I think the correct answer would be hydrogenous sediment. These sediments are produced when minerals that are dissolved solidify via reaction with water, especially seawater. Other examples are evaporites and oolites. Hope this answers the question.
Answer:
The pressure is 16, 9 atm
Explanation:
We use the formula PV=nRT. The temperature in Kelvis is: 273 + 25 = 298K
PV=nRT P =(nRT)/V
P= (0, 450 mol x 0,082 l atm/K mol x 298)/0,650 l= 16, 91723077atm
The moles of oxygen required to burn Butane is 6 moles.
<h3>What is a Combustion Reaction?</h3>
A reaction in which fuel gets oxidised by an oxidising agent producing a large amount of heat is called a combustion reaction.
In this question
Butane is burnt with oxygen
Molar mass of C₄H₁₀ = (12.0×4 + 1.0×10) g/mol = 58.0 g/mol
Molar mass of O₂ = 16.0×2 g/mol = 32.0 g/mol
Balanced equation for the reaction:
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
Mole ratio C₄H₁₀ : O₂ = 2 : 13
The given mass = 54grams
moles = 54/58 = 0.93 moles
The mole of oxygen required =
0.93/ x = 2/13
0.93*13/2 = x
x = 6.045 moles
Therefore 6 moles of oxygen are required to burn Butane.
