Why are gas volumes the same?According to Avogadro's hypothesis, all gases have an equal number of particles in an equal volume at a given temperature and pressure.The actual particle size themselves is almost negligible because the majority of a gas's volume is made up of the void space between its particles.

In general, how can you determine the mass number of the daughter product after alpha decay has taken place? how can you determine the atomic number?.
to determine the mass number of the daughter product after alpha decay has taken place Subtraction of 4 from the parent element yields the mass of the daughter product. Subtraction of 2 from the parent atom yields the atomic number of the daughter product.
Assume X is a parent element with atomic number Z and mass number A; if X decays, we obtain a daughter element Y with atomic number Z1 and mass number A1, as well as an alpha particle with atomic mass 2 and mass number 4. An alpha particle is a doubly ionised Helium atom with atomic number 2 and mass number 4.

A
solution of NaOH contains.
11.6 grams of solute to 150cm³ of
solution. What is the molarity
of
the solution?
Answer:
1.93 molar, or M
Explanation:
By definition, molarity is defined as moles/liter. A 0.5 molar (or M) solution will have 0.5 moles of solute per 1.0 liter. To answer this question, first calculate how many moles of NaOH there are in 11.6 grams of the compound. We'll need the miolar mass of NaOH, which is 40 grams/mole. This is found by adding the atomic masses of each atom in the compound:
Na: 23
O: 16
H: 1
Total: 40 g/mole
The moles of NaOH is found by dividing the mass by the molar mass:
(11.6 grams NaOH)/(40 g/mole NaOH) = 0.29 moles NaOH
0.29 moles NaOH is contained in 15cm^3 of solution. Convert 15cm^3 into liters (L):
(15 cm^3)*(1 ml/cm^3)*(1 liter/1000 ml) = 0.015 liters
cm^3 and ml both cancel with these conversion factors, leaving only liters, L.
The solution consists of 0.29 moles of NaOH in 0.15L. It's concentration is therefore:
(0.29 moles)/(0.015L) = 1.93 molar, or M

Under very low temperature or high pressure the gases behave the most ideally.
A theoretical gas known as an ideal gas is made up of several randomly moving point particles with no interparticle interactions. [1] Because it abides by the ideal gas law, a condensed equation of state, and is amenable to statistical mechanics analysis, the ideal gas concept is helpful. If, for instance, the interaction is totally elastic or is thought of as point-like collisions, the constraint of zero interaction can frequently be disregarded.
Many real gases behave qualitatively like an ideal gas under various temperature and pressure settings, where the gas molecules (or atoms for monatomic gases) take on the function of the ideal particles.

A sample of 6.81 moles of cesium fluoride is
reacted with 8.23 moles of xenon hexafluoride
to produce cesium xenon heptafluoride. Using
the balanced equation below, calculate the
maximum amount in moles of cesium xenon
heptafluoride that can be produced.
CsF+XeF6- CsXeF7
Answer:
6.91 moles cesium xenon heptafluoride
Explanation:
The balanced equation
CsF + XeF6 = CsXeF7
tells us that we should expect 1 mole of cesium xenonheptafluoride (CsXeF7) for every 1 mole of cesium fluoride consumed, a molar ratio of 1:1. It also says we will use 1 mole of xenon hexafluoride, XeF6, for each mole of cesium fluoride.
The 6.91 moles of CsF will therefore require 6.91 moles of XeF6 to completely react. We are in luck, since there are 8.23 moles of XeF6, more than enough to react with all the CsF. In fact, there should be (8.23 moles - 6.91 moles =) 1.32 moles of XeF6 left over, unreacted. CsF is the "limiting reagent:" the reaction will stop once it is consumed. We can assume that all of the CsF will react, so that will result in the same number of moles of CsXeF7 produced, since the molar ratio of the two is 1:1 reactant/product.

