Agummie bear was tested through a flame-calorimeter test. the bear had a mass of 1.850 grams and the temperature of 100.0 milliliters of water increased by 15.0 degrees celsius. how many calories were in the gummie bear? show all of your calculations.

- 1500 calories

Solution:- mass of bear = 1.850 g

volume of water = 100.0 mL

Density of water is 1.00 g/moL. So, mass of water would be 100.0 g.

delta T for water = 15.0 degree C

specific heat capacity for water is 1 cal/(g* degree C)

q = m x c x delta T

where, q is the heat energy, m is mass, c is specific heat capacity and delta T is change in temperature.

for water, q = 100.0 x 1 x 15.0

q = 1500 calorie

heat gained by water = heat lost by bear

So, the 1.850 g bear has 1500 cal or 1.50 Cal.

(Where, 1 Cal = 1000 cal)

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
