Answer:
Explanation:
depending on the activity series there will probably be a single replacement reaction possibly heat or color change and the copper precipitate out of solution
Answer:
<h2>isotope is a variants of a particular chemical element which differ in neutron number, and consequently in nucleon number.All isotopes of a given element have the same number of protons but different number of neutrons in each atom.</h2>
<h2>The 2 important physical properties of isotope is</h2>
<h2>1.<u>M</u><u>e</u><u>l</u><u>t</u><u>i</u><u>n</u><u>g</u><u> </u><u>Points</u></h2><h2>
2.<u>B</u><u>o</u><u>i</u><u>l</u><u>i</u><u>n</u><u>g</u><u> </u><u>Points</u></h2>
Step 1
The osmotic pressure is calculated as follows:

-------------
Step 2
<em>Information provided:</em>
The mass of solute = 13.6 g
Volume of solution = 251 mL
Absolute temperature = T = 298 K
The molar mass of solute = M = 354.5 g/mol
-------------
Step 3
Procedure:
1 L = 1000 mL => Volume = 251 mL x (1 L/1000 mL) = 0.251 L
---
C = moles of solute/volume of solution (L)
C = mass of solute/(molar mass x Volume (L))
C = 13.6 g/(354.5 g/mol x 0.251 L)
C = 0.153 mol/L
---
π = C x R x T
π = 0.153 mol/L x 0.082 atm L/mol K x 298 K
π = 3.74 atm
Answer: π = 3.74 atm
