Answer:
The flask that produces the largest quantity of product is the second flask
The molecules of H 2 O formed is
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 of that substance
Here is the Avogadro number with the value
So
Looking at the balanced equation we see that 3 moles of O 2 (3 * 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
=>
Answer:
HBr(aq) + LiOH(aq) → LiBr(aq) + H2O(l)
Explanation:
A neutralization reaction is a process in which an acid, aqeous HBr reacts completely with an appropriate amount of base, aqueous LiOH to produce salt, aqueous LiBr and water, liquid H2O only.
HBr(aq) + LiOH(aq) → LiBr(aq) + H2O(l)
Acid + base → Salt + Water.
During this reaction, the hydrogen ion, H+, from the HBr is neutralized by the hydroxide ion, OH-, from the LiOH to form the water molecule, H2O.
Thus, it is called a neutralization reaction.
Answer:
The correct answer is A) circulatory
Explanation:
The circulatory system collects metabolic wastes from the blood, which will be eliminated by the kidneys through urine.
The kidneys are responsible for the elimination of waste, acids and excess fluid from the body, maintaining the balance of water, salts and minerals. Blood flows into the kidney through the renal artery.
