The pH will start high and decrease, as opposed to starting low in increasing, but the buffer region is still at the beginning and the equivalence point is still in the middle.

<h3>What is weak acid?</h3>

Corrosive strength is the propensity of a corrosive, represented by the synthetic recipe HA, to separate into a proton, H+, and an anion. Powerless acids don't totally separate into their particles in water. For instance, HF separates into the H + and F - particles in water, yet some HF stays in arrangement, so it's anything but a solid corrosive. There are a lot more powerless acids than solid acids. Most natural acids are feeble acids. A feeble corrosive isn't totally ionized in arrangement. For instance, hydrofluoric corrosive, HF, is a feeble corrosive. At the point when broken up in water, HF particle exist in balance with H +, which responds with water to shape hydronium, and F - particles. Since the corrosive doesn't totally separate into its ionic parts, it is a frail corrosive.

The compound ncl3 is nitrogen trichloride, but alcl3 is simply aluminum chloride. why
AveGali [126]
The answer to this question would be:
NCl3 is a molecular compound (two or more nonmetals), and therefore in its name prefixes indicate the number of each type of atom. so NCl3 is nitrogen trichloride<span>.
</span><span>The compound AlCl3 is an ionic compound (metal and nonmetal), and therefore does not require prefixes. so AlCl3 is aluminum chloride.
</span><span>
Both of nitrogen and chlorine is nonmetal, but aluminum is metal. Metal with nonmetal will make an ionic compound that doesn't need prefixes.</span>

Answer:

This is all true if the atom has to be neutral.

Also what does V mean?

Helium: one shell with 2 neutrons and 2 protons in the center, with 2 electrons in the first shell.

Lithium: two shells with 4 neutrons and 3 protons in the center, with 2 electrons in the first shell, and 1 electron in the second shell.

Nitrogen: two shells with 7 neutrons and 7 protons in the center, with 2 electrons in the first shell, and 5 electrons in the second shell.

Flourine: two shells with 9 protons and 10 neutrons in the center, with 2 electrons in the first shell, and 7 electrons in the second shell.

Neon: two shells with 10 neutrons and 10 protons in the center, with 2 electrons in the first shell, and 8 electrons in the second shell.

Boron: two shells with 6 neutrons and 5 protons in the center, with 2 electrons in the first shell, and 3 electrons in the second shell.

How many electrons in an atom can share the quantum numbers n = 2, l = 1?<br> 1<br> 3<br> 6<br> 10
Igoryamba
Principal quantum number is n = 2, principal quantum number gives the energy shells electrons reside in,
angular momentum quantum number , these are the number of subshells and gives how many subshells are there in energy shells, values for l range from 0 to n-1
magnetic quantum number -m- gives the specific orbital in the subshells and their orientation.
spin quantum number gives the spin of the electrons.

in this case, n = 2
the types of subshells in n=2 are 0 and 1
0 - s subshell 
1 - p subshell
the  specific number of orbitals are given by -l to +l
when l = 1
then -1, 0 and +1
therefore there are 3 orbitals in p subshell and orbitals are in 3 orientations
each orbital can hold a maximum of 2 electrons, 
since there are 3 orbitals each holding 6, there are 6 electrons to which these quantum numbers are the same
answer is 6
