in the right side of the periodic table . It is group 18 called nobel gas or group This group has all element in stable form each has 8 electron in outermost orbit they are non reactive

Answer:

Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level.

Elements: Argon

Which of the following pieces of laboratory glassware should be used to most accurately measure out a 25.00 ml sample of a solut
wel

Answer:

The correct answer is 25 mL graduated cylinder (it should be used in all the cases)

Explanation:

In order to measure 25.00 ml sample of a solution it should be used a 25 mL graduated cylinder, as it is previously and properly calibrated. The other laboratory glassware, beaker and erlenmeyer, have graduations which are approximate, so they are used when exact volumes are not needed.

ii) graduated cylinder has the least uncertainly. It is more accurate than a beaker or erlenmeyer (to within 1%)

iii) A 25 mL graduated cylinder should be used because it is the most accurate lab glassware (between those were mentioned: beaker, erlenmeyer).

What effect does heating a solid to a hightemperature have have on its crystal lattice ??
kotegsom [21]

Arrangement of atoms or group of atoms in a three dimensional ordered pattern in a crystal is said to be a crystalline lattice. They are arranged in a specific pattern with high symmetry. The heating of the crystal at high temperature will result in the increase of vibrational kinetic energy of the atoms in the crystal and this will result in the breaking of lattice apart and due to the breaking of lattice apart the ions will flow freely.

Thus, the heating of a solid at high temperature will lead to the lattice breaks apart and ions will flow freely.

Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed leave it blank. If no reaction occurs leav
Andrei [34K]

Answer:

ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)

Explanation:

First, we will write the molecular equation, since it is easier to balance.

2 HBr(aq) + ZnS(s) ⇄ H₂S(aq) + ZnBr₂(aq)

In the full ionic equation we include all ions and molecular species.

2 H⁺(aq) + 2 Br⁻(aq) + ZnS(s) ⇄ 2 H⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + 2 Br⁻(aq)

In the net ionic equation we include only the ions that participate in the reaction and the molecular species.

ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
