Write the empirical formulas of the following compounds: (a) Al2Br6, (b) Na2S2O4, (c) N2O5, (d) K2Cr2O7, (e)H2C2O4.
babunello [35]

Answer:1. AlBr_3

2. NaSO_2

3.N_2O_5

4. K_2Cr_2O_7

5. HCO_2

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

1. Al_2Br_6 has empirical formula of AlBr_3

2. Na_2S_2O_4 has empirical formula of NaSO_2

3.N_2O_5 has empirical formula of N_2O_5  

4. K_2Cr_2O_7 has empirical formula of K_2Cr_2O_7

5. H_2C_2O_4 has empirical formula of HCO_2

This is known as Rutherford's gold foil experiment. To align with J.J Thompson's Plum Pudding Model, he expects a beam of alpha particles to just pass through the gold foil undisturbed. However, some were deflected at certain angles. Alpha particles are positive, so it would just go straight through the nucleus, but will deflect if it hits the electrons. <em>Therefore, the answer is: </em><span><em>Particles that struck the nucleus went straight.</em></span>
