Okay thanks for reminding me
A graduated cylinder. They are the most common method of getting a required volume of water. (other ways are using volume-metric pipets, graduated pipets, burets, syringes, and volume-metric flask. However these tools are a lot less common)
It is the 3rd option because hydrogen is NOT a metal.
Mass = Density x Volume
Mass = 3.2g/mL x 5 mL
Mass = 16g
Answer:
We are considering an Allene molecule here, CH2CCH2. To answer your question, NO, they don't have to lie on the same plane. The spatial arrangement between them is that the center carbon that forms these pi bind in the left and right are PERPENDICULAR to each other.
Explanation:
We see here that The terminal carbons are sp2 hybridized, and form three σ-bonds each which means that each terminal carbon has one unhybridized p-orbital. The central carbon atom is sp hybridized, and forms two σ-bonds which means it has two unhybridized p-orbitals. For better understanding, let's call these two orbitals px and py. Summarily, These orbitals are perpendicular to each other
