Answer:
We can see that the energy and mass are transformed in other forms via cellular respiration and photosynthesis. Plants breathe carbon dioxide and expel oxygen.
Explanation:
Photosynthesis is where a plant takes light from the sun, water from the soil, and carbon dioxide from the air, and turns it into two things: glucose, which it uses for energy, and oxygen, which it releases into the air. ... Matter and energy is neither created nor destroyed, so it all has to go somewhere

Answer: Molarity of anions in the chemist's solution is 0.0104 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute
= volume of solution in ml = 100 ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution will be
As 1 mole of gives 2 moles of
Thus moles of
gives =
Thus the molarity of anions in the chemist's solution is 0.0104 M
Answer:
Following are the answer to this question:
Explanation:
The value of pH solution is =5.17 So, the p^{OH}:
=14-56.17
=8.823
The volume of the = 40.00 ml
convert into the liter= 0.040L
The value of the concentrated =0.10 M
The volume of the = 50.00 ml
convert into the liter= 0.050L
The value of concentrated = 0.10 M
The volume of the = 30 ml
convert into the liter= 0.030L
The value of concentrated =0.05 M
Calculating total volume=(0.40+0.050+0.030)
=0.120 L
calculating the new concentrated value of =
calculating the new concentrated value of =
calculating the new concentrated value of
when 1 mol
produced 2 mols
so, 0.0125 in
produced:
create the ICE table:
I (m) 0.033(m) 0.025 0.04166
C -0.025 -0.025 + 0.025
E 8.3\times 10^{-3} 0 0.0667
now calculating pH:
when ph= 8.83:
