Answer:
9
option d 9
pH of a 10^-5 M HCI solution is 9
Short answer: 27-13=14 neutrons. Long answer: This is because the atomic number tells you the number of protons and the atomic mass is telling you the overall mass of the atom. The atomic number is important because it distinguishes specific atoms and their locations on the periodic table. Protons have a +1 charge and electrons have a negative charge. On the periodic table, all atoms are neutral this means 0 net charge per atom. That also means protons must equal electrons in a 1:1 ratio because electrons provide a -1 charge. Roughly speaking, protons and neutrons way around 1 amu where electrons weigh a lot less. Why is all this important? It’s important because this should give you an idea as to why you can get the number of neutrons by subtracting the atomic mass by the atomic number.
Noo you need to do get by yourself and look this stuff up in a book idiot
Answer:
Substrate D
Explanation:
In substitution reactions the tertiary substrates cannot undergo substitution via neighboring group participation (NGP) due to the steric impediment, this means that the volume occupied by the substituents is very large and makes it impossible to attack the nucleophile to the substrate carbon.
Answer : The correct option is, solution deviate positively from.
Explanation:
According to the Rouault's law, there are two types of deviation which are negative deviation and positive deviation.
In negative deviation, the A-A interactions and B-B interactions are weaker than the A-B interactions that means A-B interactions are more due hydrogen bonding.
For example : chloroform & acetone form a non-ideal solution. The volume of solution will always be more.
In positive deviation, the A-A interactions and B-B interactions are stronger than the A-B interactions.
For example : acetone & benzene form a non-ideal solution. The volume of solution will always be less.
As per question, the interaction between individual liquids are stronger than the solution of two liquid's interactions. That means, the solution deviate positively from.
Hence, the correct option is, solution deviate positively from.
