Answer:
4. Atoms in crystals are in an ordered array. In amorphous materials, they are randomly distributed.
Explanation:
Answer:
mass Red Dye 40 = 0.0696 mg
Explanation:
aas found by means of quantitative methods of analysis of dyes in sports drinks:
⇒ [Red Dze 40] = 5.842 E-7 mol/L
analysis performed at a wavelength of 504 nm; value that is below the allowable limits for these drinks.
∴ mass of Red Dye ingested:
⇒ mass Red Dye = (5.842 E-7 mol/L)(496.43 g/mol)(1000 mg/g)(0.240 L)
⇒ mass Red Dye = 0.0696 mg
Answer:
4HCl + SiO2 → 4H2O + SiCl4
axit clohidric Silic dioxit nước Silic tetraclorua
Axit
Explanation:
Hydronium ions are H30+, and pH = -log10[H+]
<span>As H+ ions in solution exist as H3O+ ions, the lower the pH, the higher the concentration of H30+</span>
