Answer
Q=4479.8 cal
Procedure
To solve the problem you will need to use the specific heat formula
Where;
Q=heat energy
m=mass
c=specific heat capacity
ΔT=change in temperature
Assuming that the heat released from the cracker of unknown material is equal to the heat absorbed by the water, then we can use the c and m for water in our calculations.
Substituting the values in our equation we have
Finally, transform the J to cal

<em><u>The statement “the scientific process is open ended” means: Would an element with 7 valence electrons be more or less reactive than an element with 3 valence electrons? Element 1 is a hard dark-red solid</u></em>
Isotopes have the same atomic number or same number Protons, but different mass number or neutrons.
You can say atomic number or protons.
22 neutrons 20 protons
atomic number 20 and a mass number 40
Atomic number 20 and mass # 42
