Answer:
8.29 mL
Explanation:
Density of acetone in g/mL = 0.791 g/ml
Dimensional analysis: 6.56 g x (1 mL/0.791 g) = 8.29 mL
If you heat a liquid like water up even more (like if you put it in a pot on the stove), then the molecules will move around so fast that they can't even hold on to each other at all. When this happens, all of the molecules go flying apart and become a gas (like when you boil water to make steam).
So you basically need to heat the water to turn it into gas.
Erosion can be created from all of them (All of the above)
Answer:
Refinement
Explanation:
The 3R's policy was fundamentally introduced to safeguard the animals from harsh experiments which could change their mental and physical abilities and lead to their extinction one day.
The principles of 3R's (Replacement , Reduction and Refinement) were developed long time ago. It is an strategy to perform more Humane animal research.
These are defined as,
Replacement is a method to avoid or replace the uses of animals.
Reduction is a method to minimize the number of animals used every experiment.
Refinement is a method of minimizing animal suffering and improving welfare.
