Answer:- Atomic number for sulfur is 16 and it's electron configuration is
. Here, there are total for electrons in 3p and the set of quantum numbers for these 4 electrons would be as..
For the first electron of 3p-
n = 3, l = 1, ml = -1 and ms = +(1/2)
for the second electron of 3p-
n = 3, l = 1, ml = 0 and ms = +(1/2)
for the third electron of 3p-
n = 3, l = 1, ml = +1 and ms = +(1/2)
and for the fourth electron of 3p-
n = 3, l = 1, ml = -1 and ms = -(1/2)
Answer:
<h2>15 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

But from the question
volume = final volume of water - initial volume of water
volume = 165 - 150 = 15 mL
We have

We have the final answer as
<h3>15 g/mL</h3>
Hope this helps you
<u>Answer:</u>
<em>The situation given here is imaginary such that the life of Rock has to be found using the half-life of the element lokium that has been found inside the rock. </em>
<u>Explanation:</u>
Half-life of any material is the amount of time taken by that particular material to decay. Now the amount of lokium found in rock can show after how many half-lives this amount has been left out.
The time elapsed will be log (L) atoms X half-life.
Answer:
The ratio of the mass ratio of S to O; in SO, to the mass ratio of S to O; in SO₂, is 2:1
Explanation:
According to the consideration, let us first find the ratio of S and O in both the compounds
For SO:
Let us express it as

For SO₂,
Due to two oxygen atoms in the molecule, the mass of oxygen will be taken two times

Let us express it as

Now, for the ratio of both the above-calculated ratios,

The required ratio is 2:1
