Answer:
Common combustion reactions break the bonds of hydrocarbon molecules,

Answer:
The answer to your question is: 7
Explanation:
The reaction between HCl and NaOH is a neutralization reaction, that means that the products will be water and a salt and the pH will be 7.
HCl + NaOH ⇒ NaCl + H₂O
Lambda = h\ Mv
lambda = 6.624 x 10^-34 / 9.1 x 10^-31 x 2.5 x 10^7
lambda = 2.9 x 10^-11 is your wavelength
