Answer:

  A, B, D, E

Explanation:

This titration involved adding measured amounts of an acid (HCl) to a base, and recording quantitative measurements of the resulting pH. The necessary equipment includes ...

  • an acid (specifically, HCl)
  • a base
  • a pH meter for quantitative measurements of pH
  • a device for precisely measuring the acid (a burette works for this)

We believe these requirements are consistent with choices A, B, D, E from the list given.

__

An "indicator" will typically change some obvious property (often, color) at a specific value of pH. It generally is not quantitative enough for the purpose of drawing the supplied graph. A pH meter is a better choice.

A bond in which one atom contributes both bonding electrons to a covalentbond
yKpoI14uk [10]
<h3>Answer:</h3>

A coordinate bond

<h3>Explanation:</h3>
  • A chemical bond is a force of attraction between two or more atoms of elements.
  • Covalent bond is a type of chemical bond that occurs between non-metal atoms.
  • It occurs as a result of sharing of electrons between the non-metal atoms.
  • Atoms involved in covalent bond formation may contribute equally to the bond formation or the electrons shared may come form one of the atoms.
  • When the electrons shared in a covalent bond are derived from one atom, then the covalent bond is known as a coordinate bond.

The maximum number of electrons in a single d subshell is:
son4ous [18]

10 electrons

Explanation:

The maximum number of electrons in a single d-subshell is 10 electrons.

The d-notation stands for an azimuthal quantum number or secondary quantum number.

This subshell can only accommodate a maximum of 10 electrons.

d- subshell has five orbitals

Each orbital is able to accommodate 2 electrons.

 Therefore 5 x 2 = 10 electrons
