Based on bond type, CaCI2 has the highest melting point.
Answer:
1.30 g
Explanation:
La reacción que toma lugar es:
Primero <u>convertimos 3.28 g de MgO en moles</u>, usando su <em>masa molar</em>:
- 3.28 g ÷ 40.3 g/mol = 0.081 mol MgO
Después <u>convertimos 0.081 moles de MgO en moles de O₂</u>, usando los <em>coeficientes estequiométricos</em>:
- 0.081 mol MgO *
= 0.0407 mol O₂
Finalmente<u> convertimos 0.0407 moles de O₂ en gramos</u>:
- 0.0407 mol O₂ * 32 g/mol = 1.30 g
Answer:
0.504 M
Explanation:
Step 1: Write the balanced neutralization reaction
2 KOH + H₂SO₄ ⇒ K₂SO₄ + 2 H₂O
Step 2: Calculate the reacting moles of KOH
55.2 mL (0.0552 L) of 0.500 M KOH react. The reacting moles of KOH are:
0.0552 L × 0.500 mol/L = 0.0276 mol
Step 3: Calculate the moles of H₂SO₄ that reacted with 0.0276 moles of KOH
The molar ratio of KOH to H₂SO₄ is 2:1. The reacting moles of H₂SO₄ are 1/2 × 0.0276 mol = 0.0138 mol
Step 4: Calculate the concentration of H₂SO₄
0.0138 moles of H₂SO₄ are in 27.4 mL (0.0274 L). The molarity of H₂SO₄ is:
[H₂SO₄] = 0.0138 mol/0.0274 L = 0.504 M
Lithium fluoride is the compound name
B it is an aldose to ketose isomerization
