The Sun's location in the Milky Way, specifically in the Orion Arm, about 26,000 light years from the center.
Our Sun is located in the spiral part of the Milky Way galaxy. More specifically, it is found in one of the galaxy's spiral arms, known as the Orion Arm, or sometimes the Orion Spur.
The Milky Way consists of several components: the halo, bulge, disk, and spiral arms. The center, or bulge, contains older stars and a supermassive black hole. The halo contains globular clusters, while the disk contains stars of various ages, gas, dust, and the spiral arms, which have a higher density of gas and dust.
In contrast, our Sun is located about 26,000 light years from the center in the disk, residing in one of the spiral arms where star formation is quite active.

Answer:
1.) NiSO₄; 2.) Al₂O₃; 3.) Ca(ClO₃)₂; 4.) (NH₄)₃P; 5.) CuNO₃
Step-by-step explanation:
We can use the criss-cross method to work out the formulas. The steps are
- Write the symbols of the anion and cation.
- Criss-cross the numbers of the charges to become the subscripts of the other ion (as in the image).
- Write the formula with the new subscripts.
- Divide the subscripts by their highest common factor.
- Omit all subscripts that are 1.
If we use this method, the formula for the compound formed from Na⁺, SO₃²⁻ becomes Na₂SO₃.
1.) Ni²⁺ + SO₄²⁻ ⟶ Ni₂(SO₄)₂ ⟶ NiSO₄
2.) Al³⁺ + O²⁻ ⟶ Al₂O₃
3.) Ca²⁺ + ClO₃⁻ ⟶ Ca(ClO₃)₂
4.) NH₄⁺ + P³⁻ ⟶ (NH₄)₃P
5.) Cu⁺ + NO₃⁻ ⟶ CuNO₃
