Answer:
Density = 11.4 g/cm³
Explanation:
Given data:
Density of lead = ?
Height of lead bar = 0.500 cm
Width of lead bar = 1.55 cm
Length of lead bar = 25.00 cm
Mass of lead bar = 220.9 g
Solution:
Density = mass/ volume
Volume of bar = length × width × height
Volume of bar = 25.00 cm × 1.55 cm × 0.500 cm
Volume of bar = 19.4 cm³
Density of bar:
Density = 220.9 g/ 19.4 cm³
Density = 11.4 g/cm³

Answer: <span>A geometric isomer with two alkyl groups on the same side of the carbon-carbon double bond is called
<em>cis</em> Isomer.
Explanation: Geometric isomerism takes place about the double bond in alkenes when the alkyl groups are either situated at the same side (<em>
cis</em>) or are situated opposite (
<em>trans</em>) to each other.
Example: <em>
cis</em>
-2-Butene (highlighted red)
<em>
trans</em>
-2-Butene (highlighted blue)</span>
