<h2>
Answer:</h2>
The water has higher specific heat capacity which affects the lakes largely in such way that the water in a lake changes temperature slowly.
<h2>
Explanation:</h2>
Evaporation is a process of liquid changing its state to gaseous state at any temperature. Water has high specific heat due to the presence of strong hydrogen bonds. Due to which it requires heat in huge amount to raise the water (in large quantity) temperature.
Thus, the molecules will be unable to gain much kinetic energy that result in changing the temperature very slowly.

Any mixture that looks the same through the substance is homogenous. The different parts are unable to be visibly seen. (Any periodic element is homogenous)
Any mixture that can be easily determined a mix and cannot be evenly separated or dispersed is heterogenous.
Answer:
70.202 amu
Explanation:
From the question given above, the following data were obtained:
Isotope A:
Abundance (A%) = 39.9%
Mass of A = 69 amu
Isotope B:
Abundance (B%) = 60.1%
Mass of B = 71 amu
Average atomic mass =?
The average atomic mass of the element can be obtained as follow:
Average atomic mass = [(Mass of A × A%)/100] + (Mass of B × B%)/100]
= [(69 × 39.9)/100] + [(71 × 60.1)/100]
= 27.531 + 42.671
= 70.202 amu
Therefore, the average atomic mass of the element is 70.202 amu
The chemical reaction is:
<span>SO2Cl2 </span>⇔<span> SO2+ Cl2
This shows that the forward reaction the compound is decomposed to smaller compounds and the backward reaction the larger compound is produced. Adding more chlorine to the mixture when in equilibrium, will shift the equilibrium to the left forming the larger compound.</span>
Answer is: <span> the equilibrium concentration of Br</span>₂ is 0,02 mol/L.<span>
</span>Chemical reaction: Br₂ + Cl₂ → 2BrCl.
Kc = 7,0.
c₀(Br₂) = 0,25 mol ÷ 3 L.
c₀(Br₂) = 0,083 mol/L.
c₀(Cl₂) = 0,55 mol ÷ 3 L.
c₀(Cl₂) = 0,183 mol/L.
Kc = c(BrCl)² ÷ c(Br₂) · c(Cl₂).
7 = (2x)² ÷ (0,083 mol/L - x) · (0,183 mol/L - x).
7 = 4x² ÷ (0,083 mol/L - x) · (0,183 mol/L - x).
Solve q<span>uadratic equation: x = 0,063 mol/L.
</span>c(Br₂) = 0,083 mol/L - 0,063 mol/L = 0,02 mol/L.
