Answer:
2:1
1.2 × 10² g
Explanation:
Step 1: Write the balanced combustion equation
CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to CH₄ is 2:1.
Step 3: Calculate the moles of CH₄ required to react with 15 moles of O₂
We will use the previously established molar ratio.
15 mol O₂ 1 mol CH₄/2 mol O₂ = 7.5 mol CH₄
Step 4: Calculate the mass corresponding to 7.5 moles of CH₄
The molar mass of CH₄ is 16.04 g/mol.
7.5 mol × 16.04 g/mol = 1.2 × 10² g
Answer:
Prevailing winds
Presence of mountains
Seasonal winds.
Explanation:
Prevailing winds:
Prevailing winds is the wind that blows across an area or surface over time. It affects the amount of precipitation. If winds blows inland from water bodies such as oceans the amount do precipitation will be high because they carry more water vapor than the winds that blow over land.
Presence of mountains :
Mountain ranges affect precipitation too.The windward side of the mountain, which is the side the wind hits has higher precipitation while the land on the other side of the mountain, leeward side, will have little precipitation.
