Answer: 4 hydrogens
Explanation:
This is what the structure will look like C=C. Remember that it's important that all structures have a complete octet. As it looks right now each carbon is sharing 4 valence electrons so each needs 2 more bonds to hydrogen complete its octet.
No reaction will occur because magnesium is more reactive than zinc. If you did the reverse ( magnesium particles in zinc sulphate solution) than a reaction will occur in which the zinc will be displaced from solution.
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.

Climax community is the answer i believe
When a solid is added to a liquid, there exists a possibility that it will get dissolved in the solid. However, this depends on a lot of factors, like the temperature of the substances, the volume of the liquid, and the amount and nature of the solid to be dissolved.
