Answer:
Neutrons and Protons, Electrons
Explanation:
Neutrons and protons are in the inside as electrons orbit around it in a circular pattern
Answer:
24 atm is the total pressure exerted by the gases
Explanation:
We propose this situation:
In a vessel, we have 4 gases (for example, hydrogen, Xe, methane and chlorine)
Each of the gases has the same pressure:
6 atm → hydrogen
6 atm → xenon
6 atm → methane
6 atm → chlorine
To determine the total pressure, we sum all of them:
Partial pressure H₂ + Partial pressure Xe + Partial pressure CH₄ + Partial pressure Cl₂ = Total P
6 atm + 6 atm + 6 atm + 6 atm = 24atm
Explanation:
Sulfur has 6 valence electron
Valence electron shows group( in column)
If It takes 60mL of 0.20M of sodium hydroxide (NaOH) to neutralize 25 mL of carbonic acid (
), then the concentration of the carbonic acid is 0.24M
The reaction between NaOH solution and is written below
Volume of NaOH, 
= 60 ml
Volume of , 
Molarity of , 
Molarity of NaOH, 
Number of moles of , 
Number of moles of NaOH, 
The mathematical equation for neutralization reaction is:
Substitute 
, , , = 60ml, and into the equation above in order to solve for 
Therefore, the concentration of the carbonic acid is 0.24M
