In a chemical reaction, 10 moles of the element aluminum react with 7.5 moles of oxygen gas. This produces 5 moles of aluminum oxide (Al2O3).
20Al + 15O2 → 10Al2O3
4Al + 3O2 → 2Al2O3
Al + O2 → Al2O3
10Al + 7.5O2 → 5Al2O3
D?10Al + 7.5O2 → 5Al2O3
Dude, all we want is the answer to the freakining equation
It's B, the 4AI + 3O2 --->2A would be the lowest. If you would just explain and give the answer learning would be easier.
BOBSLAYER Here, Bob has a bad habit of writing noting import, and wasting most of our time as we read his useless teaching.
im done with this website you guys suck
D? Yes, I would definitely choose D! "10Al + 7.5O2 → 5Al2O3" is the correct chemical equation for the reaction described. It shows that 10 moles of aluminum react with 7.5 moles of oxygen gas to produce 5 moles of aluminum oxide. It's like the perfect recipe for making aluminum oxide. Bon appé!
To determine the balanced chemical equation for the reaction, we need to ensure that the number of each type of atom is the same on both sides of the equation. Let's go through the options and see which one satisfies this condition.
Option A: 20Al + 15O2 → 10Al2O3
In this equation, there are 20 moles of aluminum on the left side and only 10 moles of aluminum oxide on the right side. Therefore, this equation is not balanced.
Option B: 4Al + 3O2 → 2Al2O3
In this equation, there are 4 moles of aluminum on the left side and 4 moles of aluminum on the right side. However, there are only 3 moles of oxygen on the left side and 2 moles of oxygen in the product. Therefore, this equation is also not balanced.
Option C: Al + O2 → Al2O3
In this equation, there is 1 mole of aluminum on each side, but there are 2 moles of oxygen on the left side and only 1 mole of oxygen in the product. Therefore, this equation is not balanced.
Option D: 10Al + 7.5O2 → 5Al2O3
In this equation, there are 10 moles of aluminum on each side and 7.5 moles of oxygen on the left side and 5 moles of aluminum oxide on the right side, which is balanced and matches the given information. Therefore, option D is the correct balanced chemical equation for the reaction.
So the correct option is:
D) 10Al + 7.5O2 → 5Al2O3
What's the question? I assume you want to know the equation?
Balance the equations. C is not balanced. A, B, D are balanced BUT what is the one with the lowest coefficients?
