A 2.5 g sample of french fries is placed in a calorimeter with 500.0 g of water at an initial temperature of 21°C. After combustion of the french fries the water has a temperature of 48°C. What is the caloric value (kcal/g) of the french fries? The heat capacity, CH2O, of the water is 1.00 cal/g °C. Remember that the heat, q, absorbed be a given mass, m, of water to raise its temperature ❝T degrees is given by q = mCH2O❝T.

5.4 kcal/g

Explanation: heat content of French fries is released to heat the water through a temperature change of 48-21 = 27°c

Heat content h = 500*1*27 = 13500 cal

Calorific value of French fry = 13500/2.5 = 5400 cal/g

= 5.4k cal/g

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
