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
Silver. It is number 47 on the periodic table meaning it has 47 protons. It’s atomic mass is 108. 47+61=108 so it is definitely silver
Answer:
We call solutions with more H+ than OH- acidic. pH is minus the common (base 10 ) logarithm of the hydrogen ion concentration and pOH is minus the log of the hydroxyl ion concentration. Hence pH + pOH = 14.
