1. Imagine doing the same virtual experiment using wood as the bottom material, instead of glass or water. Predict how the light

would interact with the wood.

The wood can't do the same function as done by the water and glass in the same virtual experiment due to its different chemical composition.

The light will not pass through the wood due to its translucent behaviour that prevents light to pass through it as compared to water and glass which are transparent materials and light can easily pass through it.

So using wood as a bottom material instead of glass and water will not perform the same function as perform by water and glass in the same virtual experiment so we can conclude that wood can't perform the same function in the experiment.

A 4.70 g of a C.H. compound was combusted in air to make 15.3 g of CO, and 4.70 g H.O. What is the empirical formula? Balance th
34kurt

Answer:

The empirical formula is C₂H₃

Explanation:

The empirical formula of a chemical compound is defined as the simplest positive integer ratio of atoms present in a compound.

The reaction of combustion for a CₐHₓ is:

CₐHₓ + (a+x/4) O₂ → a CO₂ + ˣ/₂ H₂O

The moles obtained are

15,3 g of CO₂ × \frac{1mol}{44,01g} = 0,3476 moles of CO₂≡moles of C

4,70 g of H₂O × \frac{1mol}{18,02g} = 0,2608 moles of H₂O × 2 = 0,5216 moles of H.

The ratio H:C is 0,5216/0,3476= 1,5. That means you have 1,5 H per 1C, that is the same than 3H per 2C. Thus, empirical formula is:

C₂H₃

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring
iren2701 [21]

Answer:

1.20 V

Explanation:

The standard cell potential is calculated from the expression

ε⁰ cell = ε⁰ oxidation + ε⁰  reduction

The species that will be reduced is the one with the higher standard reduction potential and the species that will be oxidized will be the one with the more negative reduction potential.

Thus for our question we will have

oxidation:

Pb(s)  →   Pb2+(aq) + 2 e-       ε⁰ oxidation       =  -   ε⁰  reduction

                                                                          =   - ( - 0.13 V ) = + 0.13 V

reduction    

Br2(l) + 2 e- → 2 Br-(aq)           ε⁰  reduction     = +1.07 V

ε⁰ cell = ε⁰ oxidation + ε⁰  reduction = + 0.13 V + 1.07 V  = 1.20 V
