Answer:b

Reason

A. They have more energy than a in a solid not less

B. Particles in a liquid are faster than a solid but slow than a gas. They are closer together than a gas but further apart then a solid.

C. Particles in a solid are as slow as they can get.

D. They are closer then in plasma

Answer: Option (b) is the correct answer.

Explanation:

In liquids, molecules are closer together as compared to molecules of a gas. As molecules of a liquid are held by less strong forces of attraction.

Hence, these molecules have some  kinetic energy due to which collisions occur between them.

Since, there are gaps present between molecules of a liquid. Therefore, they have definite volume but no definite shape.

On the other hand, molecules of a gas are held together by weak intermolecular forces. Hence, they have very high kinetic energy and more number of collisions take place between them.

Gases do not have a definite shape and they occupy whole volume of a container in which they are kept.

In solids, molecules are held together by strong intermolecular forces of attraction. Hence, they are not able to move from their initial place and thus they have definite shape and volume.

Therefore, we can conclude that the statement they are closer together and slower moving than the particles in a gas, is generally true about the particles in a liquid.

<u>Chemistry</u>

<u>Stoichiometry</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] 2NaOH (s) + CO₂ (g) → Na₂CO₃ (s) + H₂O (l)

[Given] 1.85 mol NaOH

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

[RxN] 2 mol NaOH → 1 mol H₂O

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol

<u>Step 3: Stoichiometry</u>

  1. Set up:                               \displaystyle 1.85 \ mol \ NaOH(\frac{1 \ mol \ H_2O}{2 \ mol \ NaOH})(\frac{18.02 \ g \ H_2O}{1 \ mol \ H_2O})
  2. Multiply/Divide:                 \displaystyle 16.6685 \ g \ H_2O

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

16.6685 g H₂O ≈ 16.7 g H₂O

state the conditions under which copper reacts with sulphuric (vi) acid and give an equation for the reaction​
uranmaximum [27]

Answer:

When the metal reacts with hot, concentrated sulphuric acid, the products of the reaction are copper (II) sulphate, sulphur dioxide and water. Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O. This is a typical redox reaction in which the acid is reduced to SO2, but no hydrogen is produced here
