It would be lithium and Chlorine because they are trying to get 8 valence electrons and 1 valence electron plus 7 valence electrons.
Answer:
Plasma
Explanation:
Plasma is a state of matter that in some cases is a synonym of ionized gas. It consists of groups of ions (particles with a net charge) with some of their outer electrons removed.
How many electrons have been removed depends on the type of plasma, since the most energetic plasmas are completely free of orbiting electrons. This is the case of the interiors of the sun and other stars.
Explanation:
It is known that specific heat of water is 4.184 and atomic mass of tin is 118.7 g/mol. For the given situation,
Let us assume that,
= mass of Sn
= mass of
Therefore, heat energy expression for heat lost and gained is as follows.
= 0.207
For, 118.7 g the specific heat of tin will be calculated as follows.
= 24.5
Thus, we can conclude that specific heat of tin is 24.5 .
Answer:
(a) The concentration of after 5.00 min is 0.9672 mol/L
(b) The fraction of decomposed after 5.00 min is 0.568
The problem can be solved by using first order integrated reaction.
Explanation:
(a)
Rate constant of reaction = K =
Initial concentration of = 2.24 mol/L
Assuming final concentration of to be x mol/L
time (t) = 5.00 min
The first order integrated equation is shown below
Concentration of decomposed = 0.9672 mol/L
(b)
Concentration of decomposed =
Fraction of decomposed =
