Water-rich solutions carrying metallic salts fill cracks and form <u>veins</u>.
You want us to answer all that and only get 5 points that’s not fair :(
Answer:
.02232 mole
Explanation:
At STP each 22.4 liters is a mole
.5 liters / 22.4 l/mole = .02232 mole
Answer:
pH = 11.60
Explanation:
When we add a base, we are increasing [OH⁻], so the pH will be totally basic.
pH of water = 7
Basic pH > 7
We are adding 2 M . 1 mL = 2 mmoles
2 mmoles of OH⁻ are contained in 501 mL of total volume.
[OH⁻] = 2 mmol / 501 mL = 3.99×10⁻³ M
- log 3.99×10⁻³ M = 2.39 → pOH
pH = 14 - pOH → 11.61
Water equilibrium
2H₂O ⇄ H₃O⁺ + OH⁻ Kw = 1×10⁻¹⁴
NaOH → Na⁺ + OH⁻
Solids. Low molecular degrees of freedom means the molecules are not free to rotate or move about, and high intermolecular forces means strong bonds form between the molecules. That basically describes a solid.
