Answer:
equal to
Explanation:
The law of conservation of mass tells us that during a chemical reaction, matter cannot be created or destroyed, but it can change from one form to another. This means that while atoms can rearrange themselves into new substances during a reaction, the mass of the reactants and products will be the same.
3.4 X 10^-2 because you start your equation with 2.5g in your (what we call train tracks). Then you have to find the GFM (gram formula mass) of KCl (potassium chloride). You find this by adding the average atomic mass of each element. Potassium's is 39.10 and Chlorine's is 35.45 which gives you a total of 74.55 grams per mol. so now that you have found the GFM you plug that number into the diagonal bottom in order to cancel the gram units. Then you would place 1 mol KCl on top because that is the unit you want. Finally you will divide your original 2.5 by the GFM of 74.55 to get an answer of 0.033534 mol KCl... but since sig figs matter your final answer will be 3.4 X 10^-2
Your body is slowly failing and becoming weaken to the onslaught of the disease you are fighting, till one by one your major components of life start to fail until death comes if it is serious enough.
