Answer:
Explanation:
HA + H₂O ⇌ H₃O⁺ + A⁻
1. Calculate pKₐ
2. Calculate the pH
We can use the Henderson-Hasselbalch equation to get the pH.
Answer:
<u>because of the process of refraction of light.</u>
Explanation:
Note, the term refraction refers to the process which results in the <em>bending of light </em>as it passes through a medium. This bending of light can make objects become magnified (or larger), or even smaller.
In this scenario, as the light passes slowly through water it affects how we perceive the objects (the words on the paper) behind the jar (more likely a glass jar). In other words, the light combined with the water refracts (changes direction of) the lights our eyes can see, making the letters seem to change size.
Answer:
Light and sound both are waves, but sound requires a material medium to travel, and hence cannot travel in empty space while light can travel through vacuum but not through opaque materials. Both undergo refraction, diffraction and interference.
Explanation:
It is B) H3PO4<span> and HPO</span>4<span>2–
</span>
If the volume of 425 grams was 48.0 cm³, simply divide
g/cm³ = 425 g/48 cm³ = 8.85 g/cm³
If using water in water displacement, 1 mL = 1 cm³
8.85 g/cm³ = 8.85 g/mL
This density is most closely aligned with that of B. Copper
