3 0

Answer:

CO2 is an evil necessary element. co2 is needed for our survival. we need food for survival and food is produced by the plants through photosynthesis. for photosynthesis to take place co2 is one of the vital element. so no co2,no photosyntheseis maeans no food. no food no one will survive.

How Do You Know Whether an Object Has Potential
timofeeve [1]

The object that I think has potential energy within the images posted is the skateboard at the top of the ramp.

<h3>Why do i think this one has potential energy?</h3>

Potential energy is a type of mechanical energy in which there is a type of stored energy that can be transformed into another type of energy. This energy is given by the <u>location of the body</u> with respect to a force field.

I selected the image of the skateboard at the top of the ramp since going up there uses kinetic energy and when it is on top of the ramp, waiting to go down, this kinetic energy is stored in potential energy that is ready to be released. The higher the height at which it is launched, <u>the more its potential energy will be</u>.

Therefore, we can confirm that the object that I think has potential energy within the images posted is the skateboard at the top of the ramp.

Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water.
Marrrta [24]

Hello, this question is incomplete. The complete question would be:

"Write the balanced chemical equation for the following reaction.

Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water"

Answer:

Fe2O3 + 3 H2 = 2 Fe + 3 H2O

Explanation:

In a chemical reaction, the structure of atoms as chemical elements is unchanged. Atoms in one element do not become atoms in another element. There is also no loss or creation of new atoms. The number of atoms of the reagents must be equal to the number of atoms of the products. When this happens, we say that the chemical equation is balanced.

For this reason, we can state that the balanced chemical reaction where solid iron (III) oxide reacts with hydrogen gas to form solid iron and liquid water would be:

<em>Fe2O3 + 3 H2 = 2 Fe + 3 H2O </em>

When titrating a NaF(aq) solution with HCl(aq), the equivalence point will occur at a pH value ______ .
Gelneren [198K]

At the equivalence point, the NaF completely reacts with the HCl

The correct option that gives the equivalence point when titrating NaF solution with HCl(aq), occur at a pH value is option c);

c) <u>Below 7 because it is determined by HF (aq)</u>

Reason:

The ionic equation of the reaction taking place in the titration is presented as follows;

  • NaF + HCl → HF + NaCl
  • Na⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → HF (aq)+ Na⁺(aq) + Cl⁻(aq)

Therefore, by removing the spectator ions, we get;

  • F⁻(aq) + H⁺(aq) → HF(aq)

Therefore;

The net ionic equation is the formation of hydrofluoric acid, HF, which is a

weak acid, therefore, the pH value will be <u>below 7 because it is determined </u>

<u>by HF</u>
