Answer:

A mountain would form on the continental crust

Explanation:

Typically, a convergent plate boundary—such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth’s crust is crumpled and pushed upward.

Find the pH of 8.4x10^-8 M HCl. Report the answer to the hundredths place.

Hunter-Best [27]

Answer:

pH = 7.08

Explanation:

HCl ---------> H^+ + Cl^-

It's an acid, we are using this formula

pH = -log [H]^+

H^+ = 8.4 * 10^-8

pH = - log [8.4 * 10^-8]

It can also be solved as

-log 8.4-(-8log 10)

-0.924-(-8×1)

-0.924+8

7.076

To the nearest hundredth

pH = 7.08

Answer:

K= 25.16%

Mn= 34.59%

O= 40.25%

Explanation:

$KMnO_4$

Find the total mass of the compound. You can do this by multiplying by the molar mass.

$K=40*1=40\\Mn=55*1=55\\O=16*4=64$

add them:

40+55+64=159g

Now convert each element individually to grams using molar mass

$1molK(\frac{40gK}{1molK} )=40gK$

$1molMn(\frac{55gMn}{1molMn} )=55gMn$

$4molO(\frac{16gO}{1molO})=64gO$

Divide by the mass of the compound and multiply by 100

$K=\frac{40g}{159g} *100=25.16$

$Mn=\frac{55g}{159g}*100=34.59$

$O=\frac{64g}{159g}*100=40.25$
