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.
Answer:
1 oxygen atoms
Explanation:
When barium combines with oxygen to form an ionic compound, it will only require just an oxygen atom.
An ionic compound is formed due to the electrostatic attraction between oppositely charged ions
A metal loses electrons to be gained by the non - metal and in the process they attract each other with a force.
Barium has two valence electrons, to be stable, it loses the two;
Oxygen has six valence electrons, to be stable it will gain two valence electrons to form an octet.
So;
One barium atom will successfully bind with One oxygen atom to form
BaO

It’s because sand is a poor conductor of heat so when the sun warms the sand, the heat is not disturbed evenly. Also the specific heat of sand is is lower than that of water.
