Answer:
It’s D
Explanation:
It’s an alloy so it is not pure. If you take a small sample and analyze it, the mixture will be similar throughout. Think of Gatorade as a homogeneous mixture because it is the same concentration of all ingredients throughout. Think of pizza for heterogeneous mixtures.

Answer: Chemical
<u>Explanation:</u>
When paper is burned, it creates a chemical change.
From our knowledge of periodic trends, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.
<h3>Periodic trends</h3>
The periodic trends are those properties that increase or decrease down the group or across the period. These periodic trends include;
- Ionization energy
- Electron affinity
- Atomic radius
- Ionic radius etc
As more shell are added down the group in group 14, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.
