Answer:
Explanation:
Hello there!
In this case, since the molality of a solution is calculated by dividing moles of solute by kilograms of solvent, it turns out firstly necessary for us to calculate the moles of methyl alcohol in 75.0 grams as shown below:
Then, the kilograms of water, 0.600 kg, and finally, the resulting molality:
Regards!
Solubility product constants are values to describe the saturation of ionic compounds with low solubility. A saturated solution is when there is a dynamic equilibrium between the solute dissolved, the dissociated ions, the undissolved and the compound. The general equation is MxAy(s) --> x My+(aq) + y Ax-(aq) where the solubility product constant expression is Kc = [My+]x[Ax-]y.
Is this a check all that apply?
I believe it's Ammonium chloride
In any compound there are two types of ions are present, cations and anions. Cations are positively charged ions and formed by losing electrons and anions are formed by gaining electrons and are negatively charged ions.
So, in K₂HPO₄, there are positive charged and negative charged ions are present. so there is K⁺ ion and HPO₄⁻² ion is present in K₂HPO₄
