Answer:
when something is boiling. the temperature increases quickly so B and D are eliminated. So its either A or C. My guess is A
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:
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
Explanation:
The degree of unsaturation is calculated through the following formula:
2n + 2 - H / 2
n = Total number of hydrogen in given compound
There are six hydrogen in given compound, now we will calculate the degree of unsaturation by putting the value of n= 6
(2(6) + 2 - 6 )/ 2
(12+ 2 - 6) / 2
(14 - 6) /2
8 / 2 = 4
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
The given compound is benzene and degree of unsaturation is 4. Three double bond and one ring.
When a nucleus emits a positron, its atomic number is lowered by one but its mass number stays the same.
