An electron is smaller than a proton. An electron has the opposite charge of a proton. An electron is outside the nucleus, while a proton is part of the nucleus.
If the ion is a cation, it has a positive charge because it LOST electrons. If its an anion, then it has a negative electron because it GAINED electrons.
Answer:
2.73 is the equilibrium constant for the dissociation of gas at 840 degree Celsius.
Explanation:
Initial
0.600 atm 0
Equilibrium
(0.600 atm - p) 2p
Total pressure at equilibrium = P = 0.984 atm
P= 0.600 atm - p)+2p=0.984 atm
p = 0.384 atm
Partial pressure of the gas , = (0.600 atm - 0.384 atm)=0.216 atm
Partial pressure of the gas, = 2(0.384 atm)=0.768 atm
2.73 is the equilibrium constant for the dissociation of gas at 840 degree Celsius.
PH is the concentration of Hydrogen ions (shown as [H+]) in a solution. The scale for pH is 0-14, with 0 being very high acidity and 14 being low acidity (basic). The scale is a logarithmic scale, so this means that each number is 10 times stronger than the number that precedes it.
The pH of the tomato juice is 4, which is more acidic than the black coffee with a pH of 5. Since there is a difference of one number between the two (scale of 1), then this tells us that the concentration of Hydrogen ions in the tomato juice is ten times GREATER than the [H+] of the black coffee.
Answer:
partial negative is O(oxygen) and partial positive is (H) Hydrogens
Explanation:
Because the molecule has covalent bonds, all charges are partial.
Partial negative is O(oxygen) and partial positive is (H) Hydrogens.
