The needs of future generations
The balanced equation for the combustion of CH₄ is as follows
CH₄ + 2O₂ ---> CO₂ + 2H₂O
stoichiometry of CH₄ to CO₂ is 1:1
therefore molar ratio of CH₄ to CO₂ is 1:1
the number of CH₄ moles combusted - 1.00 mol
number of CO₂ moles formed = number of CH₄ moles reacted
therefore number of CO₂ mol formed - 1.00 mol
mass of CO₂ produced - 1.00 mol x 44 g/mol = 44.0 g
mass of CO₂ produced is 44.0 g
Answer:
A & B: 8
C: O
D: 26
E: 30
F: Fe
Explanation:
the first one is Oxygen, the other is Iron.
When you dissolve an ionic compound into water, the have a tendency to separate from each other. They're still chemically the samething.
LiOH is an ionic compound. Lithium is positive and "borrows" the hydroxide's negative charge to be neutral & vice-versa. When LiOH is dissolved in water the Lithium and the hydroxide separate into their respective forms, also known as ions.
So, LiOH dissolves to become these ions in solution= Li+ and OH-
(the plus and minus represent their charges).
Hope that helps!
