Answer:

8

Explanation:

From the question given above, the following data were obtained:

Empirical formula = C₅H₇

Molecular weight = 537 amu.

Number of empirical unit (n) =?

We can obtain the number of empirical units in the actual molecular formula by doing the following:

[C₅H₇]n = 537

[(12×5) + (1×7)]n = 537

[60 + 7]n = 537

67n = 537

Divide both side by 67

n = 537/67

n = 8

Thus, there are 8 empirical units in the molecular formula

What is the IUPAC name for this product?
mihalych1998 [28]

The IUPAC name for the given product is 2 chloro Butane.

<h3>What is IUPAC nomenclature?</h3>

IUPAC stands for 'International Union of Pure and Applied Chemistry', which givers some rule for designing the name of compounds of chemistry.

  • In the given product total four carbon atoms are present and between all of them single bonds are present.
  • In the second carbon atom, chlorine group is present.
  • During the nomenclature process, first we write down the name of the attached group which is followed by the alkane chain.

Hence name of the product is 2 chloro Butane.

How much heat, in joules, must be added to a 75.0-g iron block with a specific heat of 0.449 J/g °C to increase its temperature
svp [43]

Answer:

50,849.25 Joules

Explanation:

The amount of heat, Q, required to raise the temperature of a body with mass, m, and specific heat capacity, c is given by:

Q = mcΔT, where ΔT represents the change in temperature.

In the case of the iron block:

m = 75 g

c = 0.449 J/g °C

ΔT = 1535 - 25 = 1510 °C

Therefore,

Q = 75 g x 0.449 J/g °C x 1510 °C

     = 50,849.25 Joules

<em>Hence, </em><em>50,849.25 Joules </em><em> of heat must be added to  a 75.0-g iron block with a specific heat of 0.449 J/g °C to increase its temperature from 25 °C to its melting temperature of 1535 °C</em>
