Answer:
6 moles of electrons are transfered
Explanation:
The actual redox is
S4+ +6e- long arrow S2- + 3O2
From the reaction, addition of 6 electrons on the LHS is needed to balance the electron number, hence 6 moles of electrons are transfered
Membranes provided significant advantages for the survival of organisms and the replication of their genetic material.
One significant advantage was the ability to better regulate and insulate the cells internal environment from the external environment. The cell had better control over the chemical composition and temperature inside its membrane, which made it easier to survive.
Cells with membranes were able to contain their genetic material, ensuring that, when replicated, it was identical to the parent cell. This meant that organisms with better survivability traits passed on their genetic material in a way that better preserved their genes, and by extension these advantageous traits.
These advantages helped cells with membranes to better survive and replicate, and also enabled the more complex cells with advantageous genetic material to better preserve and copy that material to new cells, allowing for a higher probability of reproduction among more complex life forms.
Answer:
Explanation:
Hello.
In this case, given the chemical reaction, we can compute the grams of oxygen by using the 98.2 g of water via the 2:1 mole ratio between them, the molar mass of water that is 18.02 g/mol, the molar mass of gaseous oxygen that is 32.00 g/mol and the following stoichiometric procedure relating the given information:
In which the result is displayed with three significant figures because the given mass of water 98.2 g, has three significant figures too.
Best regards!
