An aqueous solution contains 0.397 M ammonia. Calculate the pH of the solution after the addition of 4.63 x 10-2 moles of perchl
SSSSS [86.1K]

Answer:

9.308

Explanation:

The computation of the pH of the given solution is shown below:

But before we need to determine the HI molarity which is

Molarity\ of\ HI = \frac{moles}{volume \ in\ L}

= \frac{4.63\times10^{-2}}{0.250}

= 0.1852  M

Now

As we know that

NH_3 + HI = NH_4I

So,

NH_4I = HI = 0.1852 M

Now the molarity of NH_3 left is

= 0.397 - 0.1852

= 0.2118

pOH = pKb + log (\frac{NH_4I}{NH_3})

= 4.75 + log(\frac{0.1852}{0.2118})

= 4.692

Now as we know that

pH = 14 - pOH

= 14 - pOH

= 14 - 4.692

= 9.308

We simply applied the above equations

What is the difference between a meteor and a meteorite?
nikklg [1K]

Answer:

When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

Explanation:

When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

Soloha48 [4]

White phosphorus melts and then vaporizes at high temperatures. The gas effuses at a rate that is 0.404 times that of neon in the same apparatus under the same conditions-There are 4 atoms of P in the molecule

Explanation:

Ar=30,97g/mol

R_{Px/R_Ne}=\sqrt{Mr(Ne)/Mr(Px)}=0,404

0,404=\sqrt{20,18/30,97*x}

0,404^{2}=20,18/30,97*x

X=20,18/30,97*0,163

X=4

There are 4 atoms of P in the molecule
