Answer:

8.25 moles of oxygen will be produced.

Explanation:

Given a balanced chemical equation;

2Al₂O₃ ------> 4Al + 3O₂

from the balanced chemical equation above, 3 moles of Oxygen are produced when 4 moles of Aluminum are produced.

4 moles of Al --------> 3 moles of Oxygen

11 moles of Al --------> ?

= \frac{(3 \ moles \ of \ O_2) \ \times \ (11 \ moles \ of \ Al)}{4 \ moles \ of \ Al} = 8.25 \ moles \ of \ O_2 \\\\

Therefore, 8.25 moles of oxygen will be produced.

nexus9112 [7]

Answer:

The corrext answer is E. make; break

Explanation:

In living organisms, the metabolism is either anabolic or catabolic where anabolic metabolism is energy consuming and catabolic metabolism is eneegy releasesing. It should however be noted that anabolic reaction builds or biosynthesize new mollecular structures while catabolic reaction breaks down complex structure bonds into simple structures

The braking down of bonds in catabolic reations realeses energy to sustain the anabolic rection process for the formation of new bonds

Why is a measured amount of water needed to determine the specific heat of a metal object?
shutvik [7]
This  is  because  absorbed  heat  energy or  released  by  water  is dependent on  mass of  water.
q=mc delta  T
where  q is  the amount  of  energy  required,   m  is  the  mass , C  is   the  specific  heat  capacity  and  delta  T is change  in  temperature.
