The oxygen atom has a partial negative charge and the Hydrogen atoms have a partial positive charge
Multiply the number of each element by its mass on the periodic table.
Add them together.
Put the mass of carbon only over the total mass and multiply the result by 100 to get the percentage.
I think that answer would be caves
C. They are composed of the same type of atoms.
Answer:
14.32g
Explanation:
Initial temperature = 83.8°C
Final temperature = 77.1°C
Temperature change, ΔT = 83.8°C - 77.1°C = 6.7
Heat, H = 167J
Specific heat, c = 1.740J/g °C
m = ?
All these parameters are related with the equation below;
H = mcΔT
m = H / cΔT
m = 167 / (1.740 * 6.7)
m = 167 / 11.658 = 14.32g
