Answer:

              One nucleophilic center

Explanation;

Nucleophile:

                    Nucleophile is a substance which is nucleus loving in nature (<em>Nucleo</em>; Nucleus , <em>phile</em>; Loving). It is known as a specie which donates a lone pair of electrons to electrophile (electron loving) in a chemical reaction.

                    Thus, Nucleophile is the region of higher electron density in a molecule and attacks on the lower electron density region of another molecule. Also, the nucleophile can also contain a negative charge.

Number of Nucleophilic centers in Methanol:

The chemical structure of Methanol is attached below and it can be observed that the oxygen atom is containing two lone pair of electrons. Hence, the oxygen atom can act as a nucleophilic center. Therefore, there is only one nucleophilic center in methanol.

                        H₃C-OH  +  H₃C-Br     →        H₃C-O-CH₃  +  HBr

In above reaction methanol is acting as a nucleophile and is attacking on electrophilic center (Carbon) of methyl bromide yielding dimethyl ether.

Answer:

There is one nucleophilic center present in methanol.

Further details:

Nucleophile:

Nucleophile is a chemical type that donates an electron pair to form a chemical bond in relation to a reaction. All molecules or ions with an allowed pair of electrons or at least one pi bond can turn as nucleophiles.  

A molecule or ion that contributes a pair of electrons to form a new covalent bond is termed a nucleophile.

Methanol:

Methanol is a liquid chemical with the formula CH3OH (often abbreviated MeOH). It is neutral, unstable, flammable, and poisonous. Methanol is produced from the destructive distillation of wood and is primarily manufactured from carbon monoxide and hydrogen. Its major uses are in organic separation, as a fuel, flush, and antifreeze.

Nucleophilic center in methanol:

If we see the chemical structure of methanol than it can be observed that the oxygen atom is containing two lone pair of electrons. So, an atom of oxygen can turn as a nucleophilic center. Therefore, there is only one nucleophilic center in methanol.

                        H₃C-OH  +  H₃C-Br     →        H₃C-O-CH₃  +  HBr

In following reaction methanol is performing as a nucleophile and is attacking on electrophilic center (Carbon) of methyl bromide yielding dimethyl ether.

30,000 J of heat are added to 23.0 kg of steel to reach a final temperature of 140
kolbaska11 [484]

The initial temperature is 137.34 °C.

<u>Explanation:</u>

As the specific heat formula says that the heat energy required is directly proportional to the mass and change in temperature of the system.

Q = mcΔT

So, here the mass m is given as 23 kg, the specific heat of steel is given as c = 490 J/kg°C and the initial temperature is required to find with the final temperature being 140 °C. Also the heat energy required is 30,000 J.

ΔT =\frac{Q}{mc}

ΔT =\frac{30000}{23 \times 490} = \frac{30000}{11270} =2.66

Since the difference in temperature is 2.66, then the initial temperature will be

Final temperature - Initial temperature = Change in temperature

140-Initial temperature = 2.66

Initial temperature = 140-2.66 = 137.34 °C

Thus, the initial temperature is 137.34 °C.
