Think about something very important to you that you would like to accomplish 10 years from now. Write a short-term, medium-term
Vinil7 [7]

Answer:

Goal: to propose a strategy to mitigate carcinogenic dyes present in wastewater.

Explanation:

Hello,

Short-term: Based on my interest about the treatment of carcinogenic effluents in the dyes industry, I'm planning to develop a research about how fast microorganisms could decompose such dyes in order to provide pure water-composed outlet streams. For now, I can suggest that they could work as long as they grow in a simulated dye-rich environment.

Medium-term: In such a way, the subsequent plan is to set up the reaction scheme and the reactor design stage for this bioprocess by running several test in order to collect the experimental data to back up the proposed mathematical model.

Long-term: Finally, the start-up of the whole process starting by the inlets and operation conditions, continuing by the innermost sub processes to decompose the dye and the subsequent adaptation of the outlet streams to produce drinkable water, will be carried out in order to help the environment and living things that are highly affected by those dyes.

Best regards.

Doing an Endothermic reaction, what happens to energy in relation to the surroundings?
natali 33 [55]

Answer:

Doing an Endothermic reaction, energy is absorbed from surroundings

Explanation:

Endothermic reactions:

The type of reactions in which energy is absorbed are called endothermic reactions.

In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.

For example:

C + H₂O   →  CO  + H₂

ΔH = +131 kj/mol

it can be written as,

C +  H₂O  + 131 kj/mol  →  CO  + H₂

we can see that 131 kj/mol energy is taken by the reactants. So energy is absorbed from surrounding.

Exothermic reaction:

The type of reactions in which energy is released are called exothermic reactions.

In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.

For example:

Chemical equation:

C + O₂   →  CO₂

ΔH = -393 Kj/mol

it can be written as,

C + O₂   →  CO₂ + 393 Kj/mol

WILL BE MARKED THE BRILLIENST what is density?
Naddik [55]

Density is how much matter is packed into a certain substance. So it's a measure of how tightly packed particles are. If particles are tightly packed, they will be more dense and if they're loosely packed they will be less dense. Normally, something solid will be more dense than something liquid. So density is how much matter there is a certain amount of space or volume.
