What type of reaction is shown below? C5H12() + 502(g) → 5CO2(g) + 6H2(g)
A. Combustion
B. Precipitation
C. Neutralization
D. Decomposition

A. Combustion.

Explanation:

Hello there!

In this case, according to the given information about the shown chemical reaction, whereby liquid pentane reacts with oxygen to produce carbon dioxide and hydrogen (should be water); we can use the attached file to realize this is a A. Combustion reaction as it has CO2 and H2O on the products side from a hydrocarbon fuel.

Regards!

chemistry sucks a**

explanation:

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
