Hello!
In this case, since the reaction between sulfuric acid and aluminum hydroxide is:
Whereas the ratio of sulfuric acid to aluminum hydroxide is 3:2; thus, we first compute the moles of sulfuric acid that complete react with 3.209 g of aluminum hydroxide:
Then, given the molarity, it is possible to obtain the milliliters as follows:
Best regards!
Answer: 3.5 moles V2O5
Explanation: First balance the chemical equation to find the stoichiometric factor between VOCl3 and V2O5
2 V2O5 + 6 Cl2 => 4 VOCl3 + 7 O2
So the mole to mole ratio is 2 moles V2O5 to 4 moles of VOCl3
Solution
7 moles VOCl3 x 2 moles V2O5 / 4 moles VOCl3 = 3.5 moles V2O5
Answer:
Ice is less dense than water because of the way it forms a hexagonal crystalline structure. Each water molecule consists of two hydrogen atoms bonded to the bottom of an oxygen atom. ... In the winter, temperatures in a lake get close enough to freezing that the colder water is less dense and floats to the top
