Answer:

London dispersion forces are the only type of intermolecular forces that nonpolar molecules exhibit.

The molecules in SO2 (g) exhibit dipole-dipole intermolecular interactions.

CH3CH2CH3 has stronger London dispersion forces than does CH4.

Explanation:

London forces result from temporary shifts or distortion in the electron cloud of non-polar molecules. London forces occur in all substances; whether polar or non-polar. However, it is the only kind of intermolecular force in non-polar molecules and noble gases.

Polarity in a molecule stems from difference in electronegativity between the atoms in the molecule. SO2 is a polar molecule due to the magnitude of electronegativity difference between sulphur and oxygen. Hence SO2  exhibit dipole-dipole intermolecular interactions since it is a polar molecule.

The magnitude of London dispersion forces depends on the molar mass and surface area of molecules. CH3CH2CH3  has a higher molar mass and larger surface area than CH4 hence CH3CH2CH3  has stronger London dispersion forces than does CH4.

The following statements which are true include

London forces are the only type of intermolecular force found in non polar

compounds and they are responsible for their attractive interactions.

The molecules in SO2 (g) exhibit dipole-dipole intermolecular interactions as

a result of it being polar.

CH3CH2CH3 has stronger London dispersion forces than does CH4

because it is more non-polar and it is the characteristic attraction found in

non-polar compounds.

Answer:

The time the reaction takes is 12.4s

Explanation:

A reaction that follows the rate law:

Rate =k[A] is order 1 and follows the equation:

Ln[A] = -kt + ln[A]₀

Where [A] is concentration of the reaction after time t: 0.0350M

k is rate constant = 0.15s⁻¹

t is time in seconds

[A]⁰ is initial concentration = 0.225M

Ln[0.0350] = -0.15s⁻¹*t + ln[0.225]

-1.86075 =  -0.15s⁻¹*t

12.4s = t

Answer:

Either direction

Explanation:

If you cook food it would go from cold to hot. If you were to put a drink in the fridge it would go from hot to cold. So it is either direction.

Answer:

See explanation

Explanation:

The equation of the reaction is;

2HNO3(aq) + Ba(OH)2(aq) -------->Ba(NO3)2(aq) + 2H2O(l)

a) The number of moles of  Ba(OH)2  = 225/1000 *  0.200

= 0.045 moles

From the reaction equation;

2 moles of HNO3 require 1 mole of  Ba(OH)2

x moles of HNO3 require 4.50 x 10^2 mol of Ba(OH)2

x = 4.50 x 10^2 * 2/1

x = 9  x 10^2 moles of HNO3

Answer:

Mx will be less than My.

Explanation:

The correct option is - Mx will be less than My.

Because, liquid X have been higher viscosity and vapor pressure than liquid B.

Vapor pressure of liquid A is greater, so the amount of liquid X will vaporized greater and H2 gas has been displaced greater from the beaker as compared to liquid Y.

The amount of H2 in liquid Y remains greater in beaker as compared to liquid X.

So, Mx will be less than My.

Answer:

C) 0.457

Explanation:

The ratio between O2 and H2O is 1:2 according to the balanced equation. You can find how many moles is O2 by : 5.12/22.4 = 0.22857 ( 1 mole = 22.4 litters)

Moles of H2O will be 0.22857 * 2 = 0.457142.

Answer:

Explanation:

The reactant present in more amounts is called excess reagent. In the reaction between Mg and sulphuric acid, the reaction gradually stopped due to the consumption of the acid. Thus, option B is correct.

An excess reagent is a chemical reactant present in more quantity than the other substance or reactant in the reaction. They are not totally consumed after the reaction ends, unlike the limiting reagent.

In the reaction, magnesium is the excess reagent while dilute sulphuric acid is a limiting reagent that determines the reaction rate and the product formation. At first, the reaction will be fast but gradually will become slow as all dilute sulphuric acid will be consumed slowing downs and stopping the reaction.

Therefore, dilute sulphuric acid will be used up at the end of the reaction.

Hello there!

