Answer:
18 grams of water, will be produced from 4 g of H₂ and 16g of O₂
Explanation:
Reaction: 2H₂ + O₂ ⇒ 2H₂O
Moles = Mass / Molar mass
Molar mass H₂ = 2g/m
Molar mass O₂ = 32 g/m
4g /2g/m = 2moles
16g / 32 g/m = 0.5 moles
Ratio is 2:1
For 2 moles of hydrogen, I need 1 mol of oxygen; I have 2 moles of H₂, but I only have 0.5 of O₂, so the O₂ is the limiting reagent.
1 mol of O₂ produces 2 mol of water
0.5 moles of O₂ will produce, the double → 1 mol of water.
Molar mass of water is 18 g/m
1 mol . 18 g/m = 18 g
I’m assuming it’s type one (most likely) diabetes!
Answer:
If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.
Explanation:
If a planet tilts more, it leads to colder winters and warmer summers. However, if a planet tilts less, it leads to less severe seasons that is and milder winters and cooler summers.
If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.
The first one is the correct answer
