Answer:
The correct option is:
A) by direct or indirect contact between objects at different temperatures
Explanation:
Heat can be transferred in three different methods:
Conduction, Convection and Radiation
Conduction is heat transfer through direct contact between substances at different temperatures.
Convection is the heat transfer which takes place through air currents.
Radiation is the heat transfer that does not require contact between two objects.
Hence, heat transfer can take place through direct or indirect contact between objects at different temperatures.
The problem in this question can be solved using the ideal gas formula. Ideal gas formula show interaction between the pressure, volume, temperature and the number of molecules.
n= number of molecule/ avogadro number
n= (2.0116 x 10^23 / 6.02*10^23)= 1/3 mole
T= celcius + 273.15
T= (41+273.15) K=314.15
P=2280 mmHg / (760mmHg/atm)= 3 atm
PV=nRT
V= nrT/ P
V= 1/3 moles * (<span>0.08205 L atm / mol·K) </span> * 314.15 K / 3 atm
V= 2.864 L
Answer:
Remember that there are 5 moles of water for every 1 mole of hydrate
159.61g mol−1(159.61+5×18.015)g mol−1×100=63.92% CuSO4
This tells you that for every 100 g of copper(II) sulfate pentahydrate, you get 63.92 g of anhydrous copper(II) sulfate. Use this as a conversion factor to get
1.596g CuSO4⋅100 g CuSO4⋅5H2O63.92g CuSO4=2.497 g CuSO4⋅5H2O
Rounded to two sig figs, the answer will be
