Answer:
80 hours. 2,000 ÷ 25 = 80
Covalent, as Isopentene (2 methylbutane) is completely non-metallic
Soluble means it can be dissolved
Insoluble means it can't be dissolved
Answer : The molecular geometry of is trigonal pyramidal.
Explanation :
Formula used :
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
The given molecule is,
Number of bond pair = 3
Number of lone pair = 1
The total number of electron pair are 4 that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral.
But as there are 3 atoms around the central oxygen atom, the fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be trigonal pyramidal.
Hence, the molecular geometry of is trigonal pyramidal.
Answer:
B
Explanation:
When a phospholipid is found in a sphere of water, the hydrophilic head is expected to point towards the water while the hydrophobic tail will point away from the water.
The term hydrophilic means water loving, So it is expected that the hydrophilic head will move towards water molecules at it has affinity for water molecules.
The opposite is the case for the hydrophobic tail. The hydrophobic tail moves away from water molecules
What these cases suggest is that both regions are acting base on their chemical make up. While the hydrophilic head contains molecules which are capable of interacting and bonding with water molecules, the hydrophobic tail contains strictly non polar molecules which are not capable of water interaction. Hence the interactions a phospholipid has with water is through its head region
