Explanation:
Finally something I understand!
densidad es igual de masa/volumen = 150g/25ml = 6g/ml
Hope I got that right
Answer:
If by position, you mean in the Periodic table, and you are looking into the properties of the elements, the answer is "not a whole lot", as these are transition metals.
Explanation:
Unlike the main group elements (columns 1-2 and 13-18) where each column shows a family of elements with a different number of valence electrons, the transition metals differ in the number of d-electrons found in the electron shell that is just below the current valence shell for elements in that row. This causes the transition metals to show only minor variations in properties across a row, and makes attempts at finding similarities between elements in the same column a bit frustrating!
That said, it is true that silver and copper are two of the best metallic conductors of all metals (along with gold), and this can be somewhat attributed to there electron configurations, but you sure aren't looking at something like the halogens here!
Explanation:
We will use the following equation,
(a) Now, we will calculate the value of 
as follows.
= 0.377
As, the 
is 0.21 (which is smaller than the value) this means that equilibrium will shift to the left
.
(b) 
= 0.1155
Here, is smaller than 
which means that the equilibrium will shift to the right.
(c) 
= 0.119
Here, is smaller than which means that the equilibrium will shift to the right
.
(d) 
= 0.21
Since, here the value of comes out to be equal to the given value. Therefore, this reaction is at equilibrium.
(e) 
= 0.36
Here, is higher than the reaction will shift to the left.
Moles of oxygen = mass/molar mass of O2 = 8/31.998 = 0.25 moles.
Number of particles = moles x 6.02 x 10^23 = 0.25 x 6.02 x 10^23 = 1.505 x 10^23 particles.
Hope this helps!
