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:
the time taken for crossing the boat is 18.67 seconds
Explanation:
The computation of the time taken for crossing the boat is shown below:
But before that we do the following calculations
=
= √12.25 - √1.21
= √11.04
= 3.32
Now the time taken for crossing the boat is
= 62 ÷ 3.32
= 18.67 seconds
Hence, the time taken for crossing the boat is 18.67 seconds
And, the same is to be considered
Answer:
In summary, it is safe to handle this voltage with dry hands because the current value that you pass through the body is smaller than its underestimated sensitivity.
Explanation:
The current flowing through your system is described by Ohm's law
V = I R
where I is the current, V the voltage and R the resistance
in this case three barateras are taken in series giving a total voltage of V = 4.5 V the typical resistance values of dry skin is R = 1000 000Ohm and the resinification of wet skin is R = 100000 ohm
let's calculate the current flowing
I = V / R
I = 4.5 / 1000000
I = 4.5 10⁻⁶ A
this is the current with dry hands, we see that much less than the value that allows to feel a painful response by the body
If the skin is
I = 4,5 / 100,000
I = 4.5 10⁻⁵ A
This value is small, but it is close to the pain threshold, but it is in the range of slight discomfort.
In summary, it is safe to handle this voltage with dry hands because the current value that you pass through the body is smaller than its underestimated sensitivity.
Answer: Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
