Organometallic Chemical reaction is a Grignard reaction. The critical intermediate (which can be isolated and enables the final product) is the formation of a carbon bond.

The Grignard Reaction is an organometallic chemical reaction that mostly produces C-C bonds. When organic molecules are combined with the Grignard reagent, the Grignard reaction occurs (Rmgx).

The Grignard Reaction is the conversion of an aldehyde or ketone into secondary or tertiary alcohol by the addition of an organomagnesium halide (Grignard reagent). A primary alcohol is produced when formaldehyde and oxygen react.

Alcohol and water molecules have acidic hydrogen atoms that Grignard reagents quickly react with. A proton substitutes the halogen in a Grignard reaction with water, producing an alkane as the end result. Therefore, the Grignard reagent offers a two-step process for changing a haloalkane into an alkane.

The chemical process of food breakdown is called digestion.

Based about how food is digested, mechanical digestion versus chemical digestion is the two main types of catabolism. The digestive system's four important processes are motility, digesting, absorption, as well as secretion.

Digestion enzymes break down food as it moves from the mouth through our digestive system, transforming it into more easily absorbed nutrients. Chemical digestion would be the term for this disintegration. Amino acids as well as reducing sugars undergo a chemical reaction when food is processed and cooked at a high temperature, creating various flavors and brown colors.

Therefore, the chemical process of food breakdown is called digestion.

Hence, the correct answer will be option (c).

Carbon and silicon have same number of valance electrons which is 4 electrons

Now, Barium is a 2nd group element. So, it has two valance electrons.

Silicon is a 16th group element and it has 4 valance electrons as does the carbon. This is because they both stay in the same group in the periodic table.

Neon is a noble gas which has 8 valance electrons and stays in the 18th group.

Therefore, carbon and silicon have same number of valance electrons which is 4 electrons.

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. In a hyperbaric chamber (containing high levels of oxygen) can treat carbon monoxide poisoning, by displacing carbon monoxide from Hemoglobin competitively.

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. This is because, a coordinate bond is formed with Carbon monoxide and Haem structure of the hemoglobin.

Carbon monoxide with Hemoglobin is called as Carboxy haemoglobin.

Presence of oxygen displaces the Carbon monoxide with Hemoglobin that is formed due to poisoning.

Hyperbaric chamber is a chamber which contains pure oxygen in a chamber. The atmospheric pressure is kept about three to four times than the normal, such that the replacement of Carbon monoxide from Haem can occur as fast as possible since this reduces the half life of the Carboxy haemoglobin.

It is advisable not to treat Carbon monoxide poisoning yourself.

At 2000 K, if the partial pressures of an equilibrium mixture of H2S, H2, and S are 0.0151 , 0.0472 , and 0.0352 atm, respectively, then the value of the equilibrium constant Kp at 2000 K is 9.089.

The pressure that is exerted by one among the mixture of gases if it occupies the same volume on its own is known as Partial pressure.

As we know that,

Kp is the constant of a certain reaction at equilibrium.

For the given chemical reaction:

H2 +S -------H2S

The expression of Kp for above equation follows:

Kp = p(H2S) /{p(H2) ×p(S)}

where,

p(H2S) is the partial pressure of H2S = 0.0151atm

p(H2) is the partial pressure of H2 = 0.0472atm

p(S) is the partial pressure of S = 0.0352 atm

Kp = 0.0151/(0.0472 × 0.0352)

Kp = 0.0151/0.00166144

Kp = 9.089

Thus, we find that the value of equilibrium constant Kp at 2000K is 9.089.

Answer:

0.0907 M

Explanation:

Before you can calculate the molarity, you need to convert grams to moles (via molar mass) and convert mL to L.

(Step 1)

Molar Mass (C₈H₅O₄K):

8(12.011 g/mol) + 5(1.008 g/mol) + 4(15.998 g/mol) + 39.098 g/mol

Molar Mass (C₈H₅O₄K): 204.218 g/mol

0.6013 g C₈H₅O₄K             1 mole
------------------------------  x  ------------------  =  0.00294 moles C₈H₅O₄K
                                          204.218 g

(Step 2)

1,000 mL = 1 L

32.47 mL              1 L
---------------  x  -----------------  =  0.03247 L
                        1,000 mL

(Step 3)

Molarity (M) = moles / volume (L)

Molarity = 0.00294 moles / 0.03247 L

Molarity = 0.0907 M

The latent heat of vaporization 5gram of steam converted to liquid at 100°C is 11.3 KJ.

The latent heat of vaporization for a given substance tells you how much energy is required for one mole of that substance to undergo a phase transition or go from a liquid to a gas, at its boiling point.

Joules per gram, an alternative to the more popular kilojoules per mole, are used to express the latent heat of vaporization for water.

Therefore, we must determine how many kilojoules per gram are needed for a certain sample of water to transition from a liquid to a vapor at its boiling point.

As you know, the conversion factor that exists between Joules and kilojoules is 1 kJ = 10³ J

2260 J/g will be equivalent to

                               [tex]2260 \frac{J}{g} . \frac{1kJ}{1000J } = 2.26 kJ/g\\\\[/tex]

As we know,

which means that 2.26 .10³ = 2260J

This is the latent heat of vaporization 5gram of water= 2260J/g × 5g

                                                                                   = 11,300J

                                                                                   = 11.3 KJ

A student makes up 2 l of a 3. 0 m aqueous solution of HBr. to this solution she adds 1 l of a 4 m NaOH solution, then the pH of the resulting solution is 13.83.

Normality is defined as the ratio of equivalent mass of compound to the volume of solution in litre.

N1 is the normality of HBR = 3m

N2 is the normality of NaOH = 4m

V1 is the volume of the HBr = 2l

V2 is the volume of the NaOH = 1l

V is the total volume of solution = V1 + V2 = 2l +1l

= 3l

Normality of the solution = N

As we know that,

N1V1 - N2V2 = NV

3 × 2 – 4 × 1 = N × 3

6 – 4 = N – 3

N = 2/3 = 0.67 m

(OH-) = N = 0.67 m

Since normality of NaOH is greater than BR . Hence the resulting solution is alkaline.

pOH = -log[OH-]

POH = - log (0.67) = 0.17

As we know that,

PH + pOH = 14

pH = 14 – 0.17

= 13.83

Thus, we calculate that the pH of the resulting solution is 13.83.
