A10.0 gram sample of silver is heated to 100.0 degree c and then added to 20.0 g of water at 23.0 c, in an insulated container. at thermal equilibrium, the temperature of the system was measured and found to be 25.0 c. what is the specific heat, cs, of silver?

Explanation:

Considering that:-

Heat gain by water = Heat lost by Silver

Thus,  

Where, negative sign signifies heat loss

Or,  

For water:

Mass = 20.0 g

Initial temperature = 23.0 °C

Final temperature = 25.0 °C

Specific heat of water = 4.184 J/g°C

For Silver:

Mass = 10.0 g

Initial temperature = 100.0 °C

Final temperature = 25.0 °C

Specific heat of silver = ?

So,  

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
