Answer:
Use the x method, cross over each charge.
Explanation:
and the +1 and -1 cancel each other out, so it will be KBr
I believe the answer is 2
We can get ΔG from this formula:
ΔG = -R*T*(㏑K)
when K = p(N2O4) / p(NO2)^2
we have P(N2O4) = 1.64 atm
and P(NO2)^2 = 0.38 atm
by substitution:
=1.64 atm / (0.38)^2
= 11.36
and R = 8.314
and T = 298 K
so by substitution on ΔG formula:
∴ ΔG = 8.314 *298 *(㏑ 11.36)
= - 6020.7
Answer:
You determine the net force of an object by adding up all of the individual forces.
Explanation:
If N is the number of forces acting on the body, the net force formula is:
= + + ....+
Where , , and as forces acting on a body.
When a body is at rest, the net force formula is given by
Fa = Applied force and
Fg = Gravitational force.
<u>Example:</u>
A truck is standing still and a force of 70 N is applied on it. If the frictional force is 20 N, then what will be the net force?
Solution:
Given
Applied force Fa = 70 N
Frictional force Ff = 20 N
The net force formula is given by
FNet = Fa + Ff
FNet = 70 + (-20)
FNet = 50 N
Therefore, the net force is 50 N
