Answer:

= 9.6125M

Explanation:

data:

volume = 800ml

              800/ 1000 = 0.8dm^3

molar mass of NaCl = 23 + 35.5

                                  = 58.5g

mass of NaCl = 450 g

moles= ?

molarity = ?

solution:

no. of moles = [tex]\frac{given mass}{molar mass}[/tex]

                      = 450 / 58.5

                     = 7.69 moles

now, molarity = [tex]\frac{moles}{volume in dm^3}[/tex]

                       = 7.69 / 0.8

         molarity= 9.6125 M

The Ideal Gas Equation

The volume of a gas is directly proportional to the number of moles it contains. Hence, if the number of particles is increased, then the volume inside the container will increase

The hydrogen ion concentration is  [tex]\rm[H^{+} ] = 1.8 \times 10^{-10}[/tex] M .

The pH scale is used to rank solutions in terms of how acidic or how basic they are.

It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution.

These ion concentrations are equal in pure water, which has a pH of 7.

The hydrogen ion and hydroxide ion are related as

[tex]\rm[H^{+} ] = \dfrac{1 \;\times 10^{-14} }{[OH^{-}] }[/tex]

[tex]\rm[H^{+} ] = \dfrac{1 \;\times 10^{-14} }{[5.42\times10^{-5} ] }[/tex]

[tex]\rm[H^{+} ] = 1.8 \times 10^{-10}[/tex] M

Molar mass is the summation of the atomic mass of the individual atoms. The molar mass of KBr•7H₂O is 244.99.

Atomic mass or weight is the number of protons and neutrons in the atom of the individual element. The atomic masses are used to calculate the molar mass of the compound.

The compound KBr•7H₂O: 1 K + 1 Br + 14 H + 7O

Inserting the atomic masses of the individual atoms as:

= 1 (39.09) + 1 (79.90) + 14 (1.00) + 7(16)

= 39.09 + 79.90 + 14.00 + 112

= 244.99

Therefore, 244.99 is the molar mass of KBr•7H₂O.

The final temperature of the sample of gas is 689.65 Kelvin.

Relation between the temperature and pressure will be represented by the ideal gas equation PV = nRT, and for this question required equation is:

P₁/T₁ = P₂/T₂, where
P₁ & T₁ are the pressure and temperature of the initial sample.

P₂ & T₂ are the pressure and temperature of the final sample.

Pressure is in mmHg and on putting values from the question on the above equation, we get

T₂ = (810)(390.8) / (760) = 416.5 degree C = 689.65K

Hence required temperature of the sample is 689.65K.

Explanation:

Manganese metal is produced from the manganese(III) oxide, Mn2O3, which is found in manganite, a manganese ore. The manganese is reduced from its +3 oxidation state in Mn2O3 to the zero oxidation state of the uncharged metal by reacting the Mn2O3 with a reducing agent such as aluminum or carbon. How many pounds of manganese are in 1.261 tons of Mn2O3? (1 ton = 2000 pounds)

About 40 different substances called organophosphorus compounds are registered in the United States as insecticides. They are considered less damaging to the environment than some other insecticides because they breakdown relatively rapidly in the environment. The first of these organophosphorus insecticides to be produced was tetraethyl pyrophosphate, TEPP, which is 33.11% carbon, 6.95% hydrogen, 38.59% oxygen, and 21.35% phosphorus. It has a molecular mass of 290.190.

A quantity can be converted from one unit of measurement to another while maintaining its value. There are 2522 pounds of manganese in 1.261 tons of [tex]\rm Mn_2O_3[/tex].

It is a fundamental idea that is applied in many different disciplines such as science, engineering, math and daily life. To complete a conversion, it is necessary to know the conversion factor – the numerical relationship between the two units of measurement. With the help of this factor, you are able to convert units while keeping the value constant.

To convert tons to pounds we need to know that 1 ton is equal to 2000 pounds.

Given that you have 1.261 tons of [tex]\rm Mn_2O_3[/tex], we can calculate the number of pounds as follows:

Number of pounds = 1.261 tons * 2000 pounds/ton

Number of pounds = 2522 pounds

Therefore, there are 2522 pounds of manganese in 1.261 tons of [tex]\rm Mn_2O_3[/tex].

C. the forward reaction rate is equal to the reverse reaction rate

Chemical equilibrium is dynamic in nature and it can be attained only if the system is a closed one. At equilibrium the forward reaction rate is equal to the reverse reaction rate. The correct option is C.

The state of a system in which the measurable properties of the system do not undergo any further noticeable change under a particular set of conditions is called the state of equilibrium. The properties like pressure, concentration, etc. is constant at equilibrium and remain unchanged thereafter.

An equilibrium can be attained from either direction, i.e., from the direction of the reactants as well as from the direction of the products. At equilibrium the rate of forward reaction is equal to that of the backward direction.

In forward reaction, the reactants are converted into products and in backward reaction, the products are changed into the reactants.

Thus the correct option is C.

An equation that has the same quantity of atoms on both sides of the arrow would be said to represent a balanced chemical reaction.

The given equation is Ca + MgCl2 →

It is known that when Ca is reacted with magnesium chloride ( MgCl2) then it will form calcium chloride (CaCl2 ) and magnesium.

Ca + MgCl2 → CaCl2 + Mg.

It can be seen that, calcium has one atom in the reactant side and one atom in product side. On the other hand, chlorine has one atom in reactant side as well as product side.

Structure 1:
The longest chain is made up of 4 carbons (butane). There is a 1-carbon branch (methyl). The lowest possible position of the branch is on the 2nd carbon. This makes the alkane: 2-methylbutane.

Structure 2:

The longest chain is made up of 7 carbons (heptane). There is a 2-carbon branch (ethyl). The lowest possible position of the branch is on the 4th carbon. This makes the alkane: 4-ethylheptane.

Structure 3:
The longest chain is made up of 4 carbons (butane). There are 2, 1-carbon branches (dimethyl). The lowest possible position of both branches is on the 2nd carbon. This makes the alkane: 2,2-dimethylbutane.
