inna [77]

Answer:

The minerals will not be move or transported to other part of the plants because active transport require energy.

Explanation:

Active transport is a process where molecules and ions are move against a concentration gradient by using energy.

This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.

If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.

2 C2H6 + 702 — 4 CO2 + 6H2O
Andreas93 [3]

We calculate the number of moles of water given its mass by dividing the mass by the molar mass.  

                              n water = (36.04 g) / (18 g/mol)  

                               n water = 2 mols

From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.

                               n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)

                               n oxygen  = 2.33 mols O2
