To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock
solution, V1 is the volume of the stock solution, M2 is the concentration of
the new solution and V2 is its volume.
1.75 M x V1 = 0.100 M x 2.0 L
V1 = -.11 L
Answer
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds
Explanation:
Answer:
I think it would be b. The octet rule states that transition metal group elements tend to react so that they attain a noble gas electron configuration.
Answer:
The answer is "1".
Explanation:
It is the lone pairs at, which the central atom provides the molecular and the polarity. It is only for substances with just a central atom, for which the molecules with only one central atom and only one of the solitary paired were required, that's why in this question the "1" is the correct answer.
