Answer:
448 J/kg/°C
Explanation:
m₁ C₁ (T₁ − T) + m₂ C₂ (T₂ − T) = 0
(0.0414 kg) C (243°C − 20.4°C) + (0.411 kg) (4186 J/kg/°C) (18°C − 20.4°C) = 0
(9.22 kg°C) C − 4129 J = 0
C = 448 J/kg/°C
True
Explanation:
Nuclear reactions have many useful applications but they also have harmful biological effects. Nuclear reactions are that occurs in the nucleus of an atoms. They differ from chemical reactions which occurs using valence electrons.
Some uses of nuclear reactions:
- They are used for cancer therapy
- Radioactive tracers.
- Production of energy
- Radiometric dating
Some harmful effects:
- Uncontrolled nuclear reactions can lead to nuclear wastes in the environment.
- They are used in manufacturing nuclear weapons.
- They cause destruction of living cells because they produce ionizing radiations.

Answer: The IF clause.
Explanation: This is the IF clause; you can use it as:
IF (something = true) then "something happens"
else "other thing happens"
Some example of it can be, suppose that your program reads a number X that the user inputs, then you can do:
If ( X > 5) then
print: "the number X is bigger than five"
Else
print: "the number X is smaller than five"
Where, of course, the statements depend on the language used, but the "if" clause works almost the same in every language.
Well, since it's C3, we need Tricarbon, and H8 means Octa-, so B is your answer: Tricarbon Octahydride.
Hope this helps~!
