Answer:
I think its a homogeneous mixture (pls correct me if im wrong)
Explanation:
It is a homogeneous mixture because its an alloy made of gold, silver, copper, and other metals that are melted together. A homogeneous mixture is composed of a uniform composition of particles.
Answer:
see below
Explanation:
1. Yes, it is possible because they have similar intensive properties.
2. homogeneous mixture
3. Due to the repulsion between electrons, valence electrons will be arranged as far apart from each other as possible.
4. Neutral atoms of lead must have 82 protons. Ions must have 82 protons, as well.
5. Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.
6. A covalent bond would form because the electron would be shared so both hydrogens have a full, stable shell.
7. K and Cl
8. Polar sugar molecules dissolve in water, which is polar.
9. High temperatures mean more kinetic energy, which keeps sodium and chlorine ions from combining, which increases solubility.
10. It accepts protons and only partially dissociates in water.
11. PH3 is a stronger acid than NH3.
12. The scientist is investigating Charles’s law, which shows that temperature and volume are directly proportional.
13. Fr
14. Student B, because of the law of conservation of matter.
15. The atoms have the same electronegativity.
16. bromine (Br)
17. BO3 would have because the electronegativity difference between boron and oxygen is greater than that between boron and hydrogen.
18. 6H2O + 6CO2 → C6H12O6 + 6O2
19. +2
20. 0.12 M
21. Tungsten (W) changes oxidation numbers from +6 to zero, so it undergoes reduction.
22. It has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.
23. Heat each substance in liquid form to its boiling point in environments with the same atmospheric pressure. Measure the temperature of each substance.
24. Water has a higher boiling point because it has more hydrogen bonds.
25. The student should perform multiple trials of the same experiment, then take the average of all of the results.
26. Some liquids might have melting points that are far lower than room temperature.
