Which of the four solutions is the best buffer against addition of acid or base?
Vera_Pavlovna [14]

b. Na2HPO4 + NaH2PO4.

A <em>buffer </em>is a solution of a weak acid and its conjugate base. The weak acid is H2PO4^(-) and its conjugate base is HPO4^(2-).

All the other options are incorrect because they consist of only a single component.

Why is an alpha particle written as a helium (He) nucleus?
Nat2105 [25]
Well, an alpha particle is made up of four subatomic particles: two protons, and two neutrons. Helium has two protons and two neutrons, meaning that alpha particles are, in fact, similar to helium nuclei. That's why they are written as 2^4 He

Besides hydrogen and oxygen what is required to produce the chemical reaction that yields water
timurjin [86]
Hey there! Hello!

In order for water to be formed, or for any reaction to occur, there needs to be something that splits the current bonds of hydrogen and oxygen up. In this case, some sort of activation energy is required. 

Hydrogen and oxygen are not found as single molecules in nature. They're found as 2 molecules linked together, as H2 and O2. An activation energy, such as heat, or some sort of catalyst needs to be used in order to split the two molecules up and make them link with one another. 

What happens afterwards is a chemical reaction that involves the valence electrons of oxygen (which has 6 on the outermost shell) and hydrogen (which has two on the outermost shell). The oxygen wants to have an octet (8 valence electrons) total, so it shares with the hydrogen, which is already satisfied with it's two valence electrons (according to the nature of hydrogen). 

But because there has to be a total of four molecules involved, two molecules of water are going to be produced as a result. 

2H+2O=2H20

Hope this helped you out! Feel free to ask me any additional questions if you need further clarification. :-)
