Answer:
This is apparent charge, like water molecule is neutral having zero net charge
Explanation:
Simple and understood
Answer:
80.7 L
Step-by-step explanation:
This looks like a case where we can use the Ideal Gas Law to calculate the volume.
pV = nRT Divide both sides by p
V = (nRT)/p
=====
Data:
n = 5.00 mol
R = 0.082 06 L·atm·K⁻¹mol⁻¹
T = (120 +273.15) K = 393.15K
p = 1520 mmHg × 1 atm/760 mmHg = 2.00 atm
=====
Calculation:
V = (5.00 × 0.082 06 × 393.15)/2.00
V = 161.3/2.00
V = 80.7 L
Answer:
1. watershed
2. point
3. nonpoint
Explanation:
The land that supplies water to a river system is called a watershed
Pollution from a single, identifiable source is called point
Pollution that is difficult to link to a particular origin is called nonpoint
Answer:
A. a rotten potato gives all of bad smell
Explanation:
B,C,D are all physical changes because we can reverse them back.we can cool the water back to make ice. if the wind passes again we can randomly get the same cloud shape in c. and in d we can make that statue again. but in A can we reverse the rotting process ? ( the enzyme reaction) no we cant because it is a chemical reaction it gives a bad smell because of the chemical changes occuring in it.
hope this helps
