Question 1: The average human requires 120.0 g of glucose (C6H12O6) per day. How many grams of CO2 (in the photosynthesis reaction) are required in order to produce this amount of glucose?

The photosynthesis reaction is: 6CO2+6H2O→C6H12O6+6O2

Question 2: Molten iron and carbon monoxide are produced in a blast furnace by the reaction of iron (III) oxide and coke (pure carbon). If 25.0 mol of pure Fe2O3 is used, how many grams of iron can be produced? The reaction is:  Fe2O3 + 3 C → 2 Fe + 3 CO

Question 3: Bauxite ore contains aluminium oxide, which is decomposed using electricity to produce aluminium metal. How many moles of aluminium metal can be produced if 100 g of oxygen is released?

Question 4: Determine the mass of oxygen required to completely burn 10.0 g of propane (C3H8).

Question 5: Predict the mass of hydrogen gas produced when 2.73 g of aluminium reacts in a single replacement reaction with excess sulphuric acid

please show your work! thank you!

 If you were to start with 1.00 g of salicylic acid, what volume of acetic anhydride would be

needed to completely react with it? The density of acetic anhydride is 1.082 g/mL

Lithium aluminum hydride (LiAlH₄) readily reduces the C=O double bond of aldehydes and ketones to the corresponding alcohols whereas the reduction of alkenes is unfavorable. Briefly state the reason for the differential reactivity.

if 5% nacl solution use to regeneration of zeolite,it is capable to removing.....mg caco3 equivalent hardness per lit

80cm³ mixture of propane and hydrogen was mixed with excess oxygen and exploded. The product after cooling to the original room temperature were treated with excess potassium hydro oxide solution when the volume decrease by 60cm³. Calculate the composition of the original mixture

6.Draw galvanic cells based on the net ionic equations for the following reactions. For each reaction:

• Label the anode and cathode.
• Write the oxidation and reduction half reactions for the cell.
• Indicate the electrode materials, and electrolyte components.
• Indicate the direction of electron flow and ion migration.

Note: The spectator ion in each reaction is SO₄^2-. Draw the galvanic cells using a salt bridge with Na₂SO₄ as the electrolyte.

a. Fe + Sn2+ = Fe2+ + Sn

b. Al + 3Ag1+ = Al3+ + 3Ag

c. Mg + Fe2+ = Mg2+ + Fe

= means arrows like these as well just in case it’s confusing -->

7. Write the cell notation for each cell in question 6.
