The balanced chemical reaction is:
4Al + 3O2 = 2Al2O3
We are given the amount of reactants to be used for the reaction. These amounts will be the starting point for the calculations. The mole ratio of the reactant is 4:3. Therefore, the limiting reactant is aluminum.
1.60 mol Al ( 2 mol Al2O3 / 4 mol Al ) = 0.8 mol Al2O3
Answer:
A Punnet Square...the second I am not sure.
Explanation:
Unfortunately the second could be many things. You'd have to have more background information.
Carbon dioxide + water → glucose + oxygen + water
I am guessing that your solutions of HCl and of NaOH have approximately the same concentrations. Then the equivalence point will occur at pH 7 near 25 mL NaOH.
The steps are already in the correct order.
1. Record the pH when you have added 0 mL of NaOH to your beaker containing 25 mL of HCl and 25 mL of deionized water.
2. Record the pH of your partially neutralized HCl solution when you have added 5.00 mL of NaOH from the buret.
3. Record the pH of your partially neutralized HCl solution when you have added 10.00 mL, 15.00 mL and 20.00 mL of NaOH.
4. Record the NaOH of your partially neutralized HCl solution when you have added 21.00 mL, 22.00 mL, 23.00 mL and 24.00 mL of NaOH.
5. Add NaOH one drop at a time until you reach a pH of 7.00, then record the volume of NaOH added from the buret ( at about 25 mL).
6. Record the pH of your basic HCl-NaOH solution when you have added 26.00 mL, 27.00 mL, 28.00 mL, 29.00 mL and 30.00 mL of NaOH.
7. Record the pH of your basic HCl-NaOH solution when you have added 35.00 mL, 40.00 mL, 45.00 mL and 50.00 mL of NaOH from your 50mL buret.
Answer:
animal cells dont have chloroplast
Explanation:
chloroplast is used to produce chlorophyll, only something found in plant cells
