One mole of carbon (12.0 g) in the form of crystalline graphite is burned at 25◦C and 1.000 atm pressure to form CO2(g). All of

the heat produced is used to heat a 5100 g bath of liquid water, originally at 25◦C. What is the final temperature of the water bath? The heat of formation of CO2(g) is −393.5 kJ/mol and the specific heat of water is 4.18 J/g/◦C. Answer in units of ◦C

Answer:

T₂ = 43.46 °C  

Explanation:

Given that:

The heat of the formation of carbon dioxide = - 393.5 kJ/mol (Negative sign suggests heat loss)

It means that energy released when 1 mole of carbon undergoes combustion = 393.5 kJ = 393500 J

Heat gain by water = Heat lost by the reaction

Thus,    

m_{water}\times C_{water}\times \Delta T=Q

For water:  

Mass of water  = 5100 g

Specific heat of water = 4.18 J/g°C  

T₁ = 25 °C  

T₂ = ?

Q = 393500 J

So,

5100\times 4.18\times (T_2-25)=393500  

T₂ = 43.46 °C

Answer:

The second option

Explanation:

Speed is defined at the rate at which distance changes with time. It is scalar quantity and it is expressed as shown below:

              Speed = \frac{distance}{time}

At constant speed the rate of change of distance with time is the same. On the second graph, this is noticeable. Both distance and time change at the same rate.

BARSIC [14]
The radioactive decay of unstable isotopes continually generates new energy within Earth's crust and mantle, providing the primary source of the heat that drives mantle convection. Plate tectonics can be viewed as the surface expression of mantle convection.

Vocabulary for Decanting
Aleksandr-060686 [28]

Answer:

Decant means "to pour." Kids moving water back and forth between two cups, your dad pouring a bucket of soapy water in the sink, or a wine expert emptying a bottle of wine into a fancy glass container — all of them are decanting liquids.
