What is the molarity of a solution that contains 80.0 grams of NaOH dissolved in 500 mL of solution? Student prepares a solution by dissolving 3.72 g of NaOH in enough water to make 300.
Answer: Option (B) is the correct answer.
Explanation:
When the book was at the shelf, it had only potential energy as potential energy is the energy possessed due to the position of an object.
Therefore, when the book falls from the book shelf it gains kinetic energy as kinetic energy is the energy possessed due to the motion of an object.
Thus, when the books is falling from the top shelf then the motion of book increases therefore, we can conclude that the potential energy decreases as kinetic energy increases.
It will sink because water has a density of 1. and 1.1 is greater than 1 which means that the object is denser than the water so it will cause it to sink
Answer:
The second option
Explanation:
The process of elimiation.
1. We know liquids dont have a definite shape, they will morph into whatever enviroment theyre in
3. Solids dont expand based on what container theyre in, they either dont fit or they do
4. We know that liquid expands, so we can also rule this one out.
Which leaves us with option 2 to be correct.
