The balanced combustion reaction of propane, C₃H₈, is
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
Molar mass of propane: 44 g/mol
Moles of propane = 42 g * (1 mol/44g) = 0.9545 mol propane
Molar mass of oxygen: 32 g/mol
Moles of oxygen = 115 g * (1 mol/32 g) = 3.594 mol oxygen
Moles of oxygen needed to completely react propane:
0.9545 mol propane * (5 mol O₂/1 mol propane) = 4.7725 mol oxygen
Since the available oxygen is only 3.594 moles and propane needs 4.7725 moles, that means oxygen is our limiting reactant. We base the amount of water produced here.
Molar mass of water: 18 g/mol
Mass of water produced = 3.594 mol O₂ * (4 mol H₂O/5 mol O₂) * (18 g/mol)
Mass of water produced = 258.768 grams
Answer:

I only came up with 2 I couldnt think of a third one
Atoms are real even though they're invisible.
Answer:
Climatic condition in coastal regions is milder than the climatic conditions in the continental regions.
Explanation:
Climate in coastal regions is mild. It has both hot summers and winters accompanied by sea breezes. Precipitation and humidity is high in coastal areas. Both the summers and winters have a mild temperature range.
While in continental regions both summer and winters undergo extreme conditions. Summers are extremely hot and winters are extremely cold. They have wide range of climatic exposures such as rainy season, autumn season and spring season in between summer and winter season.
