Answer and Explanation:
A combustion reaction occurs in the presence of oxygen (O2),and it gives carbon dioxide (CO2) and water (H2O) as main products.
So, in each case, we have to write O2 in the reactants side (with the given hydrocarbons), while CO2 and H2O will be in the products side:
a. Butane (C4H10):
![2C_4H_{10}+13O_2\rightarrow8CO_2+10H_2O](https://tex.z-dn.net/?f=2C_4H_%7B10%7D%2B13O_2%5Crightarrow8CO_2%2B10H_2O)
The equation is balanced because in each side of the reaction there are: 8 C, 20 H and 26 O.
b. Cyclohexane (C6H12):
![C_6H_{12}+9O_2\rightarrow6CO_2+6H_2O](https://tex.z-dn.net/?f=C_6H_%7B12%7D%2B9O_2%5Crightarrow6CO_2%2B6H_2O)
The equation is balanced because in each side of the reaction there are: 6 C, 12 H and 18 O.
Answer:
Jonathan’s claim is right.
Explanation:
Jonathan’s claim is right because photons emitted by both sources i.e. sun and the light bulb has the same wavelength which looks practically identical to each other. But some differences in the light spectrum of sun and a light bulb i. e. light bulb has more infrared output than visible and ultraviolet while on the other hand, sun has more visible light than infrared and ultraviolet radiations so we can say that Jonathan's claim is right about the emission of light.
