Add barium chloride. Reaction equation as shown:

Li2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2LiCl(aq)

Reaction will result in a white precipitate, making the solution look milky.

Crank

Answer:

Explanation:

Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (all atoms with six protons are carbon atoms), the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.

I hope I helped you!

miv72 [106K]

Answer:

m_{C_6H_5Cl}=65.7gC_6H_5Cl

Explanation:

Hello!

In this case, according to the given balanced chemical reaction:

C_6H_6 (l) + Cl_2 (g) \rightarrow C_6H_5Cl (s) + HCl (g)

We can see there is 1:1 between benzene and chlorobenzene as the relavant product; thus, since the molar mass of benzene is 78.11 g/mol and that of chlorobenzene is 112.55 g/mol, the theoretical yield for this reaction turns out:

m_{C_6H_5Cl}=45.6gC_6H_6*\frac{1molC_6H_6}{78.11gC_6H_6 }*\frac{1molC_6H_5Cl}{1molC_6H_6}*\frac{112.55gC_6H_5Cl}{1molC_6H_5Cl}   \\\\m_{C_6H_5Cl}=65.7gC_6H_5Cl

Best regards!

(I seriously don't understand what this questin means, please don't delete need all the help i can get)

I've always been told that it's eight. This is only because the atom has to have the saem protons (positively charged) neutrons and electrons (negatively charged). However this does not occur with all atoms. :)
