The state of water is determined solely by the conditions of _____.

Chemistry

Arlecino [84]3 years ago

Answer:

The state of water is determined solely by the conditions of pressure and temperature.

Explanation:

Effect of Temperature:

                              Temperature has direct effect on the kinetic energy of water molecules. Greater the Temperature greater is the K.E of molecules and lesser is the intermolecular forces between molecules. Therefore, at temperature below 0 °C water exists in solid state, at temperature in between 0 and 100 °C it exists in liquid state and (at sea level) and above 100 °C it exists in vapor state.

<h3>Answer:</h3>

                 The state of water is determined solely by the conditions of <u>pressure and temperature</u>.

<h3>Explanation:</h3>

Effect of Temperature:

                               Temperature has direct effect on the kinetic energy of water molecules. Greater the Temperature greater is the K.E of molecules and lesser is the intermolecular forces between molecules. Therefore, at temperature below 0 °C water exists in solid state, at temperature in between 0 and 100 °C it exists in liquid state and (at sea level) and above 100 °C it exists in vapor state.

Effect of Pressure:

                              The state of water is also influenced by the external pressure. For example, water can be converted into gas phase by reducing the external pressure (this technique is used in vacuum distillation where solvents are evaporated at temperatures lower than their boiling points) and also, the water can remain in liquid state even above 100 °C if the external pressure is increases (this method is being utilized in daily use pressure cookers).

tekilochka [14]

The given question is incomplete. The complete question is :

In each row check off the boxes that apply to the underlined reactant. The underlined reactant acts as a... (check all that apply)

1. HCH_3CO_2(aq)+NH_3(aq)\rightarrow CH_3COO^-(aq)+NH_4^+(aq)

here underlined is HCH_3CO_2

A. Brønsted-Lowry acid

B. Brønsted-Lowry base

C. Lewis acid

D. Lewis base

2. BH_3(aq)+NH_3(aq)\rightarrow BH_3NH_3(aq)

Here underlined is NH_3

A. Brønsted-Lowry acid

B. Brønsted-Lowry base

C. Lewis acid

D. Lewis base

3. HNO_2(aq)+C_2H_5NH_2(aq)\rightarrow NO_2^-(aq) + C_2H_5NH_3^+(aq)

Here underlined is C_2H_5NH_2

A. Brønsted-Lowry acid

B. Brønsted-Lowry base

C. Lewis acid

D. Lewis base

Answer: 1. Brønsted-Lowry acid

2. Lewis base

3. Brønsted-Lowry base

Explanation:

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

1.  HCH_3CO_2(aq)+NH_3(aq)\rightarrow CH_3CO^{2-}(aq)+NH_4^+aq)

As HCH_3CO_2(aq) is donating a proton , it acts as a bronsted acid.

2. BH_3(aq)+NH_3(aq)\rightarrow BH_3NH_3(aq)

As NH_3 contains a lone pair of electron on nitrogen , it can easily donate electrons to BH_3 and act as lewi base.

3.  HNO_2(aq)+C_2H_5NH_2(aq)\rightarrow NO_2^-(aq) + C_2H_5NH_3^+(aq)

As C_2H_5NH_2(aq) is accepting a proton , it acts as a bronsted base.
