The molecular formula of a compound having the empirical formula C9H17O is calculated as below
(C9H17O)n =847.56
{(12 x9 + 1 x17 + 1 x16)}n= 847.56
147 n = 847.56
divide bot
h side by 147
n= 6
(C9H17O)6 therefore the molecular formula = C54H102O6
Answer:
HCl, also known as hydrochloric acid, has a covalent bond. The hydrogen (H) atom shares an electron with the chlorine (Cl) to form the bond.
Explanation:
Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond. The molecule is represented by the conventional Lewis structure, even though the shared electron pair is associated to a larger extent with chlorine than with hydrogen.
Answer:
The answer to your question is Propane
Explanation:
Data
mass of Propane = 3 g
mass of Oxygen = 10 g
limiting reactant = ?
Balanced chemical reaction
C₃H₈ + O₂ ⇒ H₂O + CO₂
Process
1.- Calculate the molar mass of the reactants
C₃H₈ = (12 x 3) + (8 x 1) = 36 + 8 = 44 g
O₂ = 16 x 2 = 32 g
2.- Calculate the theoretical yield C₃H₈ / O₂ = 44/32 = 1.375
3.- Calculate the experimental yield C₃H₈/O₂ = 3/10 = 0.3
4.- Conclusion
The limiting reactant is Propane because the experimental yield was lower than the theoretical yield.
Prokaryotes are usually unicellular - and so would not have tissue, organs or organ systems.Some prokaryotes are multicellular, and you could potentially say that they are a tissue (many similar cells working together to perform a task). However, no prokaryotes have organs or organ systems.
Four people weigh a standard mass of 10.00 g on the same balance. The set of readings suggest measurements that are neither precise <span>nor accurate is the one with less mass</span>
