The question above wants to assess your ability to create a model to represent a scientific concept. In that case, I can't create the model for you, but I'll show you how to create that template.

First, you must choose one of the topics presented in the question. I suggest that you choose the topic "Conservation of Masses," because of its simplicity, however you should choose the one you are most familiar with.

Next, you should research this topic and look at the factors that make it up.

After that, you can create your template as follows:

  • Use a software that has ready-made drawings, mainly geometric figures, for you to represent the elements that make up this topic.
  • Use these drawings to represent these elements, place titles that identify them, and add arrows, which direct the viewer's attention to understand the model.

You can see examples of "Conservation of Masses,"  models in the attached figure.

Glacial striations have been found in South America, South Africa, India, and Australia. What do these marks tell scientist?
zubka84 [21]
These mars can tell the scientist that there are still a lot of things that they can not discover. The glaciation can also tell us about the alignment of the earth and not just it can tell us about the climate. That is why it is really important for the scientist to study keenly in this kind of matters.

Hydrazine (N 2 H 4 )) a rocket fuel reacts with oxygen to form nitrogen gas and water vapor . The reaction is represented with t
Drupady [299]

The mass of hydrazine (N₂H₄) required to produce 96 g of water (H₂O) is 85.4 g (Option C)

<h3>Balanced equation </h3>

N₂H₄ + O₂ —> N₂ + 2H₂O

Molar mass of N₂H₄ = (2×14) + (4×1) = 32 g/mol

Mass of N₂H₄ from the balanced equation = 1 × 32 = 32 g

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY

From the balanced equation above,

36 g of H₂O were produced by 32 g of N₂H₄

<h3>How to determine the mass of N₂H₄</h3>

From the balanced equation above,

36 g of H₂O were produced by 32 g of N₂H₄

Therefore,

96 g of H₂O will be produced by = (96 × 32) / 36 = 85.4 g of N₂H₄

Thus, 85.4 g of N₂H₄ is needed for the reaction
