Answer: Dang I wish I wasn't on a school chrome, that way I can see the photo without it getting blocked *cries*
Explanation:
Molarity is defined as the number of moles in 1 L of solution
number of moles of sodium acetate is - 8.56 g / 82.03 g/mol = 0.104 mol
number of acetate moles in 750.0 mL - 0.104 mol
then number of acetate moles in 1000 mL - 0.104 mol / 0.7500 L = 0.139 mol/L
molarity of sodium acetate is 0.139 M
Answer:
n of krypton = 1.23 mol.
The no. of moles will not be changed, if the gas is either argon or krypton.
Explanation:
- The no. of moles of a gas (n) can be calculated by the general gas law of ideal gases: <em>PV = nRT</em>,
Where, P is the pressure of the gas in atm (P = 6.0 atm).
V is the volume of the gas container in L (V = 5.0 L).
n is the no. of moles of the gas.
R is the general gas constant (R = 0.082 L.atm/mol.K).
T is the temperature of the gas in K (T = 25.0°C + 273 = 298.0 K).
<em>∴ n = PV/RT </em>= (6.0 atm)(5.0 L)/(0.082 L.atm/mol.K)(298.0 K) = 1.228 mol = <em>1.23 mol.</em>
The no. of moles will not be changed, if the gas is either argon or krypton because it does not depend on the type of the gas.
Answer:
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant
, R = 0.082057 L atm.mol⁻¹K⁻¹
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Δn = (0)-(2+1) = -3
Thus, Kp is:
The melting and boiling point depend on the strength of the ihydrogen bonds. Hydrogen bonding will cause the higher the melting and boiling points because more energy is needed to break bonds between molecules.
Hydrogen bonds affect solubility in water, molecules with hydrogen bonds dissolve better in water.
