Butene is an alkene, which is a hydrocarbon that contains a double bond. At room temperature, butene occurs as a gas. So, when it reacts with oxygen gas, it will yield gaseous products, carbon dioxide and water vapor. The complete balance reaction is written below:
C₄H₈ (g) + 6 O₂ (g) → 4 CO₂ (g) + 4 H₂O (g)
The movement of material due to differences in density that are caused by differences on temperature is called convection
Answer:
Electronegativity (χ) is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself. Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
Answer:
[Z] = 0.00248M
Explanation:
Based in the reaction:
2A(aq) + B(aq) ⇄ 2Z (aq)
K of the reaction is defined as:
K = [Z]² / [A]²[B] = 0.43
If you add, in the first, just 0.033M of Z, concentrations in equilibrium are:
[Z] = 0.033M - 2X
[A] = 2X
[B] = X
Replacing in K equation:
0.43 = [0.033M - 2X]² / [2X]² [X]
0.43 = [0.033M - 2X]² / [2X]² [X]
0.43 = 4X² -0.132X + 0.001089 / 4X³
<em>1.72X³ - 4X² + 0.132X - 0.001089 = 0</em>
Solving for X:
X = 0.01526M
Replacing, concentration in equilibrium of Z is:
[Z] = 0.033M - 2*0.01526M = <em>0.00248M</em>
