erma4kov [3.2K]

Answer: D. Roots

Explanation:

Sophie said that the part in question does not belong to an animal. This therefore invalidates options B and C as only animals would have lungs or legs.

Sophie then says that the part does not grow in the direction of light so that removes stems as the correct option because stems grow towards light in order to allow leaves to carry out photosynthesis.

Roots on the other hand grow towards gravity so they grow away from light which means that the correct answer is roots.

Consider the following reaction:
Katyanochek1 [597]

Answer:

The three statements are true

Explanation:

For the reaction:

I₂O₅(s) + 5CO(g) → I₂(s) + 5CO₂(g)

State oxidation of iodine in I₂O₅ is:

5 O²⁻ = 10⁻

As you have 2 I and the molecule has no charge, <em>oxidation state of I is +5</em>.

The carbon in CO has an oxidation state of +2 and in CO₂ is +4. That means <em>the carbon is oxidized</em>

<em />

An oxidizing agent is a substance that produce the oxidation of the agent that reacts with this one. CO is oxidized because of I₂O₅ is producing its oxidation being <em>the oxidizing agent</em>

<em></em>

Thus,<em> the three statements are true</em>.

Which compound is used to make asphalt?
Masteriza [31]
Asphalt is a biproduct of making gasoline, diesel, kerosene, jet fuel, all from crude oil pumped from the ground. Asphalt is the garbage or waste that comes out the bottom of the process of distilling those products. They heat the thick oily-sooty gunky asphalt and mix it with rock or sand and make roads out of it. So the compound would be the long hydrocarbon chains.
