The first eighteen chemical elements on the periodic table are described below in a series of statements. The first 1S letters o

Clarification:

The pertinent information is outlined as follows.

m = 10.0 kg = 10,000 g (since 1 kg = 1000 g)

Starting temperature of block 1, = (100 + 273) K = 373 K

Starting temperature of block 2, = (0 + 273) K = 273 K

Therefore, the heat lost by block 1 equals the heat received by block 2

It's important to convert the temperature into Kelvin as (50 + 273) K = 323 K.

Additionally, the relationship between enthalpy and temperature change is as follows.

=

= 1243550 J

or, = 1243.5 kJ

Next, determine the entropy change for block 1 as follows.

=

=

= -554.12 J/K

Now, the entropy change for block 2 is as follows.

           =

           =

           = 647.49 J/K

Thus, the total entropy is the sum of the entropy changes of both blocks.

                   = -554.12 J/K + 647.49 J/K

           = 93.37 J/K

In conclusion, for this reaction, the outcome is 1243.5 kJ and is 93.37 J/K.

Answer:

To break a single I-I bond, the wavelength of light required is 7.92 × 10⁻⁷ m

Explanation:

The energy needed to break one mole of iodine-iodine single bonds is 151 KJ

The energy necessary to rupture one iodine-iodine bond is calculated as (151 KJ/mol) / 6.02 × 10²³/mol = 2.51 × 10⁻²² KJ

or

2.51 × 10⁻¹⁹ J

Formula:

E = hc / λ    

Where h is Planck's constant    = 6.626 × 10⁻³⁴ js

c is the speed of light = 3 × 10⁸ m/s

λ = wavelength

Solution:

E = hc / λ  

λ   = hc / E

λ   =  (6.626 × 10⁻³⁴ js × 3 × 10⁸ m/s ) / 2.51 × 10⁻¹⁹ J

λ   = 19.878 × 10⁻²⁶ j.m / 2.51 × 10⁻¹⁹ J

λ   = 7.92 × 10⁻⁷ m

Answer:

(A) It can be a fundamentally arbitrary process.

Explanation:

In various human disorders, the natural process of protein folding may malfunction, generally beginning with the formation of a very compact state. This process may also include a systematic decrease in the variety of conformational states and the initial creation of localized structures. Thus, option (A) is the only incorrect statement.

Greetings!

The result is:

The new volume is:

Rationale:

Because the temperature remains constant, we can apply Boyle's Law to solve this issue.

Boyle's Law stipulates that:

Where,

P is the gas's pressure.

V is the gas's volume.

According to the information provided:

Let's put the values into the equation:

Consequently, the new volume is:
