Physical change
the identity of the steak does not change
Answer:
OH-
Explanation:
H2O can act as base or acid.
When H2O acts as a base the conjugate acid is H3O+
When H2O acts as an acid the conjugate base is OH-

Explanation:
In order to calculate the number of moles of a compound, we will find it out as follows.
No. of moles of chromium(III) chloride =
=
= 0.63 moles
No. of moles of
=
=
= 5.88 moles
No. of moles of
=
=
= 1.05 moles
No. of moles of
=
=
= 1.02 moles
No. of moles of KCl =
=
= 1.34 moles
No. of moles of
=
=
= 1.31 moles
No. of moles of
=
=
= 6.25 moles
No. of moles of
=
=
= 2.27 moles
No. of moles of
=
=
= 1.11 moles
Therefore, we can conclude that out of the given options
contains the largest number of moles of compound.
Answer:
These tests determine the solubility of the compounds formed upon adding the test solution
Explanation:
Addition of Ba(NO₃)₂ will cause a precipitate ((Ba)₂SO₄) to form in the solution of (NH₄)₂SO₄. No precipitates will form in the other unknown solutions. Thus, whether or not the solution is ammonium sulfate can be determined.
Addition of NaCl solution will cause a precipitate (AgCl) to form in the solution of AgNO₃. No precipitates will form in the other unknown solutions. Thus, whether or not the solution is silver nitrate can be determined.
If no precipitates form, then the unknown solution must be KCl.
