The food calorie (also known as nutritional calorie and large calorie) is a quantity equal to a kilocalorie (kcal). not surprisingly, the food calorie is used to represent units of energy associated with eating, as in “an average hot dog with ketchup and a bun contains 315 calories.” you woke up hungry this morning so you ate a breakfast of hotcakes, eggs, and a large biscuit. an online application indicates that this meal contains 1090 calories (meaning food calories).how many stairs (of height 7.25 inches) would a person of mass 180.0 lb, have to climb in order to expend the calories consumed in your breakfast?

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

the entire statement is true and correct.