The increase in energy when tetrahedral bond angles deviate from the optimum angle of 109.5 degree is known as angle strain.
In cycloalkanes, the carbon atoms are sp3 hybridized, which would imply an ideal tetrahedral bond angle of 109.5 degree whenever possible. cycloalkanes look like shapes such as a triangle, square, tetrahedral. all the rings are in a flat or planar shape. Bayer Theory suggests that the difference between the ideal bond angle (which is 109.5° for sp3 carbon) and the angle in the planer cycloalkane causes the strain, which is called angle strain. According to the Bayer Theory, cyclopentane would be the most stable because its bond angle, 108°, is closest to the ideal angle of 109.5°. Cyclopropane would be the least stable one since it has the largest angle deviation of 49.5° (60° vs 109.5°). It was also predicted that cyclohexane would be less stable than cyclopentane because of the larger angle deviation (10.5° deviation for cyclohexane vs 1.5° for cyclopentane), and as the number of sides in the cycloalkanes increases beyond six, the stability decreases.

Write the formula unit equation for this reaction occuring in water: Barium perchloate and sodium sulfate are mixed to form sodium perchlorate and barium sulfate.
1. Na2SO4(aq) + Ba(ClO)2(aq) → 2 NaClO(aq) + BaSO4(s)
2. Na2SO4(aq) + Ba(ClO3)2(s) → 2 NaClO3(aq) + BaSO4(s)
3. Na2SO4(aq) + Ba(ClO3)2(aq) → 2 NaClO3(aq) + BaSO4(s)
4. Na2SO4(aq) + Ba(ClO4)2(aq) → 2 NaClO4(s) + BaSO4(aq)
5. Na2SO4(s) + Ba(ClO4)2(aq) → 2 NaClO4(s) + BaSO4(aq)
6. Na2SO4(aq) + Ba(ClO4)2(s) → 2 NaClO4(aq) + BaSO4(s)
7. Na2SO4(aq) + Ba(ClO4)2(aq) → 2 NaClO4(aq) + BaSO4(s)
The formula unit when barium perchlorate reacts with sodium sulfate to produce sodium perchlorate and barium sulfate would be: [tex]Ba(ClO_4)_2 (aq) + Na_2SO_4 (aq) -- > 2NaClO_4 (aq) + BaSO_4 (s)[/tex]
Chemical reactionThe reaction between barium perchlorate and sodium sulfate to produce sodium perchlorate and barium sulfate is a double decomposition reaction whose chemical equation can be derived as follows:
Formula for sodium sulfate = [tex]Na_2SO_4[/tex]
Formula for barium perchlorate = [tex]Ba(ClO_4)_2[/tex]
Formula for sodium perchlorate = [tex]NaClO_4[/tex]
Formula for barium sulfate = [tex]BaSO_4[/tex]
Since barium sulfate is insoluble, the chemical equation for the reaction would be:
[tex]Ba(ClO_4)_2 (aq) + Na_2SO_4 (aq) -- > 2NaClO_4 (aq) + BaSO_4 (s)[/tex]
In other words, a double decomposition reaction can also be a precipitation reaction in which two aqueous salts exchange radicals to produce one aqueous and one insoluble salt.

what atomic or hybrid orbitals make up the sigma bond between and in acetic acid, ch3cooh ? ( is the second carbon in the structure as written. is the first oxygen in the structure as written.) orbital on orbital on what is the approximate c1-c2-o1 bond angle? angle
An sp2 hybrid orbital from the carbon-1 and the same from the oxygen-1 atoms combine to form the sigma bond between them.
The bond angle is approximately 120°.
The carbon-1 atom is the carbon attached to the two oxygens and the other carbon of the methyl functional group. The oxygen-1 is the carbonyl oxygen that has a double bond to carbon-1. This double bond is made up of one sigma bond and on pi bond. In order for the carbon to be attached to three atoms and be stable requires sp2 hybridization to form single bonds to the three attached atoms leaving one p-orbital available to make the pi-bond part of the double bond. Oxygen also is sp2 hybridized with the other two hybrid orbitals occupied by two pairs of nonbonding electrons. The molecular geometry associated with sp2 hybridization is trigonal planar which is flat triangular in shape with carbon-1 being in the middle. The bond angle formed between carbon-2/carbon-1/oxygen-1 will be 120° as will be the angles between carbon-2/carbon-1/oxygen-2 and oxygen-1/carbon-1/oxygen-2.
