In comparison to most other liquids, the heat capacity of liquid water is ________.

Chemistry
1 answer:
makkiz [27]3 years ago
4 0

Answer:

c. higher than other liquids

Explanation:

As many other anomaly in water, heat capacity is  consequence of relatively strong hydrogen bonds. Because of these bond, molecules of water need more energy (than many others liquids) to increase their movement (vibration) and, finaly, to increase temperature of water.

Prepare a journal about the topic Water-The Life Giving Liquid
Alex

Water is known as a life-giving liquid because every living organism depends on the water for its survival.

<h3>Journal about the topic Water-The Life Giving Liquid</h3>

Water is also called a life-giving liquid because without water life on earth is not possible. All other living organisms need to consume water to survive and grow in size. We need water for many other activities such as cleaning, washing, cooking and irrigation. Water is essential for all living things including humans, animals and plants. Water is called wonder liquid as it can dissolve large number of substances. This property enables water to be a great solvent. Most of the chemical reactions of the living world is carried out in water as a medium so that's why water is known as Life Giving Liquid.

So we can conclude that Water is known as a life-giving liquid because every living organism depends on the water for its survival.

A chemist has synthesized two new dyes based on the molecular structure of plant-based dyes. The lowest energy absorption line f
Nimfa-mama [501]

Answer:

1. The dye that absorbs at 530 nm.

Explanation:

The dye will absorb light to promote the transition of an electron from the HOMO to the LUMO orbital.

The higher the gap, the higher the energy of transition. The energy can be calculated by E = hc/λ, in which h and c are constants and λ is the wavelength.

The equation shows that the higher the energy, the higher the gap and the lower the wavelength.

Therefore, the dye with absorption at 530 nm has the higher HOMO-LUMO gap.

A sample of gas initially has a volume of 2.25 L at 350 K and a pressure of 1.75 atm. What will be sample pressure if the volume
IRINA_888 [86]

Answer:

8.44 atm

Explanation:

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

Initial volume (V₁) = 2.25 L

Initial temperature (T₁) = 350 K

Initial pressure (P₁) = 1.75 atm

Final volume (V₂) = 1 L

Final temperature (T₂) = 750 K

Final pressure (P₂) =?

The final pressure of the gas can be obtained as illustrated below:

P₁V₁/T₁ = P₂V₂/T₂

1.75 × 2.25 / 350 = P₂ × 1 / 750

3.9375 / 350 = P₂ / 750

Cross multiply

350 × P₂ = 3.9375 × 750

350 × P₂ = 2953.125

Divide both side by 350

P₂ = 2953.125 / 350

P₂ = 8.44 atm

Thus, the final pressure of the gas is 8.44 atm.

Answer:

5.702 mol K₂SO₄

General Formulas and Concepts:

<u>Atomic Structure</u>

  • Reading a Periodic Table
  • Compounds
  • Moles

<u>Stoichiometry</u>

  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

[Given] 993.6 g K₂SO₄

[Solve] moles K₂SO₄

<u>Step 2: Identify Conversions</u>

[PT] Molar Mass of K: 39.10 g/mol

[PT] Molar Mass of S: 32.07 g/mol

[PT] Molar mass of O: 16.00 g/mol

Molar Mass of K₂SO₄: 2(39.10) + 32.07 + 4(16.00) = 174.27 g/mol

<u>Step 3: Convert</u>

  1. [DA] Set up:                                                                                                       \displaystyle 993.6 \ g \ K_2SO_4(\frac{1 \ mol \ K_2SO_4}{174.27 \ g \ K_2SO_4})
  2. [DA] Divide [Cancel out units]:                                                                         \displaystyle 5.7015 \ mol \ K_2SO_4

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 4 sig figs.</em>

5.7015 mol K₂SO₄ ≈ 5.702 mol K₂SO₄
