The law that the product of the pressure and the volume of one grammolecule of an ideal gas is equal to the product of the absolutetemperature of the gas and the universal gas <span>constant.</span>
Answer:
0.367M
Explanation:
Molarity refers to the molar concentration of a solution. It can be calculated using the formula below:
Molarity = n/V
Where;
n = number of moles (mol)
V = volume (L)
According to the given information in this question;
n = 0.55 mole
V = 1.50 L
Molarity = 0.55/1.50
Molarity = 0.367M

Answer: Dip the same brush into the polymer powder and slightly rotate it
Explanation:
After removing the excess, dipping the same brush into the polymer powder and rotating it slightly would form a paste solution that can be used for enhancement, e.g nail enhancement called sculptured nails.
Answer: The equilibrium will shift to the left.
Explanation:
If sodium acetate is added to acetic acid, the dissociation of the acetic acid is suppressed. The equilibrium position shifts to the left and the hydrogen ion concentration decreases due to decreased ionization of the acid. This common ion solution becomes less acidic than pure acetic acid.
This is so because of common ion effect. The acetate ion already present from the dissociation of acetic acid is also present in the sodium acetate. The presence of a common ion usually shifts the equilibrium position towards the left.
NaCH3CO2 (s) → Na + (aq) + CH3CO2 −(aq)
CH3CO2H(aq) ⇌ H +(aq) + CH3CO 2− (aq)
