Answer:

yes, they are ph sensitive

Explanation:

Plants and animals are known to show growth sensitive to pH. pH is known as the hydrogen ion concentration of a solution. For example, plants are known to be growth sensitive to the pH of the soil. Plants need an optimum pH of soil for their growth, hence, showing growth dependence on soil pH.

For each given [H3O+] or [OH-], find the corresponding [OH-] or [H3O+] at 25°C.
-BARSIC- [3]

Answer:

a) [H3O+] = 1.00 E-10 M ⇒ [OH-] = 1.0 E-4 M

b) [H3O+] = 1.00 E-4 M ⇒ [OH-] = 1.0 E-10 M

c) [H3O+] = 9.90 E-6 M ⇒ [OH-] = 1.0 E-9 M

Explanation:

  • 14 = pH + pOH
  • pH = - Log [H3O+]

a) [H3O+] = 1.00 E-10 M

⇒ pH = - Log(1.00 E-10) = 10

⇒ pOH = 14 - 10 = 4

⇒ 4 = - Log[OH-]

⇒ [OH-] = 1.0 E-4 M

b) [H3O+] = 1.00 E-4 M

⇒ pH = 4

⇒ pOH = 10

⇒ [OH-] = 1.0 E-10 M

c) [H3O+] = 9.90 E-6 M

⇒ pH = 5

⇒ pOH = 9

⇒ [OH-] = 1.0 E-9 M

How many moles are in a sample of 1.52 x 1024 atoms of mercury (Hg)?
OLEGan [10]

The answer is:

2.5 moles

The explanation:

when avogadro's number = 6.02 * 10^23

and when 1 mole of the sample will give → 6.02*10^23 atoms

So,        ??? mole of the sample will give→ 1.52 x 10^24 atoms

∴ number of moles = (1.52 X 10^24) * 1 mole / (6.02X10^23)

                                = 2.5 moles

What is the appropriate chemical formula for Iron(III) Sulfate? Sulfate is SO_4^2 Fe3SO4 O a . Fe2(SO4)3 O b. O c. Fe2SO4 O d. F
AnnyKZ [126]

<u>Answer:</u> The chemical formula of Iron (III) sulfate is Fe_2(SO_4)_3

<u>Explanation:</u>

Iron is the 26th element of periodic table having electronic configuration of [Ar]3d^64s^2.

To form Fe^{3+} ion, this element will loose 3 electrons.

Sulfate ion is a polyatomic ion having chemical formula of SO_4^{2-}

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for Iron (III) sulfate is Fe_2(SO_4)_3
