1. A 10 g gold coin is heated from 25°C to 50°C (CAu is 0.13 J/g-°C). What is the H?
Oksanka [162]
The correct answer is + 32.5 J because heat is absorbed here by copper not evolved also after calculation we will find the H value is positive, lets calculate it:
H = m C Δt where:
m = 10 g 
C = 0.13 J/g.°C
Δ t = final temperature - initial temperature = 50 - 25 = + 25 °C
so H = 10 x 0.13 x (+25) = + 32.5 J

Which of the following changes can be reversed by changing the temperature: (a) dew condensing on a leaf; (b) an egg turning har
oksano4ka [1.4K]

Answer:

(a) dew condensing on a leaf

(c) ice cream melting

Explanation:

The process which can be reversed by changing the temperature , i.e. , by increasing or decreasing the temperature , is called the <u>reversible process</u> .

From the question ,  

  • dew condensing on a leaf is a reversible process ,  

As the water on the leaf can be changed to gaseous state by increasing the temperature .  

The process of condensation and evaporation are reversible of each other .

  • Ice cream melting

The melted ice cream can be solidified again by reducing its temperature , hence , it is a reversible process .

  • an egg turning hard when boiled and the batter cooking on a hot griddle

They both are irreversible process , and by changing the temperature , we can not get back the original substance .

Explanation:

molality is the concentration of a solution in moles of solute per kilogram of solvent

moles of solute (NaOH) = 2moles

mass of solvent in kg. =10kg

Therefore molality. = 2moles/10 kg

=0.2mol/kg
