2 Fluorine atoms covalently bonded with each other, each sharing an equal number of a single, one valence electron to achieve a stable octet, would form a diatonic fluorine gas. It is a diatomic molecule, a molecule consisting of 2 atoms that are the same, in this case fluorine.
Step 1: Write Imbalance Equation
CH₃CHO + O₂ → CO₂ + H₂O
Step 2: Balance Carbon Atoms:
There are 2 carbon atoms at reactant side and one at product side. So multiply CO₂ with 2 to balance them. i.e.
CH₃CHO + O₂ → 2 CO₂ + H₂O
Step 3: Balance Hydrogen Atoms:
There are 4 hydrogen atoms at reactant side and 2 Hydrogen atoms at product side. So, multiply H₂O by 2 to balance Hydrogen on both sides. i.e.
CH₃CHO + O₂ → 2 CO₂ + 2 H₂O
Step 4: Balance Oxygen Atoms:
There are 3 Oxygen atoms at reactant side and 6 Oxygen atoms at product side. In order to balance them multiply O₂ on reactant side by 2.5 (5/2). i.e
CH₃CHO + 5/2 O₂ → 2 CO₂ + 2 H₂O
Step 6: Eliminate Fraction:
Multiply overall equation by 2 to eliminate fraction. i.e.
2 CH₃CHO + 5 O₂ → 4 CO₂ + 4 H₂O
Answer:
B
Explanation:
it is the energy stored in the chemical bonds of a substance
Answer:
Hence , in a century<u> 0.342 liters</u> of the liquid will drip.
Explanation:
The rate of the flow of the liquid droplet is given by:
<u>Unit conversion:</u>
We need to change mL/hr into Liter/century
1 L = 1000 mL (given)
1 mL = 0.001 L......(1)
1 century = 100 year
1 year = 365 days
So, 1 century = 100 x 365 days = 36500 days
1 day = 24 hrs
So , 36500 days = 36500 x 24 hr = 876000 hr
Hence ,
1 century = 36500 days = 876000 hr
we are not asked to calculate the answer in days
1 century = 876000 hr
1 hr = 1/ 876000 century
.....(2)
From (1) and (2) put the value in the given formula:
This is for 1 mL/hr to 1 L/century
Now for 300 mL/hr . the rate will be more , multiply the answer by 300
Rate = 0.342 Liters / century
Hence , in a century 0.342 liters of the liquid will drip.
