Hey there :)
We can see that the solubility of salt increases with increasing temperature. This happens with most substances.
To find out the maximum mass of copper sulfate that can be dissolved in water at these temperatures, just interpret the graph.
Considering Y-axis as g copper sulfate/100 g water and the X-axis as the temperature in °C:-
<u>1)</u>
a: <u>0 °C - 14 g of copper sulfate/100 g of water</u>
b: <u>50 °C - 34 g of copper sulfate/100 g of water</u>
c: <u>90 °C - 66 g of copper sulfate/100 g of </u><u>water</u>
<u>2)</u> From the graph, we can infer that temperature affects the solubility of the salt.

Answer:
Therefore we can say that the total number of electrons present in $ p - $ orbital of chlorine atoms is eleven.
Explanation:
Answer:
It will reach to its maximum volume.
Explanation:
Using Ideal gas equation for same mole of gas as
:-
Given ,
V₁ = 65.0 mL
V₂ = ?
P₁ = 745 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 745 / 760 atm = 0.9803 atm
P₁ = 0.9803 atm
P₂ = 0.066 atm
T₁ = 25 ºC
T₂ = -5 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
T₂ = (-5 + 273.15) K = 268.15 K
Using above equation as:
Solving for V₂ as:-
V₂ = 868 L
Given that:- V max = 835 L
<u>Thus, it will reach to its maximum volume.</u>
Answer:
red car will travel a much farther distance and at a faster speed as opposed to the blue car
Explanation:
Based on the information provided within the question Jenna can expect to observe that the red car will travel a much farther distance and at a faster speed as opposed to the blue car which will travel a shorter distance and at a lower speed. This is mainly because Jenna is applying an increased amount of force on the red car thus creating more acceleration and ultimately increasing the distance.
