PLS HELPPP How many moles of oxygen atoms (not molecules) are present in 6.41×1025 molecules of dinitrogen pentoxide (N2O5)? 1.
olga55 [171]

Answer:

(4) 266 moles

Explanation:

We have Dinitrogen Pentoxide N2O5

6.41*10^25 molecules are given

No of Moles of N2O5 = \frac{No of Molecules }{Avogadro's Number}

                                     = \frac{6.41 * 10^25}{6.022*10^23}

                                      = 106.5 mol

Now using Unitary Method

2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5

1 mole of N = \frac{5}{2}*O

In 106.5 mole of N  = \frac{5}{2}*106.5 = 266.25 mole

So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.

Acids have a high concentration of ...
GrogVix [38]

Answer:

Acids have a high concentration of [H⁺] ions

Explanation:

In order to know about the acids, a solution is acidic when pH < 7

As pH is lower than 7, the pOH > 7

When pH = 7, solution is neutral

When pH is greater than 7, solution is basic

pH = - log [H⁺]

pOH = - log [OH⁻]

Imagine a solution of pure HCl 0.2 M

HCl → H⁺ + OH⁻

[H⁺] = 0.2 M → pH = - log 0.2 → 0.69

pH + pOH = 14

pOH = 14 - 0.69 = 13.31

10^-pOH = [OH⁻] → 10⁻¹³°³¹ = 4.89ₓ10⁻¹⁴

In conclussion [H⁺] > [OH⁻]
