Answer:

pH = 10

Explanation:

As the problem states, with strong bases<em> the hydroxide ion concentration [OH⁻] is equal to the concentration of the base</em>. That means that in this case:

  • [OH⁻] = 0.0001 M

With [OH⁻] we can <u>calculate the pOH of the solution</u>:

  • pOH = -log[OH⁻]
  • pOH = 4

Then with the pOH, we <u>calculate the pH of the solution</u>:

  • pH = 14 - pOH
  • pH = 10

How many Br atoms are in 1.98 g of Br?
Mkey [24]

Answer:

1.5 x 10²²atoms

Explanation:

Given parameters:

Mass of Br = 1.98g

Unknown:

Number of atoms

Solution:

A mole of a substance is the amount of substance contained in the avogadro's number of particles.

To solve this problem, we must first find the number of moles present in the given mass of the Br atom:

       Number of moles = \frac{mass}{molar mass} =  \frac{1.98}{80}  = 0.025mole.

Now we know that:

       1 mole = 6.02 x 10²³

      0.025 mole = 0.025 x 6.02 x 10²³ = 1.5 x 10²²atoms

aev [14]
Radio   wave  eliminate  band (answer  c) is  smallest   within  electromagnetic  spectrum.
  
   The  electromagnetic  spectrum  is  the  range  of  frequencies  (the  spectrum)  of    electromagnetic  radiation   and  their  respective  wavelength and  photon  energies.  The   electromagnetic  spectrum  range from   radio  waves  to  gamma  rays.Radio waves  has  the  shortest  wavelength  while   gamma rays  has  highest.
