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)
You may suppose you have a 0.1 M solution of NH3, from:
NH4Cl + NaOH > NH3 + H2O.
Then you can compute the pH from the concentration of NH3 and its pKb.
The concentration is high enough to use the simplified formula:
[OH] = sqr(Kb*conc)
Answer:
D. nuclear fusion because atomic nuclei combine to form a heavier nucleus

Answer:</h3>
A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent.
<h3>
Explanation:</h3>
- A solution is made by dissolving a solute in a solvent.
- For example dissolving a salt in a solvent such as water results to a solution.
- Solution may either be saturated or unsaturated.
- Unsaturated solution is a solution that can dissolve more solute upon addition because it has not reached saturation.
- A saturated solution on the other hand is a solution that has maximum solute and the concentration of solute is maximum and thus the solvent can not dissolve any more solute.
- Therefore, a saturated solutions contain maximum concentration of a solute dissolved in the solute.
Ionization Trend: First ionization energy will increase left to right across a period and increase bottom to top of a family (column).
A) Sr, Be, Mg are all in column 2 of the periodic table. Based on the first ionization rule above, from increasing to decreasing energy, the order is: Be, Mg, Sr
B) Bi, Cs, Ba are all in the same row of the periodic table. Based on the first ionization rule above, from increasing to decreasing energy, the order is: Bi, Ba, Cs
C) Same rule as above. Order is: Na, Al, S
