Answer:
1 mol of water is produced in those conditions.
Explanation:
The reaction to produce water between H₂ and O₂ is this:
2H₂ + O₂ → 2H₂O
We don't have the amount of hydrogen, so we have to think that is in excess.
Let's work with oxygen.
Ratio is 1:2
For 0.5 mole of oxygen, I will make the double of moles of water.
Answer:
Oxidation of potassium amalgam with carbon dioxide results in the formation of potassium oxalate. Potassium is not reactive with benzene, although heavier alkali metals such as cesium react to give organometallic products.

A is correct because the fruit salad can be easily separated and the puch cannot so it is a solution and the fruit salad is a mixture.
Answer:
The volume of the solution is 133 ml
Explanation:
Having a 0.250 molar solution means 0.250 moles in 1000 ml of solution (1 liter)
We calculate the weight of 1 mole of CuNO3, and use 3 simple rules for calculations:
CuNo3---> Weight of 1 mole= 63, 546g+ 14, 0067g+ 3X 15, 9999g= 125, 55g/mol
1 mol----125, 55g
0,250mol---X= (0,250molx 125,55g)/1mol= 31,3 g
31,3g----1000ml
4,16g---x= (4,16gx1000ml)/31,3g = 133ml
