10 grams of cocaine helps chalk to grow and the mass was increase a way lot more
The Haber Process combines nitrogen from the air with hydrogen to form ammonia. The reaction is reversible and the production of ammonia is exothermic.
N2(g)+H2(g)⇌2NH3(g)
Answer:
D) both groups are equatorial.
Explanation:
To solve this question we can start by drawing the molecule in using the <u>structure of the hexagon</u>. In this structure, we have the methyl group on carbon 1 and the terbutyl group on carbon 3, additionally, if we have a cis structure both groups must have the same type of bond (in this case the wedge bond). (See figure 1)
When we write the <u>chair structure</u>, we must keep the same structure. That is, methyl must be on carbon 1 and terbutyl on carbon 3. Also, the cis configuration must be maintained. With this in mind, we can choose the <u>equatorial configuration</u> for methyl on carbon 1 (since the position equatorial is the one that has <u>less steric impediment and more stability</u>). If this is true for carbon 1, we must place the terbutyl group on carbon 3 in the same configuration (i.e. cis). Therefore, on carbon 3 we must place the tert-butyl down on carbon 3, that is, in the <u>equatorial position</u>. (See figure 1).
Therefore, in the chair-like structure, both groups must be in an equatorial position.

Answer:
Its density decreases
Its volume increases
Explanation:
You notice that ice floats on water, this means that its density is less. The mass remains the same because you did not add or remove anything. But what causes the density to decrease then? For density to change, there needs to be a change in either the volume or the mass of the object. Density is calculate by mass/volume. Since the mass did not change, the volume must have. So in this case, the volume increases. Hence, this is what causes it to be less dense. :)
