Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions.
Answer:
34 g of water, will be produced
Explanation:
The balanced equation for production of water with oxygen is:
2H₂ (g) + O₂ (g) → 2H₂O (l)
2 mol of hydrgen gas react with 1 mol of oxygen to produce 2 moles of water.
Let's determine the moles of O₂ (mass / molar mass)
30 g / 32g/mol = 0.9375 moles
Ratio is 1:2. So If I have x moles of oxygen I would produce the double of moles of water.
0.9375 moles . 2 = 1.875 moles
Let's convert the moles to mass ( mol . molar mass)
1.875 mol . 18g/mol = 33.75 g ≅ 34 g
