Answer:
Warmth (in addition to sunlight) at the Earth's surface.
Explanation:
Heat radiated from Earth's surface is absorbed by water vapor molecules in the lower atmosphere. The water vapor molecules, in turn, radiate heat in all directions. Some of the heat returns to the Earth's surface. Thus, water vapor is a second source of warmth (in addition to sunlight) at the Earth's surface.
Answer:
At ; 95.0% of the molecules will dissociate at this temperature
Explanation:
The chemical reaction of this dissociation is:
The ICE table is as follows:
Initial 100 0
Change -83 +166
Equilibrium 17 166
The mole fractions of each constituent is now calculated as:
= 0.9071
= 0.0929
Given that the total pressure = 1.000 atm ; the partial pressure of each gas is calculated by using Raoult's Law.
Now; we proceed to determine the equilibrium constant ; which is illustrated as:
Let assume that the partial pressure of be x ;&
the change in pressure of be y ; then
we can write that the following as the changes in concentration of species :
Initial x 0
Change -y +2 y
Equilibrium x - y 2 y
From above; we can rewrite our equilibrium constant as:
From the question; we are told that provided that 95% of the molecules dissociate at this temperature. Therefore, we have:
% -------- equation (2)
Solving and equating equation 1 and 2 ;
x = 0.123 atm
y = 0.117 atm
Thus, the pressure required can be calculated as :
When I think of science, I think of factual evidence from the use of experimentation.
Science is hypothesizing research in order to confirm if the experimentations are true or not.
Explanation:
Net ionic between HCl and the buffer equation
CH3COOH --> acetic acid, CH3COO- acetate , H+ proton from HCl
there is neutralization of the acetate, and an increase in acid
the ionic equation
CH3COO-(aq) + H+(aq) + Cl-(aq) --> CH3COOH(aq) + Cl-(aq)
Net ionic:
CH3COO-(aq) + H+(aq) --> CH3COOH(aq).
