Answer:

27.99 dm³

Explanation:

Applying

PV = nRT................ Equation 1

Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.

From the question, we were aksed to find V.

Therefore we make V the subject of the equation

V = nRT/P................ Equation 2

Given: n = 1.31 moles, T = 37°C = 310K, P = 904 mmHg = (904×0.001316) = 1.1897 atm

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

V = (1.31×310×0.082)/(1.1897)

V = 27.99 dm³

Answer:

moles PbI₂ produced = = 0.9 mole (1 sig. fig.)

Explanation:

Given                   Pb(NO₃)₂  +    2KI     −−>    PbI₂ + 2KNO₃

                                                  300g         ?moles

moles KI = 300g KI/166g/mol = 1.81 mole KI

Rxn ratio for KI and PbI₂ => 2:1

∴ moles PbI₂ produced = 1/2(1.81 mole) = 0.9036144 mole (calculator answer)

= 0.9 mole (1 sig. fig.)

Answer:

Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.

Explanation:

meaning of versatile: capable of or adapted for many different uses, skills, etc. 2 variable or changeable.

The versatile nature of carbon can be best understood with its features such as, tetravalency and catenation. In this section let us learn more about versatility of carbon.

Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.

The two characteristic features seen in carbon, that is, tetravalency and catenation, put together give rise to a large number of compounds. Many have the same non-carbon atom or group of atoms attached to different carbon chains.

Catenation: The property of forming long chains by self-linking with other carbon atoms to form long chains, rings, double or triple bonds is called catenation.

Isomerism: Compounds with same molecular formula but different structural formula are called isomers. An isomerism commonly seen is due to difference in the arrangement of atoms or groups of atoms & is called structural isomerism. The 4 types of structural isomerism are:

 Chain isomerism

 Position

 Functional

Metamerism

Tetravalency: Carbon has 4 electrons in its valence shell. Energy considerations do not allow it to gain or lose 4 electrons; therefore it forms covalent bonds with other elements to complete its octet. This accounts for its tetravalency and explains its ability to form a variety of compounds.

Answer:

[tex]50\; \rm mL[/tex] of the stock solution would be required.

Explanation:

Assume that a solution of volume [tex]V[/tex] contains a solute with a concentration of [tex]c[/tex]. The quantity [tex]n[/tex] of that solute in this solution would be:

[tex]n = c \cdot V[/tex].

For the solution that needs to be prepared, [tex]c = 0.20\; \rm M = 0.20\; \rm mol \cdot L^{-1}[/tex]. The volume of this solution is [tex]V = 250.0\; \rm mL[/tex]. Calculate the quantity of the solute (magnesium chloride) in the required solution:

[tex]\begin{aligned}n &= c \cdot V \\ &= 0.20\; \rm mol \cdot L^{-1} \times 250.0\; \rm mL \\ &= 0.20\; \rm mol \cdot L^{-1} \times 0.2500\; \rm L \\ &= 0.050\; \rm mol\end{aligned}[/tex].

Rearrange the equation [tex]n = c \cdot V[/tex] to find an expression of volume [tex]V[/tex], given the concentration [tex]c[/tex] and quantity [tex]n[/tex] of the solute:

[tex]\displaystyle V= \frac{n}{c}[/tex].

Concentration of the solute in the stock solution: [tex]c(\text{stock}) = 1.00\; \rm M = 1.00\; \rm mol \cdot L^{-1}[/tex].

Quantity of the solute required: [tex]n = 0.050\; \rm mol[/tex].

Calculate the volume of the stock solution that would contain the required [tex]n = 0.050\; \rm mol[/tex] of the magnesium chloride solute:

[tex]\begin{aligned}& V(\text{stock}) \\ &= \frac{n}{c(\text{stock})} \\ &= \frac{0.050\; \rm mol}{1.00\; \rm mol \cdot L^{-1}} \\ &= 0.050\; \rm L \\ &= 50\; \rm mL\end{aligned}[/tex].

Answer:

This molecule is made up of 3 equally spaced sp2 hybrid orbitals arranged at approximately 120o angles. The shape of the orbitals is planar triangular. One orbital contains a lone pair of electrons.

Answer:

im pretty sure its a push or pull thing

Explanation:

Tensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.

Answer:

16.9g

Explanation:Cu+2AgNO3→2Ag+Cu(NO3)2  

Cu will likely have a +2 oxidation state. It is higher in the activity series than Ag, so it is a stronger reducing agent and will reduce Ag in a displacement reaction. Then you need to balance the coefficients knowing than NO3 is -1 and Ag is +1.

Then to calculate the theoretical yield you need to compare moles of the reactants:

m(Cu)=5g

M(Cu)=63.55

n(Cu)=5/63.55=0.0787

By comparing coefficients you require twice as much silver: 0.157mol

n(Ag)=0.157

M(Ag)=107.86

m(Ag)=0.157x107.86=16.9g

Hence, the theoretical yield of this reaction would be 16.9g

Answer:

d. 200.

Explanation:

The reaction is:

2KMnO4 + 16HCl ----> 2KCl + 2MnCl2 + 8H2O + 5Cl2

So 2 moles of KCL are produced form  16 moles of HCL

So 25 moles KCL are made from   25 * (16/2) HCl.

= 25 * 8

= 200 moles. HCl.

Answer:

Amount of Alcohol volume present in solution = 44.99 ml

Explanation:

Given:

Total volume of solution = 409 ml

Amount of Alcohol percentage present in solution = 11%  

Find:

Amount of Alcohol volume present in solution

Computation:

Amount of Alcohol volume present in solution = Total volume of solution x Amount of Alcohol percentage present in solution

Amount of Alcohol volume present in solution = 409 x 11%

Amount of Alcohol volume present in solution = 409 x 0.11

Amount of Alcohol volume present in solution = 44.99 ml

Answer: a) pH = 2.56 , acidic

b) pH = 2.38, acidic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

[tex]pH=-\log [H^+][/tex]

a) [tex][H^+]=2.7\times 10^{-3}[/tex]

Putting in the values:

[tex]pH=-\log[2.7\times 10^{-3}][/tex]

[tex]pH=2.56[/tex]

Thus as pH is less than 7, the solution is acidic.

b) [tex][H^+]=4.1\times 10^{-3}[/tex]

Putting in the values:

[tex]pH=-\log[4.1\times 10^{-3}][/tex]

[tex]pH=2.38[/tex]

Thus as pH is less than 7, the solution is acidic.

Answer:

1,110.48 mL

Explanation:

37°C is 310K and 132°C is 405K

V/V' = T/T'

850/V' = 310/405

V' = (850×405)/310

=> V' = 1110.48 mL

Answer:

its B.)

Explanation:

B.) Light travels in a straight line. :))

Explanation:

a. pressure always favors the side with fewer molecules. in this reaction as both the sides have equal number of molecules, there won't be any change in the position of the equilibrium.

b. when the concentration of the hydrogen gas is increased. more particles would take place in the reaction and so, the rate of reaction would increase favoring the reaction concerning hydrogen gas molecules (backward reaction in this case) therefore, equilibrium would shift to the backward reaction (left).

c. as forward reaction is endothermic, when temperature is increased the equilibrium will shift to the forward reaction (right).

d. catalyst would not have any effect on the position of the equilibrium. it will only increase the rate of reaction.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

[tex]n = \frac{1.00 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{1}{6.02} \\ = 0.166112[/tex]

We have the final answer as
