Answer:

C. 2.

Explanation:

<em>CH₄ + 2O₂ → CO₂ + 2H₂O</em>

  • It is balancing the equation that the number of the atoms is the same in both sides of reactants and products.
  • That we have in both sides; 1.0 C atom, 4.0 H atoms, and 4.0 O atoms.

When 28 grams of a metal are heated from 14.4°C to 150°C it takes 23,200). What is the specific heat of the metal?
suter [353]

Answer:

6.11 J/g°C

Explanation:

We need to use the heat equation: q = mCΔT, where q is the amount of heat required in Joules, m is the mass in grams, C is the heat capacity, and ΔT is the change in temperature.

Here, we know q = 23,200 Joules, m = 28 grams, and the ΔT is just the difference of the temperatures: 150 - 14.4 = 135.6°C. Substitute these values to find C:

q = mCΔT

23,200 = 28 * C * 135.6

C = 6.11

Thus, the specific heat is 6.11 J/g°C.
