Answer:
FBr is a chemical formula representing "flourine monobromide."
Explanation:
Of course, FBR could represent a number of things, from the Federal Board of Revenue to a fluidized bed reactor. I gave the answer I did because you listed this question as Chemisty.
Atoum is the process of how large molecules are formed
Moles of Carbon dioxide : 0.75
<h3>Further explanation</h3>
Given
23 g C₃H₈O₃
Required
Moles of Carbon dioxide
Solution
Reaction
2C₃H₈O₃ + 7O₂ → 6CO₂ + 8H₂O
mol C₃H₈O₃ :
= mass : MW
= 23 g : 92,09382 g/mol
= 0.24975
From the equation, mol ratio of C₃H₈O₃ : 3CO₂ = 1 : 3, so mol CO₂ :
= 3/1 x mol C₃H₈O₃
= 3/1 x 0.24975
= 0.74925≈0.750 mol
H2 has the lowest boiling point.
Answer:
D) 7 before and 7 after
Step-by-step explanation:
Na₂O + 2HCl ⟶ 2NaCl + H₂O
3 atoms + 4 atoms ⟶ 2×2 atoms + 3 atoms
7 atoms ⟶ 4 atoms + 3 atoms
7 atoms ⟶ 7 atoms
There are seven atoms present before and after the reaction.
