoons Ca^2^+\;+\;CO_3^2^-[/tex]

The equilibrium has been the state in the reaction, when the number of products and has been equivalent to the number of reactants. The increase or decrease in the concentration of any of the reactant or product results in the shift in the equilibrium.

For the given reaction, the addition of Calcium or carbonate ions to the solution results in the increase in the product concentration with the common ion effect, and thereby shifts the equilibrium condition.

The ions liberated by the following compounds has been:

[tex]\rm CCl_4\;=\text{not dissolved}\\CO_2\;+\;H_2O\leftrightharpoons CO_3^-\;+\;H^+\\CuSO_4\leftrightharpoons Cu^2^+\;+\;SO_4^2^-\\Na_2CO_3\leftrightharpoons 2\;Na^+\;+\;CO_3^-[/tex]

The compound, that has been capable of liberating the carbonate ions in the medium has been [tex]\rm \bold{Na_2CO_3}[/tex]. Thus, it results in the shift of the equilibrium due to common ion effect. Hence, option D is correct.

The reaction in which Cl has been oxidized is [tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]. Thus, option A is correct.

In a reaction, the oxidation has been defined as the loss of electrons by the atom, while reduction has been depicted as the gain of electrons.

The loss of electrons imparts a positive charge to the atom, while the gain of electrons imparts a negative charge to the atom.

In the following reactions, the Cl has been given as:

The chlorine has loses the electron and is converted to diatomic molecule. Thus, the Cl has been oxidized. The oxidation state of Cl has also been increased from -1 to 0.

The chlorine gains 2 electrons in the reaction and has been reduced.

There has been no change in the oxidation state of chlorine. Thus, Cl has not been oxidized.

The chlorine gains electron and has been converted to the Cl ion. With the gain of electrons, Cl has been reduced.

The reaction in which Cl has been oxidized is [tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]. Thus, option A is correct.

Lift the kitten's tail. The opening just under the tail is the anus. Below the anus is the genital opening which is round in males and is a vertical slit in females. In kittens of similar size, the distance between the anus and the genital opening is greater in the male than the female.

TW: use of inapropate words*

Answer:

not enough information to tell

Explanation:

One way you can tell this difference is the distance between the cat's genitals (organs seen on the outside of the body) and the anus.  A male will have a much greater distance between the genitals and anus than females, 1/2 inch apart on a male kitten and over 1 inch apart on a male adult cat.  However, if the two are almost adjacent on a kitten or less than 1/2 inch apart on an adult, it’s a female.
