Answer: Block # 1 , Block # 4 and
Block # 5 will sink.
Block # 2 and 3 will float.
Explanation: The density of water is equal to 1 g/mL. Any density that is less than the density of water will float. Objects with higher density compared to water will eventually sink.
There is acetone, xylene, and toluene in spray paint
Answer:
Chemical reaction are irreversible. Some of the example of chemical reaction are cooking, rusting, and burning. During a chemical reaction, the composition of substances changes and the particles rearrange to form a new substance. The new substance formed after chemical reaction of substance has different physical and chemical properties.
When a chemical reaction occur, the atoms or molecules of the substances change its physical and chemical properties such as while cooking of vegetable, the molecules of vegetable undergo changes in their properties and form a new substance which is different from the earlier.
The shells further away from the nucleus are LARGER and can hold MORE electrons
Answer:
We have the final answer as
<h2>0.68 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 40.8 g
volume = 60 mL
The density is

We have the final answer as
<h3>0.68 g/mL</h3>
