Answer:
0.03697 mol Al₂(SO₄)₃
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
12.65 g Al₂(SO₄)₃
<u>Step 2: Identify Conversions</u>
Molar Mass of Al - 26.98 g/mol
Molar Mass of S - 32.07 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Al₂(SO₄)₃ - 2(26.98) + 3(32.07) + 12(16.00) = 342.17 g/mol
<u>Step 3: Convert</u>
<u />
= 0.03697 mol Al₂(SO₄)₃
<u>Step 4: Check</u>
<em>We are given 4 sig figs. Follow sig fig rules and round.</em>
We already have 4 sig figs in the final answer, so no need to round.
Answer:
Explanation:
Noble gases occupy the last group of the periodic table
They have fully filled valence electron shell
What this means is that they have attained stability and thus do not take part in chemical bonding that usually invloves the transfer or sharing of electrons
Thus, noble gases are snobs because they do not partake in chemical bonding with atoms of other elements or atoms of theirselves
The flow rate of water differs from honey due to the texture and thickness of the product. Honey’s thickness doesn’t allow it to move as quickly as the water, therefore affecting the flow rate.
You never told us how old you are so how are we supposed to answer
I think the correct answer from the choices listed above would be the first option. The angle between the hydrogen atoms in water (H2O) is slightly less than expected for a tetrahedral shape. This is because of the extra electron repulsion from the lone pairs. Hope this helps.
