Answer:
Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.
Explanation:
Explanation:
Let us assume that the given data is as follows.
mass of barium acetate = 2.19 g
volume = 150 ml = 0.150 L (as 1 L = 1000 ml)
concentration of the aqueous solution = 0.10 M
Therefore, the reaction equation will be as follows.
![Ba(C_{2}H_{3}O_{2})_{2} \rightarrow Ba^{2+} + 2C_{2}H_{3}O^{-}_{2}](https://tex.z-dn.net/?f=Ba%28C_%7B2%7DH_%7B3%7DO_%7B2%7D%29_%7B2%7D%20%5Crightarrow%20Ba%5E%7B2%2B%7D%20%2B%202C_%7B2%7DH_%7B3%7DO%5E%7B-%7D_%7B2%7D)
Hence, moles of
=
.......... (1)
As, No. of moles =
Hence, moles of
will be calculated as follows.
No. of moles =
=
(molar mass of
is 255.415 g/mol)
= ![8.57 \times 10^{-3}](https://tex.z-dn.net/?f=8.57%20%5Ctimes%2010%5E%7B-3%7D)
Moles of
= ![2 \times 8.57 \times 10^{-3}](https://tex.z-dn.net/?f=2%20%5Ctimes%208.57%20%5Ctimes%2010%5E%7B-3%7D)
= 0.01715 mol
Hence, final molarity will be as follows.
Molarity = ![\frac{\text{no. of moles}}{volume}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bno.%20of%20moles%7D%7D%7Bvolume%7D)
= ![\frac{0.01715 mol}{0.150 L}](https://tex.z-dn.net/?f=%5Cfrac%7B0.01715%20mol%7D%7B0.150%20L%7D)
= 0.114 M
Thus, we can conclude that final molarity of barium cation in the solution is 0.114 M.
Answer:
A
Explanation:
Ductility, because it can be observed by altering the shape of the substance
It is equal to a gram, as there are 1,000,000 milligrams in a gram.
