Answer:
20 hydrogen atoms
Explanation:
Let us carefully observe the words of the question. We were told that the compound is a hydrocarbon. This implies that it is composed of only hydrogen and carbon.
Secondly, we are informed that the compounds is composed of only C-C single covalent bonds. This means that the compound is an alkane.
Then we are told that it contains nine carbon atoms and is a linear molecule. Hence, the compound must be n-nonane.
Recall that for alkanes, the general molecular formula is CnH2n+2 Substituting n=9 for nonane we have; C9H(2*9)+2 which is C9H20.
Thus there are 20 hydrogen atoms. The structure of the compound is attached to this answer
Each chemical reaction, you may say that there are many possible balanced reactions since the coefficients of the reactants and of the products can be another set of numbers as long as the ratios of the compounds would be the same. The most preferred balanced reaction would be the reaction which have the lowest value of coefficients. Example would be the reaction of HCl and NaOH.
HCl + NaOH = NaCl + H2O (This would be the most preferred one since the coefficients are in the lowest value)
Other equivalents would be:
2HCl + 2NaOH = 2NaCl + 2H2O
3HCl + 3NaOH = 3NaCl + 3H2O
4HCl + 4NaOH = 4NaCl + 4H2O

Answer:
When aqueous solutions of silver(I) acetate and manganese(II) iodide are combined, an insoluble precipitate of silver(I) iodide is formed
Explanation:
- It is an example of precipitation reaction.
- When aqueous solutions of silver(I) acetate and manganese(II) iodide are combined, an insoluble precipitate of silver(I) iodide is formed.
- Precipitation of silver(I) iodide is confirmed by it's yellow color.
- Hence a reaction is observed.
- Molecular reaction:
