Answer:
To balance a reaction, the amount of reactants must be equal to the amount of products, as stated by the Law of Conservation of Matter. It may help you to keep track of the number of each element in a list as you try to balance. It's not able to be balanced.
Answer:
The change in temperature of a coffee cup calorimeter is 8.87°C.
Explanation:
Volume of the water = V = 150 g
Density of the water , d =1.0 g/mL
Mass of the water = M

Mass of solution = m = M = 150.0 g

Moles of NaOH = 
Energy released when 0.125 moles of NaOH added in water = Q

1 kJ = 1000 J
Heat gained by water = Q' = -Q ( conservation of energy)

Specific heat of solution = c = 4.184 J/g°C
Change in temperature of the solution = 



The change in temperature of a coffee cup calorimeter is 8.87°C.
This is called the Mass Number of the isotope of the atom.
Isotopes are different forms of the same atom. They have the same number of protons but different number of neutrons.
Carbon-12 has mass number 12 as it has 6 protons and 6 neutrons.
Carbon-14 has mass number 14 as its has 6 protons and 8 neutrons.
