The specific heat capacity of silver is 0.233 J/gºC and the specific heat capacity of water is 4.184 J/g°C. A 15.0 gram sample of silver was heated to 85.0°C and put into water in a calorimeter at a temperature of 23.0°C. The final temperature of the system was 25.5°C. What was the mass (in grams) of water in the calorimeter?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.

It idk haha what are we doing?
