Answer:
Observe the other planet throughout the year. Look at the environment when the season changes to see what changes in the environment.
Answer:
Viscosity increases with stronger intermolecular forces
Step-by-step explanation:
<em>Viscosity</em> is the resistance of a liquid to flow.
A liquid can flow easily only if the molecules can move past each other with little resistance.
If there are strong intermolecular attractive forces among molecules, it is more difficult for them to move past each other.
For example, the molecules in molasses have strong attractive forces, so it is quite viscous.
Answer:
0.375 grams are needed to make 25 mL solution.
Explanation:
Mass of 
cuprous nitrate required to make 1 l of solution = 15 g.
1 L = 1000 mL
Mass of cuprous nitrate required to make 1000 mL of solution = 15 g
Mass of cuprous nitrate required to make 1 mL of solution:
Mass of cuprous nitrate required to make 25 mL of solution:
0.375 grams are needed to make 25 mL solution.
