4.60 g of of H₂O form when all the butane burns.
<h3>What is butane ?</h3>
One of the smallest liquid streams frequently created in a refinery is butane. Ten hydrogen atoms and four carbon atoms make up the butane molecule. Typically, butane is either marketed as a finished product or is blended into LPG or gasoline in tiny quantities.
It is frequently employed as a fuel for portable stoves and cigarette lighters, as a propellant in aerosols, as a heating fuel, as a refrigerant, and in the production of a broad variety of goods. Liquefied petroleum gas and butane both exist (LPG).
Butane has a low level of toxicity. In butane misuse, high exposure concentrations can be anticipated. Central nervous system (CNS) and cardiac consequences are the most frequently seen effects in cases of misuse.

Answer:
E = 3.825×10⁻¹⁹ J
Explanation:
Wavelength of photon = 5.2 ×10⁻⁷m
Energy of photon = ?
Solution:
Formula:
E = hc/λ
h = plancks constant = 6.63×10⁻³⁴ Js
c = speed of wave = 3×10⁸ m/s
by putting values,
E = 6.63×10⁻³⁴ Js ×3×10⁸ m/s / 5.2 ×10⁻⁷m
E = 19.89×10⁻²⁶ J.m / 5.2 ×10⁻⁷m
E = 3.825×10⁻¹⁹ J
