Proton: positive- mass equal to neutron
Electron: negative- mass 1/1840 mass of proton
Neutron: no charge- same mass as proton
I’m sorry but I’m not good at chemistry, so I will not be able to help you.
Answer:
393.1 KPa
Explanation:
Now we have to use the general gas equation;
P1V1/T1 = P2V2/T2
P1= initial pressure of the gas= 1.00atm
V1 = initial volume= 700.0 ml
T1= initial temperature= 0.0°C +273= 273K
V2= final volume= 200.0 ml
T2= final temperature =30.0°C +273= 303 K
P2= final pressure =????
Therefore;
P2= P1V1T2/ V2T1
P2= 1.00 × 700.0 × 303/ 200.0 × 273
P2= 3.88 atm
But
1 atm = 101.325 kilopascals
Therefore 3.88 atm = 3.88 × 101.325 kilopascals = 393.1 KPa
Answer : The number of moles of sulfur needed to oxidize will be, 3 moles
Solution : Given,
Moles of zinc = 3 moles
The balanced reaction will be,
By the stoichiometry, 1 mole of 
ion react with the 1 mole of 
to give 1 mole of zinc sulfide.
From the balanced reaction, we conclude that
As, 1 mole of zinc react with 1 mole of sulfur
So, 3 moles if zinc react with 3 moles of sulfur
Hence, the number of moles of sulfur needed to oxidize will be, 3 moles
Answer:
C6H12O6(s) -> C6H12O6(aq)
Explanation:
Glucose, C6H12O6, is a nonelectrolyte, so it will dissolve in water but will not dissociate at all. Strong electrolytes dissociate completely, weak electrolytes dissociate partially, and nonelectrolytes do not dissociate in water.
