Explanation: Ovaries are part of the female reproductive organ which produces eggs cells female gametes. These kind og gametes produces estrogen a hormone commonly found on females.
Answer:
4
Explanation:
because it has 3 carbons and 6 hydrogen
hope this helps :)
Answer:
To predict the number of shearing electron between the two atoms (ionic bond) the concept of electronegativity is used.In the other words the ability of atoms to attracts the electron is known as electronegativity of the atom.
If the electronegativity between two atoms is greater than 1.7 then these types of bond is known as ionic bond.These types of bond will show ionic character.
First, we are going to use H-H equation :
when PH = Pka + ㏒ [acetate / acetic acid]
when we have Ka value = 1.8 x 10^-5 so, we can get the Pka value:
Pka = - ㏒Ka
= - ㏒ 1.8 x 10^-5
= 4.74
by substitution:
∴ 4.58 = 4.74 + ㏒[acetate / acetic acid]
∴acetate/acetic acid = 0.692
so we need moles of acetate = volume *molarity
= 0.5 L * 0.25 M
= 0.125 moles
when the acetate/ acetic acid ratio = 0.692 and moles acetate = 0.125 moles
∴ moles acetic acid = 0.125 moles / 0.692 moles = 0.182 moles
∴ volume use for 0.182 moles = 0.182 / 0.5 = 0.364 L
∴volume of buffer solution = 0.5 L + 0.364L
= 0.864 L
The 2 indicates the amount of hydrogen there is. In this case there are two atoms of hydrogen. The subscript will correspond to the “letter” (element symbol) right before it.
