Explanation:
First lets calculate the volume of the silver cube The length of a side = 0.62 m Volume
Answer:
a) solubility increases
b) solubility decreases
c) solubility increases
Explanation:
I) Fe^3+(aq) + 3Br^- --------> FeBr3 (aq) solubility increases
II) Fe^3+(aq) + 3OH^- ---------> Fe(OH)3(s) solubility decreases
III) Fe^3+(aq) + 6CN^- -----------> [Fe(CN)6]^3- (aq) solubility increases
The ionic equations shown above shows the possible changes in solubility when Fe(OH)3 is added to each of the solutions mentioned in the question.
<h3><u>Answer;</u></h3>
+2
<h3><u>Explanation</u>;</h3>
- The electron configuration ofthe atom is 1s2 2s2 2p6 3s2. Upon forming an ion, its new configuration is 1s2 2s2 2p6.
- The atom has lost two electrons to form an ion which is positively charged with a charge of +2.
- In the given electronic configuration of an atom, '3s' shell is the outermost shell in which two electrons are present. For the stable configuration, these two electrons will be lost easily from the outer shell and atom will carry (+2).
- The atom has 12 electrons, and looses 2 electrons to attain stable configuration forming a positively charged ion with 10 electrons.
Answer:
C) Reactants absorb a minimum amount of energy and then release a smaller
amount of energy as products form.
Explanation:
The statement that best describes how to read a reaction pathway from the graph of an endothermic reaction is that, reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.
In an endothermic change, heat is absorbed from the surrounding.
- As such, the surrounding becomes colder at the end of the reaction.
- On a graph of an endothermic reaction, the reactants absorbs a minimum energy.
- As the reaction proceeds, the products gives off an even lesser amount of energy.
