Answer:
3
Explanation:
You have to mutiply the silver reaction by 3 in order to substract the electrons
<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
We are given:
A weak acid that is hypochlorous acid (HClO) and basic salt that is sodium hypochlorite (NaClO)
When a strong base is added to the buffer, the hydroxide ion will be neutralized by hydrogen ions from the acid.
So, the buffer component that neutralizes the additional hydroxide ions in the solution is HClO
The chemical equation for the neutralization of hydroxide ion with acid follows:
Hence, the balanced chemical equation is written below.
PbO2
You have to take the mass of lead in the problem, and divide by the molar mass.
When you do the same with oxygen, you get a number about twice as large as when you divide the mass of lead by the molar mass of lead. This means that the simplest formula would be PbO2
Electron cloud is the region around the nucleus in an atom where we can locate an electron.
The concept of electron cloud model was introduced by the Schrodinger and Heisenberg. According to this model, it would be difficult to know the position of the electrons in an atom and they are not particles that orbit around the nucleus. We can only expect the electrons to be present in specific areas called the electron clouds around the nucleus. It is the quantum mechanical model that used the concept of electron clouds. According to the model, the electron cloud or an orbital is a space around the nucleus in an atom where the probability of finding an electron is 90%. It explains that electrons show wave nature. It is difficult to determine the exact position and momentum of an electron in an atom.
Answer:
The responding variable of this experement is the outcome and that would be that the one in lemon juice responded and the one in water didn't (the other one is the control). Thus the responding varible is the one in lemon juice.
