The answer is D. Ammonia is a weak electrolyte and a weak base. Ammonia produces ions when dissolving but remains predominantly as molecules that are not ionized. This is what makes it a weak electrolyte. Ammonia also does not fully ionize in a solution. This is what makes is a weak base.
Answer:
Sample C has the highest density
Explanation:
Step 1: data given
Sample A has a mass of 224.96 grams
Sample B has a mass of 0.55632 lbs = 252.3425 grams
Sample C has a mass of 0.30648 kg = 306.48 grams
The volume is for all the sample equal
Step 2: Calculate density
We suppose the volume is 1000 mL
Density = mass / volume
Density sample A = 224.96 grams / 1000 mL = 0.22496 g/mL
Density sample B = 252.3425 grams / 1000 mL = 0.2523425 g/mL
Density sample C = 306.48 grams / 1000 mL = 0.30648 g/mL
Sample C has the highest density
Answer:
C, increases/decreases
Explanation:
As you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus.
Answer:
they're close to filling their outer shell, fulfilling the octet rule
