When 50.0 g of 0.200 m nacl(aq) at 24.1 °c is added to 100.0 g of 0.100 m agno3(aq) at 24.1 °c in a calorimeter, the temperature increases to 25.2 °c as agcl(s) forms. assuming the specific heat of the solution and products is 4.20 j/g °c, calculate the approximate amount of heat in joules produced.

Q = 693 J

Explanation:

NaCl (aq) + AgNO₃ (aq) → AgCl (s) + NaNO₃ (aq)

Q = mcΔT

Q: heat

m: mass

c: specific heat

ΔT: temperature variation

Q = (50.0g + 100.0g) x (4.20 J/g°C) x (25.2°C - 24.1°C)

Q = 693 J

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
