Answer:
- <u><em>9.01 g of fertilizer</em></u>
Explanation:
Assume initially that the amount in grams of the multinutrient fertilizer is 100 g, and calculate the amount of nitrogen supplied by every compound present in these 100 g of fertilizer.
<u>1) Urea (CH₄N₂O)</u>:
- Molar mass of urea: 60.06 g/mol
- Atomic mass of N: 14.007 g/mol
- Total mass of N in the formula: 2 × 14.007 g/mol = 28.014 g/mol
- Amount of N in 100 g of compound: 100 g × 54.8% × 28.014 g / 60.06 g = 25.56 g
<u>2) KNO₃</u>
- Molar mass of KNO₃: 101.1032 g/mol
- Atomic mass of N: 14.007 g/ mol
- Total mass of N in the formula: 14.007 g/mol
- Amount of N in 100 of the compound: 100 g × 26.3% × 14.007 / 101.1032 = 3.64 g
<u>3) (NH₄)₂PO₄</u>
- Molar mass of (NH₄)₂PO₄: 132.06 g/mol
- Atomic mass of N: 14.007 g/ mol
- Total mass of N in the formula: 2×14.007 g/mol = 28.014 g/mol
- Amount of N in 100 of the compound: 100 g × 14.1% × 14.007 / 132.06 = 2.99 g
4) <u>Total mass of N in 100 g of fertilizer</u>:
Add all the amounts of N obtained above
- 25.56g + 3.69 g + 2.99 g = 32.19 g of N
5) <u>Mass of fertilizer that should be applied to provide 2.90 g of N to a plant</u>.
Set a proportion:
- 32.19 g of N / 100 g of fertilizer = 2.90 g of N / X
Solve for X:
- X = 2.90 g of N × 100 g of fertilizer / 32.19 g of N = 9.01 g of fertilizer
That is the answer: 9.01 g of fertilizer should be applied to provide 2.90g of N to a plant.
<span> Advantages
- large resource of potential oil
- biggest resource is in Canada, whereas the largest reserves of crude oil are in Saudi Arabia and Venezuela
</span><span><span>- It requires less processing than oil shale and presents fewer problems than oil shale
- Processing is mainly by hot water.</span>- Exploitation has only started recently so low cost reserves are still available.
Disadvantages
- Most of the resource is uneconomic at present oil prices - so exploitable reserves are less than for crude oil
- Oil sands require mining, which is more complex and costly than drilling and pumping crude oil.
- Processing requires more energy than for crude oil.
- Resources are less than for oil shale - which is available in very large reserves in the US and Australia.</span>
<span>- Refining is more difficult because the product is in the form of bitumen - requiring cracking to produce a saleable product.
- because of the increased processing and refining, more carbon is released per unit of useable energy than for crude oil</span>
