Hello there! We don't consider Ice usable, so the answer would be option D) ice.
Hope this helps!
Answer:
Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.

Answer:
Titration
Explanation:
Titration is a method to determine the concentration of an unknown solution by using a known concentration solution.
The known concentration solution (titrant) - NaOH 1.0 M is added through the burette to the flask containing unknown concentration solution (analyte) - HCl. For example, if the volume of NaOH used to neutralise 20 ml of HCl is 10 ml, the concentration of HCl is 0.5M. To elaborate,
Equation: NaOH + HCl → NaCl + H2O
moles of NaOH = Concentration (mol/L) x Volume (L) = 1.0 x 0.01 = 0.01 mol
moles of NaOH = moles of HCl = 0.01 mol
⟹ concentration of HCl = moles / Volume = 0.01/0.02 = 0.5M.
What are the mol ratios? if you’re just comparing with the mass (which i doubt so since most limiting questions require u to compare the mols)
but if u are, the limiting would be nitrogen since it’s lesser than calcium mass
Answer:
The mole is the SI unit for amount of a substance.
Explanation:
Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.
