The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.
The mass of 40 mL of water is 40 grams. Since D = m/v and mL = cm3, the density of water is 1 g/cm3. Choose a volume between 1 and 100 mL. Use your graph to find the mass.
Different explanations that lead to the same result
-You need to substract the number of protons from the mass number.
-Mass number - atomic number= number of protons
-Following this equation:
CARBON
atomic number= 6
mass number= 12
mass number= protons + neutrons
12= 6 + x
x= 12-6
x= 6
Density, I am pretty sure this is the correct answer.
