How much energy would it take to heat a section of the copper tubing that weighs about 535.0 g , from 15.29 ∘C to 21.30 ∘C ? Copper has a specific heat of 0.3850 (J/g)⋅∘C.

1238 J

Explanation:

Step 1: Given data

Step 2: Calculate the change in the temperature

We will use the following expression.

ΔT = 21.30°C - 15.29°C = 6.01°C

Step 3: Calculate the energy required to heat the temperature of the copper tubing (Q)

We will use the following expression.

Q = c × m × ΔT

Q = 0.3850 J/g.°C × 535.0 g × 6.01°C

Q = 1238 J

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

i think so it’s will be b yes i believe its
