How much heat is generated when 2.04 g of lead changes in temperature from 104 kelvin to 204 kelvin? report your answer in joules.

When 2.04g of lead is heat from 104 Kelvin to 204 Kelvin, there is 26.112 Joule generated.

Explanation:

Step 1: Data given

2.04 grams of lead changes from 104 to 204 Kelvin

Step 2:  Calculate the generated heat

Q = m*c*ΔT

with Q = Heat energy (in Joules)

with m = mass of a substance (kg)

with c = specific heat (in J/g*K)

with ΔT = Change in temperature = T2 - T1

In this case we have

Q = TO BE DETERMINED

m = 2.04 grams

c = specific heat of lead = 0.128J/ g*K  

ΔT = 204 Kelvin - 104 Kelvin = 100

Q = 2.04g * 0.128 J/g*K * 100 K = 26.112 J

When 2.04g of lead is heat from 104 Kelvin to 204 Kelvin, there is 26.112 Joule generated.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
