False
becuase the temperates is dependant on heat or cold sources
True.
without natural selection darwin’s theory would not make sense :))
–3568.0 kJ/mol * 1.411 g / 115.27 g/mol = -43.67 kJ<span>
</span>Heat capacity of the calorimeter: -43.67 kJ / 3.379 ° = <span>-12.92 kJ/deg C

Not 100% sure about my answer
Answer:
The answer to your question is E = 419.435 J
Explanation:
Data
Mass = m = 2.004 g
Temperature 1 = T1 = 89°C
Temperature 2 = T2 = 139°C
Specific heat of water = Cp = 4.186 J/g°C
Energy = E = ?
Formula
E = mCp(T2 - T1)
Substitution
E = (2.004)(4.186)(139 - 89)
Simplification and result
E = 8.3887(50)
E = 419.435 J
Answer: 25 moles of product are formed.
Explanation:
The balanced chemical equation will be :
According to stoichiometry :
1 mole of 
require = 3 moles of 
Thus 5 moles of 
will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 4 moles of reactant give = 5 moles of product
Thus 20 moles of reactants will give =
of products
