2H2O2 ------> 2H2O +O2

because we're given one side with 2 hydrogens and 2 oxygens and another sie with 3 oxygens and 2 hydrogens. The hydrogens are balanced but the oxygens are not. You can't make the oxygen a three on the reactants side with a whole number so you multiply by 2.

Now you have 4 hydrogens and 4 oxygens on one side and 4 hydrogens and 4 oxygens on the other :)

Answer:

The minimum thickness of the Lucite plate is 0.670 μm.

Explanation:

Given that,

Wavelength = 650.0 nm

Index of refraction = 1.485

We need to calculate the minimum thickness of the Lucite plate

Using formula of thickness

$t(n-1)=\dfrac{\lambda}{2}$

$t=\dfrac{\lambda}{2(n-1)}$

Where, n = Index of refraction

$\lambda$ = wavelength

Put the value into the formula

$t=\dfrac{650.0\times10^{-9}}{2(1.485-1)}$

$t =0.670\ \mu m$

Hence, The minimum thickness of the Lucite plate is 0.670 μm.
