Answer:
B the system is unaffected
Answer:
1.28 mol Cu(OH)₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
125 g Cu(OH)₂
<u>Step 2: Identify Conversions</u>
Molar Mass of Cu - 63.55 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H - 1.01 g/mol
Molar Mass of Cu(OH)₂ - 63.55 + 2(16.00) + 2(1.01) = 97.57 g/mol
<u>Step 3: Convert</u>
= 1.28113 mol Cu(OH)₂
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
1.28113 mol Cu(OH)₂ ≈ 1.28 mol Cu(OH)₂
Answer:
Answer is A: a uniform mixture that can’t be separated
Explanation:
To solve this we assume
that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
T1 / V1 = T2 / V2
T2 = T1 x V2 / V1
T2 = 25 x 3 / 2
<span>T2 = 37.5 degrees Celsius</span>
