When ph decreases the hydrogen ion concentration increases because ph = - log (H)
Likewise, the other way around is true (when hydrogen ion concentration increases, pH decreases).
1.5x10^24 over 1 multiplied by 1 mol over 342g C12H22O11 multiplied by 6.02x10^23 over 1 mol
Multiply all across the top then divide by bottom
2.64 Mol
Answer: The pressure of the gas is 0.34 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = ?
V = Volume of gas = 605 ml = 0.605 L (1L=1000ml)
n = number of moles = 0.00803
R = gas constant =
T =temperature =
The pressure of the gas is 0.34 atm
9. all you have to do find the atomic mass of each atom in the periodic table.
Na is 23.0
O= 16.0
molecular mass of Na2O= 2x23.0 + 16.0= 62.0 g/mol
10. this is the description of an acid
A cation is an ion that has a positive charge, while an anion is an ion with a negative charge.
Your answer would be A) Li+
Li+ is the cation listed, and Cl- is the anion listed.
If NaCl was put into a solution, it would dissociate and the ions present would be Na+ and Cl-.
