Answer:
<h2>6.41 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual density = 7.80 g/cm³
error = 7.30 - 7.80 = 0.5
We have
We have the final answer as
<h3>6.41 %</h3>
Hope this helps you
Answer:
The answer is option 3.
Explanation:
Option 3 shows a balanced equation.
Answer:
Explanation:
A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.

Explanation:
<u>Step 1: Define</u>
0.200 mol H₂S
<u>Step 2: Identify Conversions</u>
Molar Mass of H - 1.01 g/mol
Molar Mass of S - 32.07 g/mol
Molar Mass of H₂S - 2(1.01) + 32.07 = 34.09 g/mol
<u>Step 3: Convert</u>
- Set up:
- Multiply:
<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs.</em>
6.818 g H₂S ≈ 6.82 g H₂S
thx but it's actually 143
