  1. The element Sodium (Na) has a low electronegativity of the following elements.
  2. The element Beryllium (Be) has the least metallic character.
  3. The element Sodium (Na) has the largest atom.

<u>Explanation:</u>

  • Sodium (Na) which is a delicate, shimmering white, profoundly responsive soluble base metal loses an electron to a chlorine iota since it has seven electrons in its valence shell.
  • It needs one more electron to turn into a steady molecule. It has the most reduced electronegativity of the given components.
  • Beryllium (Be) is a light, silver-gray, relatively soft metal that is strong but brittle has the least metallic character of the given elements.
  • Since from left to right in a period, Metallic character decreases while nonmetallic character increases from top to bottom.
  • Sodium(Na) is the largest atom among the given elements since Atomic size decreases across a period from left to right and increases from top to bottom.

kogti [31]

Answer:

1) volumetric

2) graduated

3) volumetric

Explanation:

A volumetric glassware is a glassware that is marked at a particular point. A typical example of a volumetric glassware is the volumetric flask. A volumetric glassware is capable of measuring only a specific volume of a liquid.

On the other hand, graduated glassware can measure a range of volumes of liquid. However, a volumetric glassware is still required where a high degree of accuracy is important.

ubstance A is a nonpolar liquid and has only dispersion forces among its constituent particles. Substance B is also a nonpolar l
LenaWriter [7]

Answer:

Their particles exhibit the same type of intermolecular interaction

Explanation:

In chemistry, we commonly say that 'like dissolves like'. This implies that polar solvents dissolves polar solutes while nonpolar solvents dissolve nonpolar solutes.

This phenomenon of 'like dissolves like' is possible because, the dissolution of one substance in another involves intermolecular interaction between the solute and solvent molecules.

If the molecules of solute and solvent are both nonpolar and have about the same magnitude of intermolecular (dispersion) forces, interaction between the both molecules is significant hence the solute dissolves completely in the solvent.

mariarad [96]

Answer:

3.82 × 10 ^-23 g

Explanation:

6.02 x 10^23atoms = 1 mole of sodium

1 atom = 1/(6.02 x 10^23) mole

mass = mole × molar mass

= 1/(6.02 x 10^23) × 23

= 3.82 × 10 ^-23 g
