Answer:
18.82L of oxygen gas are needed.
Explanation:
1st) It is necessary to write and balance the chemical reaction:
2nd) From the balanced reaction, we can see that 3 moles of oxygen gas (O2) react with 4 moles of aluminum (Al). To convert moles to grams, it is necessary to use the molar mass of oxygen (32g/mol) and aluminum (27g/mol):
- O2 conversion:
- Al conversion:
Now we can see that 96g of O2 react with 108g of Al.
3rd) We have to calculate the grams of O2 that will react with 30.25g of Al:
Using the molar mass of oxygen, we know that 26.89g represent 0.84 moles of O2.
4th) Finally, a mole of a gas at STP conditions occupies a volume of 22.4L. With this number and the moles of oxygen gas, we can calculate the liters:
So, 18.82L of oxygen gas are needed.
Answer:
Volume in L = 0.028 L
Explanation:
Given data:
Mass of copper phosphate = 27.6 g
Molarity solution = 6.03 M
Volume of solution = ?
Solution:
First of all we will calculate the number of moles of copper phosphate.
Number of moles = mass/molar mass
Number of moles = 27.6 g/ 159.61 g/mol
Number of moles = 0.17 mol
Volume of solution:
Molarity = number of moles / volume in L
By putting values,
6.03 M = 0.17 mol / volume in L
Volume in L = 0.17 mol / 6.03 M
Volume in L = 0.028 L
The act of using senses or tools to gather information is making an observation
Layer 5 would be the most likely. The shift up into layer 6 would both mix the already found fossils and its own. Plus, the layers are close as it is
I hope this helps!
