Answer:
27.0
Explanation:
Because Mass can neither be created nor be destroyed hence total mass of sample of iodine and tube remain equal as it is sealed.
Mechanical Energy has to do with the motion and position of objects; It is also deemed the sum of Kinetic and Potential Energy. Thus the most suitable answer for the energies associated with mechanical energy is 'KINETIC ENERGY and POTENTIAL ENERGY.'
Answer: V = 6.30L
PV = nRT
15°C = 15+273 = 288K
3.75*V = 1.50*0.082057*288
V = (1.50*0.082057*288)/3.75
V = 6.30L

B. No since rusting is a chemical change it does not follow the law of conservation of mass.
Please, you have to apply the formula below:<span>Q=c∗m∗Δt</span>where Q is the energy lost, c is the specific heat of water, m is the mass of water involved, so m=3.75 *10^-1 Kg c=4,184 J/(Kg*°C) delta t=37.5 °C
Taking density of water as 1000kg/m3. Mass of water would be 0.375kg. So, heat lost would be<span>H=mCDeltaT</span>H=0.375*4184*37.5 = 58837.5J
