Ice floats on water. For most other substances, however, the solid sinks in the liquid. Classify each of these statements based
sattari [20]

Answer:

1.High pressure will cause the liquid to become solid :

<u>Describe both water and other substances</u>

2.High pressure will cause the solid to become liquid <u>:</u>

<u>It describe none : neither water nor other substances </u>

<u>This statement is :False for both water and other substances</u>

3.The solid is more dense than the liquid :

It describe other substance

<u>This statement is :False for water but true for other substances.</u>

4. In a phase diagram, the solid-liquid coexistence line has a negative slope.

It describes water:

<u>This statement is :True for water because solid ice is less dense than liquid water.</u>

<u>False for other substance, they have positive slope</u>

5.The molecules are closest in the liquid phase.

<u>This statement is :False for water and other substances </u>

6.The solid is less dense than the liquid:

It Describes water because ice is less dense than liquid water

7. In a phase diagram, the solid-liquid coexistence line has a positive slope.

It describe other substances

<u>This statement is :True for other substances  but false for water</u>

8. The molecules are closest in the solid phase :

<u>Describes both water and other substances </u>

Explanation:

<u>Answers to statement 1 , 2,5 and 8</u>

<u>Answers to statement 1 , 2</u>

On increasing pressure and decreasing temperature , There occur<u> Phase transition</u> always for every substance :

From liquid to solid and gas to liquid

Hence,

In Both for water and other substance

<u>High pressure will cause the liquid to become solid.</u>

<u>Answers to statement 5,8 :</u>

2.The Particles of solid are closely packed hence there is maximum force of attraction between the particle of solid as compared to liquid and gases .

Hence , The molecules <u>of both water and other substance</u>s are closest in the solid phase

This also means that in liquid molecules are far apart .

Rest statement : 3, 4 ,6 ,7 are explained below(see attached image)

<u>The molecules are closest in the liquid phase is false statement  and does not describe both water and other substance</u>

<u>Ice floats on water. For most other substances, however, the solid sinks in the liquid.</u>

This can be explained using the phase diagram of <u>water </u>:

The line DB is  = the solid-liquid coexistence line

It has negative slope because , solid ice is less dense than liquid water . That is why ice floats on water because its density is less than water

Hence <u>Water is described truly by statement 4,6, </u>which are :

4. the solid-liquid coexistence line has a negative slope.

6.The solid is less dense than the liquid.

Rest 3,7 = describe by other substance

<u>other substance</u> : Solid  is more dense than the liquid ,the solid-liquid coexistence line has a positive slope

The reaction 2 ClO2(g) + F2(g) → 2 FClO2(g) is first-order in both ClO2 and F2. When the initial concentrations of ClO2 and F2 a
kupik [55]

Answer:

3. 75.0%

Explanation:

2 ClO2(g) + F2(g) → 2 FClO2(g)

First order with respect to ClO2 and F2.

This means the rate equation is given as;

Rate = k [ClO2][F2]

When the initial concentrations of ClO2 and F2 are equal?

Let's assume an initial value of 1 for both reactants, so rate equation is given as;

Rate = k * 1 * 1 = k

The rate after 25% of the F2 has reacted is what percent of the initial rate?

The concentration left of F2 is 75% ( 100% - 25%) = 0.75

Concentration of ClO2 remains 1.

So rate equation is given as;

Rate = k * 1 * 0.75 = 0.75 k

Comparing 0.75k and k.

This means our answer is;

3. 75.0%
