The normality is the ratio of the equivalent to the volume of the solvent. To the mixture, 1.182 gms of magnesium should be added.

Normality (N) is the grams or moles of solute per liter of solution.

Magnesium has 2 valence electrons in the outermost shell so,

1 mEq of Mg⁻² ions = atomic number of Mg ÷ valence electron

= 12 ÷ 2

= 6 mg

In a liter solution having 197 meq/l of Mg⁻²:

197 meq/l of Mg⁻² × 6 = 1182 mg

Therefore, 1.182 gms of magnesium ions should be added to the mixture.

The compound which on combustion produces Carbon-di-oxide and water is carbohydrates.

Those reaction in which the Crabon present in the reatctant gets reacted with oxygen and produces Carbon-di-oxide.

It is an Exothermic Reaction.

To find out the percentage of C, H and O, we must know about there weight in the product.

Given,

Total weight of compund [Reactant] = 17.41 grams

Weight of carbon dioxide [Product] = 25.61 grams

Weight of water [Product]= 10.48 grams

Now, we need to find out the weight of C,H and O in the products ;

No. of Moles of Crabon =   [tex]\frac{Given \\ weight\\ of\\ the\\ compound}{Molecular\\ weight\\ of\\ the compound}[/tex] x No. of C-atoms in molecule                          

No. of Moles of Crabon =25.61 / 44 = 0.58 x 1 = 0.58 moles

Mass of Carbon = 0.58 moles x 12 = 6.98 gm

No. of Moles of Hydrogen =   [tex]\frac{Given \\ weight\\ of\\ the\\ compound}{Molecular\\ weight\\ of\\ the compound}[/tex] x No. of H-atoms in molecule                          

No. of Moles of Hydrogen =10.48/ 18 = 0.58 x 2 = 1.16 moles

Mass of Hydrogen = 1.16 moles x 12 = 15.08 gm

                                       =   17.41 grams - ( 15.08 gm + 6.98 gm)
Mass of Oxygen  = 4.6 gm

The Newman projection gives the view of the molecule. In molecule A the torsional strain and in B steric strain are present because of the gauche methyl group.

The Newman projection depicts the molecules in the head-on view and uses the letters and the lines to represent the molecule. The torsional strain is because of the molecule's resistance to the twisting.

The steric strain is the Vander wall strain that is due to the forced interaction of the molecules separated by covalent bonds resulting in molecular potential energy.

Answer:

121 million joules energy is released

Explain :

As there are 500 moles of hydrogen gas in a kilogram, this means that burning a kilogram of hydrogen gas releases 500 times as much energy or 121 million joules .

A gas at STP is heated to 35 degree C. The new pressure will be 2.41 atm.

The pressure of the mass of the gas is directly proportional; to the temperature of the gas.

[tex]\dfrac{P_1 }{T_1} =\dfrac{P_2}{T_2}[/tex]

Converting the temperature into kelvin

The initial temperature = 35 °C = 35 + 273 K= 308 K

The final temperature = 50 °C =50 + 273 K = 323 K

Initial pressure = 2.3 atm

Final pressure ?

Putting the values in the equation

[tex]\dfrac{P_1 }{T_1} =\dfrac{P_2}{T_2}\\\\\\{P_2 = \dfrac{P_1 \times T_2}{T_1} \\\\\\\\\\{P_2 = \dfrac{2.3 \times 323 }{308} = 2.41 atm.[/tex]

Thus, the new pressure will be 2.41 atm.

Answer:

See explanation.

Explanation:

This will never naturally occur but you can tweak the system quantum mechanically to temporarily reverse entropy.

The final concentration of a solution that has been diluted by adding 100 ml of water to the original solution is 0.15M.

How to calculate concentration?

The concentration of a solution can be calculated using the following formula:

C1V1 = C2V2

Where;

C1 = initial concentration

C2 = final concentration

V1 = initial volume

V2 = final volume

1.5 × 10 = 100 × C2

15 = 100C2

C2 = 0.15M

Therefore, the final concentration of a solution that has been diluted by adding 100 ml of water to the original solution is 0.15M.

Answer: How much heat it takes to raise the temperature

Specific heat describes how much heat a substance takes to raise the temperature. Hence, Option (c) is correct

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass.

The specific heat capacity of a material is a physical property.

The amount, in grams, that will remain of the isotope will be 2.75 grams

It is the time it takes for a given amount of radioactive substance to decay into half of its original amount.

The half-life is 15 hours. This means that the amount is halved every 15 hours.

If the starting amount is 22 grams, it will become 11 grams (22/2) after the first 15 hours. The 11 grams will become 5.5 grams (11/2) after another 15 hours, making 30 hours.

The 55.5 grams remaining will become 2.75 grams (5.5/2) if another 15 hours should pass, making a total of 45 hours that have passed.

Thus, only 2.75 grams of the isotope will remain in 45 hours.

Answer:

81.08g of H[tex]_{2}[/tex]O will be produced.

Explanation:

Write down the balanced chemical equation:

[tex]B_5H_9 + O_2[/tex] ⇒ [tex]B_2O_3+H_2O[/tex]

[tex]2B_5H_9+12O_2[/tex] ⇒ [tex]5B_2O_3+9H_2O[/tex]

Determine the limiting reagent:

[tex]B_5H_9[/tex] :-    126/63.12646 = 1.995993 mol

               1.995993/2 = 0.9979965

[tex]O_2[/tex] :-         192/31.9988 = 6.000225 mol

               6.000225/12 = 0.50001875

Therefore, [tex]O_2[/tex], is the limiting reagent.

Use stoichiometry ratios to determine the number of moles of water produced:

         [tex]O_2[/tex]         :        [tex]H_2O[/tex]

         12          :          9

  6.000225   :       4,500168756328362

Use the mole formula to calculate the mass of water produced:

[tex]n=\frac{m}{M} \\m=nM\\m=(4.500168756328362)(18.01528)\\m=81.08g[/tex]

Answer:
