What subject is this again ? If I know now then I would have a better understanding of what I’m gonna answer so you don’t get it wrong !
33.6 moles are needed to completely react with 84.0 moles of O2
use the periodic table to identify an element is by looking for the element's name or elemental symbol.
The deeper you go on the earth you'd then reach the earths core.
Answer:
0.204 mol
Explanation:
Step 1: Write the balanced equation for the heating of calcium chloride dihydrate
CaCl₂.2H₂O ⇒ CaCl₂ + 2H₂O
Step 2: Calculate the moles of calcium chloride dihydrate
The<em> molar mass of CaCl₂.2H₂O</em> is 147.01 g/mol. The moles corresponding to 15.0 g of CaCl₂.2H₂O are:
Step 3: Establish the molar ratio of CaCl₂.2H₂O to H₂O
According to <em>the balanced equation</em>, the molar ratio of CaCl₂.2H₂O to H₂O is 1:2.
Step 4: Use the molar ratio to calculate the moles of water produced from 0.102 moles of calcium chloride dihydrate
