Answer:
It partially ionizes
Explanation:
Higher tier) Weak acids only partially ionise in water. Only a small fraction of their molecules break into hydrogen ions when added to water.
Answer:
D. 5
Explanation:
The coefficient will almost always be the whole number in front of the variable.
example
5(x)= 7
The coefficient would be 5.
We have that you can you prepare 450 ml of 1 X buffer A by adding 45ml of 10X buffer A with 405ml(450-45) of water
From the question we are told
If you have 100 ml of 10X Buffer A, how could you prepare 450 ml of 1 X buffer A
Generally the equation for the Concentration Volume relationship is mathematically given as
Therefore
You can you prepare 450 ml of 1 X buffer A by adding 45ml of 10X buffer A with 405ml(450-45) of water

A lemon juice cleans a penny. I believe this to be the answer because the lemon cleans the penny but no molecules change
Answer:
has 4 electrons in its valence shell.
Explanation:
Silicon has 14 protons, so its neutral atom has also 14 electrons, thus, the electron distribution following the Linus Pauling's diagram is:
1s² 2s²2p⁶ 3s²3p²
Thus, it has 4 electrons in its valence shell (3), likely carbon. So, silicon would have some of the properties of carbon, such as form 4 bonds, and the structure would be similar.
