Answer:
I don't know like probably 198km/h
Answer:
Its located on North America
When the solution used begins to change color and stays the new color for at least 30 seconds we are able to tell that the solution has reached the end point of titration
Explanation:
For the given reaction 
Now, expression for half-life of a second order reaction is as follows.
....... (1)
Second half life of this reaction will be
. So, expression for this will be as follows.
=
...(2)
where
is the final concentration that is,
here and
is the initial concentration.
Hence, putting these values into equation (2) formula as follows.
=
=
...... (3)
Now, dividing equation (3) by equation (1) as follows.
=
= 3
or,
= 3
Thus, we can conclude that one would expect the second half-life of this reaction to be three times the first half-life of this reaction.
Answer:
Explanation:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
