A)
Each mole of Rb₃PO₄ will release:
3 moles of Rb⁺
1 mole of PO₄⁻³
So a total of 4 moles of ions are released per mole.
If there are 0.5 moles, 2 moles of ions will be released.
B)
Each mole of Cr₂(SO₄)₃ will release:
2 moles of Cr⁺³
3 moles of SO₄⁻²
So a total of 5 moles of ions are released per mole.
When there are 0.5 moles, 2.5 moles of ions will be released.

answer is c yes I sure is c
Answer:
Ethane can be converted into 1- butanol in 4 different steps and reactions.
Explanation:
Step 1 : Ethane follows Markovnikov's rule and reacts with a protic acid called Hydrogen chloride to form Chloroethane.
Step 2: Chloroethane undergoes Wurtz reaction where it reacts with sodium metal in the presence of dry ether to form an higher alkane called butane.
Step 3: Butane undergoes chlorination where it reacts with an halogen called chlorine to form 1-chlorobutane.
Step 4: 1-chlorobutane reacts strong aqueous Potassium hydroxide (KOH) to form 1-butanol.
Attached to this answer is the handwritten conversion of Ethane to 1-butanol showing all the reagents and molecules synthesized along the way.
Answer:
Explanation:
<u>1. Number of moles of gasoline</u>
a) Convert 60.0 liters to grams
- mass = 0.77kg/liter × 60.0 liter = 46.2 kg
- 46.2kg × 1,000g/kg = 46,200g
b) Convert 46,200 grams to moles
- molar mass of C₈H₁₈ = 114.2 g/mol
- number of moles = mass in grams / molar mass
- number of moles = 46,200g / (114.2 gmol) = 404.55 mol
<u>2. Number of moles of carbon dioxide, CO₂ produced</u>
a) Balanced chemical equation (given):
- C₈H₁₈ (l) + ²⁵/₂ O₂ (g) → 8 CO₂ (g) + 9 H₂O (g)
b) mole ratio:
- 1 mol C₈H₁₈ / 8 mol CO₂ = 404.55 mol C₈H₁₈ / x
Solve for x:
- x = 404.55mol C₈H₁₈ × 8 mol CO₂ / 1mol C₈H₁₈ = 3,236.4 mol CO₂
<u> 3. Convert the number of moles of carbon dioxide to volume</u>
Use the ideal gas equation:
- R = 0.08206 (mol . liter)/ (K . mol)
Substitute and compute:
- V =3,236.4 mol × 0.08206 (mol . liter) / (K . mol) 298.15K / 1 atm
Round to two significant figures (because the density has two significant figures): 79,000 liters ← answer
Answer: Use the titration formula
