Water will freeze at 0°C so the answer is b
Surface of a sphere=4πr²
volume of a sphere=(4/3)πr³
Data:
surface area =432 m²
volume=864 m³
ratio of surface area to volume=surface area / volume
ratio=432 / 864 =0.5
Answer. The ratio would be 0.5
2 HClO(aq) + Ca(OH)2(aq) = 2 H2O(l) + Ca(ClO)2(aq) is the balanced equation
