Hello!
The particles in a<span> gas </span>have<span> the most energy </span>and are<span> free to move around </span>and<span> so spread out rapidly. Gases do </span>not have a<span> definite </span>shape<span> or volume </span>and expand to fill<span> the entire</span>container<span>. Thus, as the temperature of matter increases, </span>its<span> density decreases.

Answer:
2M
Explanation:
Given parameters:
Number of moles of FeCl₃ = 0.3 moles
Volume of water = 150mL
Unknown:
Molarity of solution = ?
Solution:
The molarity of a solution is the number of moles of solutes in a given solution. It is one of the ways of expressing concentration. The unit is always M i.e mol/dm³.
Molarity =
Express the volume in dm³;
150mL gives 0.15dm³
Molarity =
= 2M
Answer:
No because there is no oxygen in the package
Answer:
Here are some disadvantages
Explanation:
Hard water does not pose a health threat.

Answer:
Subtract them.
Explanation:
''''"Since all number in scientific notation have base 10, we can always multiply them and divide them. To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents."""""
I was actually learned about this in school just found an source.
