Answer:in a mass spectrum of BrCl four (4) peaks will be present
Explanation:
Cl and Br both have two naturally occuring isotopes.Br has 79Br which has abundance50.69% and 81Br which has abundance 49.31%.Similarly two isotopes of Cl are 35Cl having abundance 75.77% and 37Cl having abundance 24.23%.Chlorine and bromine combine and form bromine monochloride .Now they can combine with each other in four possible combinations wich are 1(81Br37Cl) 2(81Br35Cl) 3(79Br37Cl) 4(79Br35Cl) .So these four combined isotopes will show four peaks in mass spectrum.

Answer:
1,100,160J or 262.94 kcal
Explanation:
The juice is frozen at 0 degrees Celsius and I assume that it will become gas at 100 degrees Celsius. So we change the form of the water from solid to liquid, then to gas. That means we have to find out how much heat needed to change water form too, not only the heat needed to increase its temperature.
The latent heat of water is 4.2J/g °C while the heat of fusion is 334 J/g and the heat of vaporization is 2260 J/g. The energy needed will be:
360g * 4.2J/g °C * (110-0°C ) + 360g * 334 J/g + 360g * 2260 /g = 1,100,160J or 262.94 kcal.
