If a non-cyclic alkane shows a molecular ion peak at m/z 3.80 × 102, what is the chemical formula?
soldier1979 [14.2K]
The General Equation of Alkane is as follow,

                                              CnH₂n₊₂          ------- (1)
As m/z = 380
So,
                                              CnH₂n₊₂  =  380
Or,
                                              12n+ 1₂n₊₂  =  380

                                              12n+ ₂n ₊ ₂  =  380

                                              14n ₊ ₂  =  380

                                                   14n  =  380 - 2

                                                   14n  =  378

                                                       n  =  378 / 14

                                                       n  =  27
Now, putting value of n in eq. 1

                                              C₂₇H₍₂₇ₓ₂₎₊₂

                                                  C₂₇H₅₆
Result:
           n  =  C  =  27

           y  =  H  =  56

Why are acids, bases and even some salts commonly used in cleaning applications?
Jet001 [13]

Answer:

Hope this helps :)

Explanation:

In the chemical industry, acids react in neutralization reactions to produce salts. For example, nitric acid reacts with ammonia to produce ammonium nitrate, a fertilizer. Additionally, carboxylic acids can be esterified with alcohols, to produce esters.

Acids are used to remove mineral deposits, rust stains, and hard water deposits. They can remove discoloration from some metals, such as aluminum, brass, bronze, and copper. Some acids are effective both in cleaning and disinfecting surfaces.
