Answer:
Mass number or relative atomic mass number.
The reaction between methanol and oxygen gas produces water vapor and carbon dioxide. 2CH3OH(l)+3O2(g)⟶4H2O(g)+2CO2(g) Three sealed flasks contain different amounts of methanol and oxygen. Based on the molecular view of the three flasks, which would produce the largest quantity of total product? The flask contains 3 molecules of C H 3 O H and 3 molecules of O 2. The flask contains 1 molecule of C H 3 O H and 6 molecules of O 2. The flask contains 4 molecules of C H 3 O H and 2 molecule of O 2. For the flask which produces the largest quantity of total product, how many molecules of H2O will be formed? molecules of H2O :
Answer:
The flask that produces the largest quantity of product is the second flask
The molecules of H 2 O formed is [tex]X = 8 \ molecules [/tex]
Explanation:
From the question we are told that
The reaction is
2CH3OH(l) + 3O2(g)⟶4H2O(g)+2CO2(g)
The first flask contains 3 molecules of C H 3 O H and 3 molecules of O 2
The second flask contains 1 molecule of C H 3 O H and 6 molecules of O 2
The third flask contains 4 molecules of C H 3 O H and 2 molecule of O 2.
Looking at the three flasks we can see that base on molecular view the flask which produces the largest quantity of total product is second flask
From the balanced equation we see that 2 moles of C H 3 O H are required to react with 3 moles of oxygen hence O 2 is the limiting reactant
Generally 1 mole of any substance is [tex]1 * N_A[/tex] of that substance
Here [tex]N_A[/tex] is the Avogadro number with the value [tex]N_A = 6.02214076 * 10^{23} \ molecules[/tex]
So
Looking at the balanced equation we see that 3 moles of O 2 (3 * [tex]N_A[/tex] molecules of O 2 ) produces 4 moles of H2O(4 *
Then 6 molecules of O 2 will produce X molecules of H 2 O
So
[tex]X = \frac{6 * (4 * N_A }{3 * N_A}[/tex]
=> [tex]X = 8 \ molecules [/tex]
Something used to represent a complex idea or process in science is a what
Answer:
a model?
Explanation:
im not sure! i think so
Answer:
Yes, It is a model
Explanation:
A complex idea or a process can be demonstarated by using a Model because you can see things easier and its basically a copy of anything from forests to volcanoes but smaller to make it easier to see.
