Answer:

Caves.

Explanation:

Hello,

In this case, caves are formed by the dissolution of limestone. It turns out that rainwater picks up carbon dioxide from the air and as it percolates through the soil it turns into a weak acid (carbonic acid). This causes a slowly dissolution of the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

Best regards.

The answer is Caverns

as Caverns of limestone is a natural cavity, which forms in the subsurface of the earth by the effect of acidic groundwater and underground water (like rivers) making the limestone dissolve by time and leaves this cavity. which increase and grow up with time.
and there are many structures which form in this caverns ex :
(Speleothem, Stalactite, Flowstone, Stalagmite, Helictite)

koban [17]

Answer:

Diagram 1

Explanation:

The solubility of the oxygen gas in water has to do with the interaction of the oxygen with the dipoles in water.

Water is a polar molecule having oxygen as the negative dipole and hydrogen as the positive dipole.

Water can interact with the oxygen atoms in the molecule via intermolecular hydrogen bonds with molecular oxygen as shown in diagram 1.

We know that density = mass /volume
so
mass=volume*density
volume=mass/density
so c is wrong

Which of the following coefficients are needed to balance the combustion reaction of ethanol?

djyliett [7]

Answer is: d. 3,2,3.

Balanced chemical reaction: CH₃CH₂OH + 3O₂ → 2CO₂ + 3H₂O.
CH₃CH₂OH is ethanol.
O₂ is molecule of oxygen.
CO₂ is carbon(IV) oxide.
H₂O is water.
There are same number of atoms (oxygen, carbon and hydrogen) on both side of balanced chemical reaction:
2 atoms of carbon.
6 atoms of hydrogen.
7 atoms of oxygen.

7 f Find the volume in dm3 and in mole of 0.505m of NaoH required to react with 40ml of 0.505m

Anna [14]

The volume of NaOH required is 0.08 dm³

To solve this question, we'll begin by writing the balanced equation for the reaction between H₂SO₄ and NaOH. This is illustrated below:

H₂SO₄ + 2NaOH —> Na₂SO₄ + 2H₂O

From the balanced equation above,

Mole ratio of the acid, H₂SO₄ $(n_{A}) = 1$

Mole ratio of the base, NaOH $(n_{B}) = 2$

Next, we shall determine the volume of NaOH required to react with H₂SO₄. This can be obtained as follow:

Molarity of the base, NaOH $(M_{B}) = 0.505 M$

Volume of the acid, H₂SO₄ $(V_{A}) = 40 mL$

Molarity of the acid, H₂SO₄ $(M_{A}) = 0.505 M$

<h3>Volume of the base, NaOH $(V_{B})$ =? </h3>

$\frac{M_{A} * V_{A}}{M_{B} * V_{B}} = \frac{n_{A}}{n_{B}}\\\\\frac{0.505 * 40}{0.505 *V_{B}} = \frac{1}{2}\\\\\frac{20.2}{0.505 *V_{B}} = \frac{1}{2}$
