Answer:
2,8,8
when Ca gives out 2 electrons it is deducted from it's electronic configuration in it normal state
Answer:
The pH does not increase drastically because the NaOH reacts with the _HYDRAZOIC ACID__ present in the buffer solution.
Explanation:
NaOH reacts with the hydrazoic acid in the buffer
HN3 + OH? --> H2O + N3-
If you put acid in, it will react with N3-. Here is the equation below:
N3- + H+ --> HN3
Answer:
32.4°C
Explanation:
Consider the following expression:
P•V/T =P'•V'/T'
Where P and P' are respectively the initial and the final pressure, V and V's are respectively initial and final volume, and T and T' are respectively initial and final temperature.
We know that the pressure cannot change, so it means that P = P'
We also know that the volume must be increased in 20%, and if we multiply the volume by 1.2 is like increase it in 20%, so we can write that V' = 1.2•V, and changing a little more we can write that V'/V = 1.2
So let's do some maths:
P•V/T = P'•V'/T'
T'•P•V/T = P'•V'
T'•P•V = P'•V'•T
T'=P'•V'•T/P•V
We know that P'=P so the division is equal to 1:
T'= 1•V'•T/V
We also know that V'/V = 1.2, so:
T' = 1.2•T
And we know the value of T, it's 27, so now we just have to solve it:
T' = 1.2•27
T' = 32.4°C
