Answer:
False
Explanation:
It becomes a heterogeneous mixture
Answer:
The answer to your question is below
Explanation:
1) 0.143g of Mg into atoms
- Look for the atomic number of Magnesium in the Periodic table
Atomic number = 24.31 g
-Use the Avogadro's number to find the number of atoms
24.31g ------------------- 6.023 x 10²³ atoms
0.143 g ----------------- x
x = (0.143 x 6.023 x 10²³) / 24.31
x = 8.613 x 10²² / 24.31
x = 3.54 x 10²¹ atoms
2) 0.101 kg of Ti into atoms
-Look for the atomic number of Titanium in the Periodic table
Atomic number = 47.87 g
-Use the Avogadro's number to find the number of atoms
47.87 g --------------------- 6.023 x 10²³
101 g ---------------------- x
x = (101 x 6.023 x 10²³) / 47.87
x = 6.08x 10²⁵ / 47.87
x = 1.27 x 10²⁴ atoms
All the elements you listed share a common trait: they are synthetic, radioactive elements. These elements do not have a stable isotope, so for a radioactive element, its most stable isotope's atomic mass will be listed in parentheses.
One such example would be plutonium. This element has 6 different isotopes with differing half-lives. The most stable isotope for plutonium is plutonium-244, with a half-life of around 80 million years. Therefore, the atomic mass listed for plutonium will be (244).
