Answer:
Check the attached one..I only draw the Dot method of Magnesium and Fluorine.. since i love chemistry ..Hope this helps you...Balance you have to do it yourself..If you didn't get the answer let me know in the comments..But you have try okay..
Answer:
538L of carbon dioxide will be produced
Explanation:
This is a classic example of combustion of an alkane.
If balanced equation is not given; this format can come in handy.
For any alkane of the type : CₙH₂ₙ₊₂ , it's combustion reaction will follow:
2CₙH₂ₙ₊₂ + (3n+1) O₂ → (2n)CO₂ + 2(n+1) H₂O
For ethane:
2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l)
Here, 2 mole of ethane gives 4 moles of CO₂.
or, of ethane gives of CO₂.
Then, 269L of ethane will give:
=
= L
= 538 L
Therefore, 538L of carbon dioxide will be produced
Answer:
Copper
Explanation:
Given parameters:
Mass of metal = 25g
Volume of metal = 2.83cm³
Unknown:
Density of the metal = ?
Solution:
Density is the mass unit volume of a substance. To solve this problem, use the mathematical expression below;
Density =
mass is the amount of substance in the metal
volume is the space occupied by the metal
Now solve;
Density = = 8.83g/cm³
The metal is Copper
The ans: None of the above
