Answer:
A) 0.801
Explanation:
The reaction that takes place is:
- 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
First we c<u>alculate the H₂SO₄ moles that reacted</u>:
- 0.355 M * 28.2 mL = 10.011 mmol H₂SO₄
Now we <u>convert H₂SO₄ moles to NaOH moles</u>:
- 10.011 mmol H₂SO₄ *
= 20.022 mmol NaOH
Finally we <u>calculate the molarity of the NaOH solution</u>:
- 20.022 mmol NaOH / 25.0 mL = 0.801 M
So the answer is option A.
When ice forms, the molecules are farther apart than in liquid water, allowing the ice to form an organized crystal structure and float.
Answer:
Carbon
Explanation:
Carbon is the most important element to life. Without this element, life as we know it would not exist. As you will see, carbon is the central element in compounds necessary for life.
Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
