Density = mass/ volume
mass= 9.6 g
Volume of the object = 13.2-10.0 =3.2 ml=3.2 cm³
1ml =1 cm³
D=9.6g/3.2 cm³ = 3.0 g/cm³
Answer:
First Option: B)
Second Option: C)
<em>The pictures below will show the answers. The first picture is the first option, and the second picture is the second option.</em>
<em></em>
C definitely is the answer
Al+3is the third electron ionization level of the atom Al.
Al has an atomic number of 13, thus it has 13 protons and electrons.
By shooting a photon with a certain amount of energy (the energy in kj/mol) the atom will be ionized and lose the electrons.
13-3 = 10
The total amount of electrons in Al3+ is 10 <span>*The energy required to ''detach'' 3 electrons from the 3s and 3p orbital.</span>
Answer:
The titrant is a strong acid while the analyte is a strong base
Explanation:
A titration curve is a graphical representation of the pH of a solution during a titration. The figure in the question shows a particular example of a strong acid-strong base titration curve. This is a titration in which the acid is added to the base thus the pH progresses from low to high.
Hence, the titrant is the strong acid delivered from the burette while the analyte is the base as shown by the titration curve in which acid is delivered to the base.
