Among the choices given, the best answer is the third option. Melting ice shows an increase in entropy. Entropy is the degree of disorderliness in a
system. Among the phases, solid has the most ordered structure which means it has the least entropy. The ice melting shows a phase change from solid to liquid. Liquid molecules are more disorganized than the solid thus there is an increase in entropy.
<h3>Answer:</h3>
Density = 1.22 g.mL⁻¹
<h3>Solution:</h3>
Data Given:
Mass = 22.4 g
Volume = 18.3 mL
Density = ??
Formula used;
Density = Mass ÷ Volume
Putting values,
Density = 22.4 g ÷ 18.3 mL
Density = 1.22 g.mL⁻¹
Answer:
The concentrations of the products and reactants do not change
Explanation:
A system is said to be in equilibrium when there is no observable change in concentration of the reactants and products with time.
However, a dynamic equilibrium occurs when the rate of the forward and backward reaction are the same. This implies that the concentration of the reactants and products do not change as long as the physical state of the system is kept constant.
