Answer:
non polar molecules
Explanation:
Ethyl alcohol will dissolve in water in all proportions because the polar molecules interact with each other freely. In contrast, gasoline is a nonpolar molecule. hope that helped...

Answer:
Specific heat of alloy = 0.2 j/ g.°C
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Given data:
Mass of bold = 25 g
Heat absorbed = 250 J
Initial Temperature = 25°C
Final temperature = 78°C
Specific heat of alloy = ?
Solution:
Change in temperature:
ΔT = 78°C - 25°C
ΔT = 53°C
Now we will put the values in formula.
Q = m.c. ΔT
250 j = 25 g × c ×53°C
250 j = 1325 g.°C × c
250 j / 1325 g.°C = c
c = 0.2 j/ g.°C
This is heated until evaporation occurs and sugar crystals are precipitated. This is similar to how chemical sedimentary rocks are formed (like rock salt or cave limestone). It is then separated into small individual crystals. This can be representative of weathering and erosion of rock into sediment
