I believe it is less dense.. that is why ice floats on water
Answer: salt water is a mixture because it contains 2 substances.
Explanation:
Salt and water are both compounds when added together making it salt water it turns into a mixture
The molar mass of KI is 166 grams per mole.
To solve this we simply use a quick dimensional analysis
We need to cancel everything but Liters so we multiply:
1/2 L/mol x 1/166 g/mol x 500 g = 1.50 L
Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance. Therefore, the work done on the gas (in joules) is 4.95 J.
<h3>
What is Enthalpy?</h3>
Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances.
Mathematically,
q = n ×ΔH
where
q = amount of heat
n = no of moles
ΔH = enthalpy
n = w / M.M
Work in thermodynamic= work done on the system =p×change in temperature
work done on the system= 1.5 atm×(5.1 L - 1.8 L. )
work done on the system=4.95 J
Therefore, the work done on the gas (in joules) is 4.95 J.
