The average rate from 2.0 to 6.0 seconds in mol/L is 0.004025 mol/L.
<h3>What is decomposition reaction ?</h3>
Decomposition reactions are those in which a reactant undergoes reaction to form two or more products.
2AX2(g) -------> 2AX(g) + X2(g)
t1 = 2.0 s and t2 = 6.0 s
x1 = 0.0249 and x2 = 0.0088
Average rate of reaction:
Ra = ∆[x]/DeltaT = X2 - X1/t2 - t1
Ra = 0.0088 - 0.0249/6 - 2 = 0.004025 mol
Thus, the average rate is 0.004025 mol/L.

Answer:
y = 1.75 cm
Explanation:
In the double-slit experiment the equation for destructive interference is
d sin tea = (m + ½)
λ
let's use trigonometry to find the angle
tan θ = y / L
as all the experiment does not occur at small angles
tan θ = sin θ / cos θ = sin θ = y / L
we substitute
y = (m + 1/2 ) λ L / d
we calculate
y = (3 + ½) 500 10⁻⁹ 5.00 / 0.5 10⁻³
y = 1.75 10⁻² m
y = 1.75 cm

Answer:
D wavelength
Explanation:
The different wavelengths determine the color.
6 chairs will fit across the platform.
<h3>Calculation</h3>
We have a school stage of 8 3/4 feet wide.
It's also given that each chair is 1 5/12 feet wide.
To find out the number of chairs possible we can simply divide the total length available by width of the chair.
8 3/4 = 35/4
1 5/12 =17/12
So, 35/4 / 17/12
So, the final answer comes up to 6.
so, the total number of chairs that would fit in are 6.