In this case, for the given chemical reaction:

[tex]H_2SO_4+Pb(OH)_4\rightarrow Pb(SO_4)_2+H_2O\\[/tex]

We can see how there is one SO4 on the left and two on the right, thus, we add a 2 in front of H2SO4:

[tex]2H_2SO_4+Pb(OH)_4\rightarrow Pb(SO_4)_2+H_2O\\[/tex]

Next, since there are 8 atoms of hydrogen on the left and two on the right, we add a 4 in front of H2O to obtain:

[tex]2H_2SO_4+Pb(OH)_4\rightarrow Pb(SO_4)_2+4H_2O\\[/tex]

Which is now balanced so the coefficients 2, 1, 1, 4.

Answer: When two hydrogen atoms pair together, they form a  single bond to achieve a complete duet which is a stable configuration.

When two halogens poir together,they form a single bond to achieve a complete octet which is a stable configuration  

When two oxygen atoma pair together, they form a double bond to achieve a complete octet which is a stable configuration

When two nitrogen atoms pair together, they form a triple bond to achieve a complete octet which is a stable configuration

Explanation:

The tendency of atoms to achieve a noble gas configuration that is eight valence electrons is said to be octet rule.  This is done to attain noble gas configuration and stability.

In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained by either by sharing of electrons or complete transfer of electrons.

Hydrogen [tex](H:1s^1)[/tex] has one valence electron each, so sharing of electrons result in formation of single bond and the same electron configuration as the Helium and thus complete its duet.

Halogens [tex](F:1s^22s^22p^5)[/tex]  have 7 valence electron each, so sharing of electrons result in formation of single bond. The stable noble gas configuration is attained and thus complete its octet.

Oxygen [tex](O:1s^22s^22p^4)[/tex]  has six valence electrons each, so sharing of two electrons result in a double bond. The stable noble gas configuration is attained and thus complete its octet.

Nitrogen [tex](N:1s^22s^22p^3)[/tex]  has 5 valence electrons, so sharing of three electrons result in a triple bond. The stable noble gas configuration is attained and thus complete its duet.

Answer:

pH = 6.167

Explanation:

The weak acid, HX, reacts with NaOH as follows:

HX + NaOH → NaX + H₂O

Where 1 mole of HX with 1 mole of NaOH produce 1 mole of NaX (The conjugate base of the weak acid).

Now, using H-H equation:

pH = pKa + log [NaX] / [HX]

Where pH is the pH of the buffer

pKa is -log Ka = 6.167

And [NaX] [HX] are the molar concentrations of each specie

Now, at the neutralization of the half of HX, the other half is as NaX, that means:

[NaX] = [HX]

And:

pH = pKa + log [NaX] / [HX]

pH = 6.167 + log 1

The Lewis base that we can see in the equation is [tex]H_{2} O[/tex]

We have to bear in mind that the Lewis base is the substance that is able to donate a pair of electrons. The substances that is able to accept the pair of electrons is what we call the Lewis acid.

The Lewis acid must possess a space for the addition of an electron pair while the Lewis base would have to be a specie that has a lone pair of electrons or has a negative charge. Thus the water molecule would serve as a Lewis base in this regard.

Answer:

0.202g of Mg(OH)₂ and 0.270g of Al(OH)₃

Explanation:

The OH⁻ ions of the Mg(OH)2 and Al(OH)3 reacts with the HCl. The HCl in excess reacts with the NaOH. To solve this question we must find the moles of HCl that react in the beginning with the antiacid and as the ratio is 1:1 we can find the moles of Mg(OH)2 and Al(OH)3. The reactions are:

OH⁻ + HCl → Cl⁻ + H₂O

HCl + NaOH → NaCl + H₂O

Moles HCl added:

0.03825L * (0.500mol / L) = 0.019125 moles

Moles NaOH utilized:

0.0036L * (0.500mol / L) = 0.0018 moles

Moles HCl that react = Moles OH⁻ in the antiacid

0.019125 moles - 0.0018moles =

0.017325 moles OH⁻ in the antiacid

As the ratio is 1:1. the moles Mg(OH)2 = Moles Al(OH)3

And these 5 hydroxides produce 0.017325 moles:

5X = 0.017325 moles

X = 3.465x10⁻³ moles

Where X are moles of both Mg(OH)2 and Moles Al(OH)3

Mass -Molar mass: 58.3197 g/mol-:

3.465x10⁻³ moles * (58.3197g/mol) =

And

Mass -Molar mass: 78g/mol-:

3.465x10⁻³ moles * (78g/mol) =
