Molar mass of :

O2 = 16 * 2 = 32 g/mol

CO2 = 12 + 16 * 2 = 44 g/mol

<span>Balanced chemical equation :
</span>
1 CH4 + 2 O2 = 1 CO2 + 2 H2O
               ↓              ↓
             2 moles     1 mole

2* 32 g O2 ----------> 1* 44 g CO2
     x g O2 ------------> 10.0 g CO2

44 x = 2 * 32*10.0

44 x = 640

x =  \frac{640}{44}

x = 14.54 g of O2

After precipitation falls, the water moves into the lithosphere through
Pie

After precipitation falls, the water moves into the lithosphere through openings in the rock or soil. This process is called percolation.

Therefore, Option C is the correct option.

<h3>What is Evaporation? </h3>

Evaporation is defined as the process of conversion of liquid into vapours.

For example: Conversation of water into water vapours.

But int he question, there is no conversion. So this option is incorrect option.

<h3>What is Sublimation?</h3>

Sublimation is the process of conversion of solid directly into the vapour phase

Since, there is no conversion of of solid into vapours. So, this option also incorrect option.

<h3>What is Mineralization? </h3>

Mineralization is defined as the process through which chemicals which is present in organic matter are decomposed or oxidized easily in the available forms to plants.

As there is no decomposition of minerals. So, this is also incorrect option.

<h3>What is Percolation? </h3>

Percolation is defined as the process in which liquid slowly allow to pass through a filter.

So, this is correct option.

Thus, we concluded that the water moves into the lithosphere through openings in the rock or soil. This process is called percolation.

An unknown substance is found to have a hydrogen concentration of 1.2 * 10 ^ - 2 , what is the pOH? Is it acidic or basic?
Alex_Xolod [135]

Answer:

12.1; acidic

Explanation:

I'm assuming the hydrogen concentration is H+.

So, first we must find pH.

pH = -log[H+]

I simply just plugged in the concentration.

I get 1.9 as the pH. This means that the substance is very acidic since it has a low pH.

Now to find poH.

poH + pH = 14

I simply plugged in once again!

I get 12.1 as the poH. This also determines that the substance is very acidic since it has a high poH.
