The correct answer is B. a fossilized fish
That is because the scientist can use carbon dating to find the age of the fish, and that will tell the scientest the date of the layer of rock. :)
First, you have to know what reacts with Aluminum Nitrate so that you can balance the equation and find out the stoichiometric coefficient. I found a similar question from another website as shown in the picture attached. Balancing the reaction would result to:
2Al(NO₃)₃ + 3FeCl₂ --> 3Fe(NO₃)₂ + 2AlCl₃
<em>The coefficient is 2.</em>
