2K + 2H2O -----> 2KOH + H2
The question is telling you what are the reactants and products .
The H3O in a solution is 12.57.
<u>Explanation</u>:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH.
pOH = -log[H3O]
pOH = -log(3.75x10^-2)
= 1.43
Now, pH = 14 - 1.43
= 12.57
The H3O in a solution is 12.57.
Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.
Answer:
The lung
Explanation:
The model of the respiratory system made by Megan consists of two balloons. The first balloon stretched across the bottom of the bottle represents the diaphragm which contracts and relaxes to allow air in and out of the lungs. The balloon inside the bottle represents one lung.
Breathing in causes the balloon inside the bottle to be filled with air. This is preceded by the expansion of the diaphragm which makes the lungs to be filled with air. Breathing out causes a contraction of the diaphragm thus making the lungs to let out air.
