Cellulose, the major component of plant cell walls has an empirical formula of C6H10O5.  One of the largest known Redwood trees, The Lindsey Creek Redwood had a mass of 3.3 x 106 kilograms at the time (1905) it was uprooted and felled by a storm.  Assuming trees are composed of 45 % cellulose, calculate the moles of carbon contained in the cellulose of the Lindsey Creek Redwood.

The 24 power plants in Baltimore metro area collectively emit about 40,300 metric tons of CO2 per day (www.carma.org), thereby increasing the level of greenhouse gases in this region. To counter this, environmentalists plan to plant trees in the area. How many moles of CO2 are emitted by these power plants every day? (1 ton =1000kg, molecular weight of CO2 is 44g) If on average 500 moles of glucose are synthesized by a tree each day, how many moles of CO2 can a single tree convert to glucose in a single day? How many trees need to be planted to reabsorb all the CO2 released into the atmosphere every day by these power plants? If a single tree occupies an average of 8.00 x 10-5 sq miles, what percent of the area of Baltimore city needs to be forested to counter the CO2 emitted from power plants alone?  (total area of Baltimore city is 92.00 sq miles)

Choose the reaction that represents the combustion of C6H1202. C6H12O2(1) + 8 O2(g) →6 CO2(g) + 6 H₂O(g) O Mg(s) + C6H1202(1)→ MgC6H₁202(aq) 6 C(s) + 6 H₂(g) + O2(g) → C6H12O2(1) C6H12O2(1)→6 C(s) + 6 H₂(g) + O2(g) None of these represent the combustion of C6H12O2.

3. What mass of oxygen is produced if 22.7 mol of carbon dioxide is consumed in a controlled photosynthesis reaction? 6CO₂(g) + 6H₂O(l) → C6H12O6(s) + 60₂(g)

Given (8.79x10^6) moles of glucose, C6H12O6, calculate the mole of carbon dioxide, CO2, formed upon complete oxidation of the glucose. C6H12O6   +   6 O2   →   6 CO2   +   6 H2O Express your answer in three significant digits as moles.   Note: Your answer is assumed to be reduced to the highest power possible.

Question 102 of 109 Submit Copper(II) phthalocyanine (Cu(C32H,hoNs)) is produced by the cyclotetramerization of phthalonitrile (CgH,N2) according to the following reaction: CaH,N2(1) + CuCl2(s) → Cu(C32H16N8)(s) + Cl2(g) How many grams of copper(II) phthalocyanine would be produced by the complete cyclotetramerization of 0.299 moles of phthalonitrile in the presence of excess copper(1I) chloride? | g 1 6.

6. Consider the following chemical reaction: 2 Cr(OH)3(aq) >Cr₂O3(s) + 3H₂0(1) 12.00 moles of chromium (III) hydroxide is decomposed. Calculate moles of the water produced. O 18.00 moles O 1.500 moles O 4.00 moles O 12.00 moles

What mass of Cu(IO3)2 can be formed from 0.650 g of CuSO4 · 5H2O? What mass of KIO3 is needed to convert the copper in 0.2750 g of CUSO4 - 5H2O to Cu(IO3)2?
