Answer:
1. Based on the given question, 138.03 grams of NO₂ is reacting completely with 18.02 grams of H2O. However, in case when 359 grams of NO₂ is used then the grams of water consumed in the reaction will be,
= 359 × 18.02 / 138.03 = 46.87 grams of water.
2. As mentioned in the given case 138.03 grams of NO₂ generates 126.04 grams of HNO₃. Therefore, 359 grams of NO₂ will produce,
= 359 × 126.04 / 138.03
= 327.81 grams of HNO₃.
3. Based on the given question, 138.04 grams of NO₂ is generating 30.01 grams of NO. Therefore, 359 grams of NO₂ will generate,
= 359 × 30.01 / 138.04
= 78.04 grams of NO.
Answer:
This question is incomplete. A fragment of the question is missing. The fragment is:
She finds that 4.87 g of oxygen gas is produced
0.152 moles
Explanation:
Using the formula: mole = mass / molar mass
According to the question, a chemist measures the amount of oxygen gas produced during an experiment. Oxygen gas has the chemical formula: O2. Hence, the molar mass will be:
O2 = 16(2) = 32g/mol
If the mass of the oxygen gas to be 4.87 g of oxygen gas.
Therefore,
moles = 4.87/32
moles = 0.152mol
