Explanation:
A; Animals inhale and exhale, breath oxygen, leave carbon dioxide.
C; We fart, so do they! (farts are a release of methane gas from our bodies) Just ask my dog...
Hope this helped!
Answer:
The concentration of the solution, 
Explanation:
The absorbance of a solution can be calculated by Beer-Lambert's law as:
Where,
A is the absorbance of the solution
ɛ is the molar absorption coefficient (
)
C is the concentration (
)
l is the path length of the cell in which sample is taken (cm)
Given,
A = 0.20
ɛ = 27400 
l = 1 cm
Applying in the above formula for the calculation of concentration as:
So , concentration is:
Answer:
5. A strong base increases the OH- ion concentration in an aqueous solution.
6. It has more hydrogen ions.
Explanation:
5. Arrhenius theory states that acids donate H+ ions to a solution and bases donate OH- ions to a solution.
6. pH < 7 so the solution is acidic. Acidic solutions have more hydrogen or hydronium ions. Hydrogen and hydronium ions are essentially interchangeable.
