Which image represents a homogeneous mixture?
Which image represents a heterogeneous mixture?
Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.
What are Homogenous and Heterogenous mixtures?A homogeneous mixture is defined as having a fairly uniform form and composition, so many homogeneous mixtures are referred to as solutions whereas heterogeneous mixtures are defined as separate substances or phases. The three states or states of matter are gas, liquid and solid.
Some examples of mixtures that include mixtures of sand and water, mixtures of sugar and salt, and mixtures of lime juice and water.
In homogenous solution, particles are distributed uniformly and have uniform composition while in heterogenous solution, particles are distributed non-uniformly and have non-uniform composition
Thus, Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.

4. Water and ethanol have different molecular structures.
5. The lone pairs of electrons in the oxygen atom causes the molecule to be bent; the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges.
[quizlet: captncrun]
Heat is a form factor that changes the solid from light to light to gaseous mediums. The phases take place in a cyclic manner.
The solid to liquid changes take place due to the melting or fusion, solid to gas take lace through the sublimation, liquid to gas is by vaporization, and gas to liquid is condensation. Thus the heat is added and leads to the weakening of the electrical attraction within the molecules.Hence the correct option is C.

which characteristic do valence electrons indicate about reactions between atoms?
Bond number
The characteristic of reactions that depends on valence electrons is the bond type.
In chemistry, a chemical bond could be;
Ionic
Covalent
The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.
When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

Answer:
What is cyclobutane empirical formula : C4H8
Explanation:
Explain, in terms of particles, what happens when methane boils and why
the boiling point of methane is lower than that of butane.
Answer:Butane > ethane > methane, because between bigger molecules there are stronger van der Waals forces and also higher molar mass means they need to be given more energy to have enough kinetic energy to move quickly, freely in gas.
There are multiple butene isomers (Butene) and some (2-Butenes - cis and trans) actually have higher boiling point than n-Butane (there is also Isobutane, of course, with quite much lower boiling point than all of them) and some (1-Butene, Isobutylene) have lower, so this isn't really a fair or simple question. But on simplest level, it can again be said that 1-butene has lower boiling point because it has very similar shape but slightly lower molar mass (2H less) than n-butane.
Explanation:
Intermolecular forces such as dipole-dipole forces, London dispersion forces exist between molecules and these depend on strength of electronegativity of molecule. Therefore, methane converts to gas on boiling due to weak intermolecular forces of attraction between the molecules.
What is intermolecular forces of attraction?Intermolecular forces of attraction is force of attraction that make two molecule come closer. Intermolecular forces of attraction is directly proportional to the electronegativity of the molecule.
Size of electronegative molecule is small so, if any other molecule or molecule come into contact with this molecule then this molecule attract the electron of other molecule very efficiently and therefore the force between the molecule increases.
Molecules of methane have weak intermolecular forces of attraction. When energy is applied, the methane molecules easily break apart and turn into gas.
Therefore, methane converts to gas on boiling due to weak intermolecular forces of attraction between the molecules.

If you have 1 mol xe and 1 mol f₂, how many moles of xef₄ can you create in the following chemical reaction? xe (g) 2 f₂ (g) → xef₄ (g).
The number of moles of XeF4 that can be created would be 0.5 moles.
From the equation of the reactiobn:
Xe (g) 2 F₂ (g) ---> XeF₄ (g)
The mole ratio of Xe to F2 is 1:2. Hence, in the presence of 1 mole Xe and 1 mole F2, F2 would be limiting the reaction.
This means that the amount of F2 would determine the amount of XeF4 that would be produced from the reaction.
The mole ratio of F2 to XeF4 according to the equation is 2:1. This means that for every 1 mole of F2 introduced into the reaction, 0.5 moles of XeF4 will be produced.
In this case, 1 mole of F2 is introduced. Thus, the mole of XeF4 that would be produced would be:
1/2 = 0.5 moles.

How did the scientists create atoms of element 115
Answer:
With ions of calcium in a cyclotron. This produced four atoms of moscovium. Moscovium is a synthetic element with the symbol Mc and atomic number 115. It was first synthesized in 2003 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. In December 2015, it was recognized as one of four new elements by the Joint Working Party of international scientific bodies IUPAC and IUPAP. On 28 November 2016, it was officially named after the Moscow Oblast, in which the JINR is situated.[7][8][9]
Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds.[10] In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen, although it has not been confirmed to behave as a heavier homologue of the pnictogen bismuth. Moscovium is calculated to have some properties similar to its lighter homologues, nitrogen, phosphorus, arsenic, antimony, and bismuth, and to be a post-transition metal, although it should also show several major differences from them. In particular, moscovium should also have significant similarities to thallium, as both have one rather loosely bound electron outside a quasi-closed shell. Over a hundred atoms of moscovium have been observed to date, all of which have been shown to have mass numbers from 286 to 290.

Notice that the bond strength for lithium bonded with any of the anions is larger than the bond strength of potassium bonded with any of
the same anions. Propose a scientifically sound explanation for this.
Select one:
O a. Lithium comes before sodium or potassium alphabetically, so its bond will be stronger.
O b. Sodium and potassium are essential for human metabolism, so they should not bond as strongly with anions.
Oc. Lithium is the smallest cation, so bond length is shorter creating a tighter bond.
Od Lithium is the only cation with a +1 charge.
Check
The bond strength for lithium bonded with any of the anions is larger than the bond strength of potassium bonded with any of the same anions because lithium is the smallest cation, so bond length is shorter creating a tighter bond.
The strength of an ionic bond ultimately depends on the size of the ions. The smaller the ions the stronger the bond and the higher the lattice energy. Such compounds having a high lattice energy tend to deviate from the normal behavior of ionic crystals due to significant covalent contribution.
Lithium is the smallest cation in group 1. Hence, the bond strength for lithium bonded with any of the anions is larger than the bond strength of potassium bonded with any of the same anions because lithium is the smallest cation, so bond length is shorter creating a tighter bond.

You have 505 mL of a 0.160 M HCl solution and you want to dilute it to exactly 0.100 M. How much water should you add
This problem is providing information about the volume and concentration of HCl as 505 mL and 0.160 M respectively, and it is asking for the water that have to be added to prepare a 0.100-M solution.
In such a way, we work over the assumption of constant moles in dilution processes, so that we are able to write:
[tex]M_1V_1=M_2V_2[/tex]
Which relates de volume and concentration at the beginning and end of the experiment. This means we can solve for the resulting volume of the solution as a first calculation:
[tex]V_2=\frac{M_1V_1}{M_2}\\\\V_2=\frac{0.160M*505mL}{0.100M}=808mL[/tex]
Hence, the following amount of water must be added:
