Answer: Yes this chemical reaction obeys the laws of physics. Its very simple, let me explain.
Explanation:
When Iron(Fe) oxidizes it gains three oxygen atoms so it reacts to form Fe2O3 so it becomes bigger or explands. Its also sometimes called "oxide jacking".
 
        
             
        
        
        
Answer:
Temporal partitioning or niche differentiation
Explanation:
Temporal partitioning refers to the variability in the competitive abilities of different species competing for the same resources based on varying conditions of the environment. 
The environmental factors could be light, temperature, moisture, etc. Each species specializes in feeding within varied condition of one or more of the factors. 
<em>In this case, both species are in competition but while the first species feeds during the day, the second species feeds during the night. Here, light and temperature probably plays a huge factor.</em>
Temporal partitioning is also known as niche differentiation, segregation, separation or niche partitioning.

Explanation:
It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.
If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.
At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E. 
The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
 
        
             
        
        
        
Answer:
During normal human respiration, glucose (a type of sugar that you get from food) reacts with oxygen to produce energy. The energy is needed for growth, repair and movement. Water and carbon dioxide are bi-products of respiration. they need to be excreted.

Answer: It is a physical change.
Explanation:
Even though they make  sand which they are still meat bread and cheese.  The reactants stay as there ware even though they have taken a different form.  It is like boiling water or freezing it. They look different but the reactants stay the same.
