Answer:
Conjugate base: Propionate
Explanation:
- Conjugate base contains one less proton as compared to it's parent acid. Deprotonation occurs from most acidic region.
- Propionic acid deprotonates to produce it's strong conjugate base propionate.
- In propionic acid, -OH group in -COOH functional moiety dissociates to produce . Because the O-H bond electrons remains highly polarized towards oxygen atom due to electron withdrawing inductive effect as well as resonating effect of -COOH moiety.
- Structure of conjugate base has been shown below.
Answer:
1.8g/cm³
Explanation:
Density is defined as the ratio of the mass of a substance and the space this subtance occupies. It is usually given in g/cm³.
The mass of the block is 30g.
The volume this mass occupies is 1.5cm × 4.8cm × 2.3cm = 16.56cm³.
The density is:
30g / 16.56cm³ =
<h3>1.8g/cm³</h3>
False .... A neutral atom needs the same number of protons and electrons
PI3, but make sure it is a subscript of 3, not a large number.
