Answer:
True
Explanation:
Reason being there are 3 systems even in the open system the heat and matter goes in and out , the closed system the heat goes in and out as well and in the isolated system it stays in
Answer:
The correct answer is:
2.6 m3 (B)
Explanation:
SF unit stands for Stowage factor unit. Stowage factor is the volume occupied by one unit of mass (weight) when stowed in cargo space. SF expresses the unit in cubic meters (m³) or cubic feet. SF is a unit of measurement that indicates how much space (volume) a particular unit of cargo occupies in a ship's cargo compartment
Answer:
Their energes can have any values
Explanation:
I think the removal of the cell membrane
Explanation:
Question 1
Rate constant = 3.50×10−3 s−1
Initial Concentration [A]o = 0.450 M
Final concentration [A] = ?
time = 19 minutes = 1140 s (upon conversion to seconds)
Integrated rate law for a first order reaction is given as;
ln[A] = ln[A]o - kt
ln[A] = ln (0.450) - (3.50×10−3)1140
ln[A] = -0.799 - 3.99
ln[A] = -4.789
[A] = 0.0083M
Question 2
Rate constant, k = 3.50×10−4 M/s
time = 65 s
Final Concentration [A] = 3.50×10−2 M
Initial Concentration [A]o = ?
Integrated rate law for a first order reaction is given as;
[A] = [A]o - kt
[A]o = [A] + kt
[A]o = 3.50×10−2 + (3.50×10−4) * 65
[A]o = 3.50×10−2 + 0.02275
[A]o = 0.05775 M
