You are about to undertake an experiment to determine the atomic mass of an element that you recently discovered and named Beanium. Research has verified the existence of 3 isotopes of this new element, which are called: LIMA-49, KIDNEY-51, and PINTO-54. Required:
Use the sample provided to determine the % occurrence of each isotope and then calculate the atomic mass of your element.

Describe the chemical reaction based on the chemical equation below. also, explain whether the equation is balanced.

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
