Answer:

The chemical change is "Frying an egg".

Explanation:

  • As the thermal energy is present while cooking an egg, these same components of such an egg transform their appearances as well as their consistency probably forever.
  • Throughout the process of denaturation, the above transformation process or strategy of such a fried egg can't be completely overturned.

Thus the above is the right answer.

24. Element X has five valence electrons, element Y has one valence electron, and element Z has one valence electron. Which two
natka813 [3]
Elements Y and elements Z would have similar properties due to the fact that they both posses the same number of valence electrons. They both have a single valence electron that determines the corresponding elements bonding properties and the fact that it can either donate 1 valence electron to produce an ion that would be attracted to another atom, that is also an ion. Assuming that these elements are group 1 elements, they do not undergo in covalent bonding.

Complete the equation for the dissociation of Fe(ClO4)3(aq). Omit water from the equations because it is understood to be presen
victus00 [196]

Answer:

The equation that tends to answer this question, (omitting the presence of water) is:

Fe (ClO4) 3 -----------> Fe (+3) + ClO4 (-1)

Explanation:

The numbers that we see in parentheses would be the oxidation numbers of each compound, in the case of iron, iron acts with an oxidation number of +3, and in the case of perchlorate it would be -1.

The stoichiometric name according to IUPAC (most widely used chemical nomenclature) is iron perchlorate.

A chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water. What is the concentration of the final solution? U
Aleks [24]
Hello!

The concentration of the final solution when a<span> chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water is 0,3 M

To calculate that, you'll need to use the dilution law, where initial and final concentrations are M1 and M2 respectively, and initial and final volumes are V1 and V2, as shown below. Keep in mind that the final volume is the sum of the 200 mL of water and the 50 mL of H</span>₂SO₄ that were added by the teacher. 

M2= \frac{M1*V1}{V2}= \frac{1,50 (mol H_2SO_4/L)*50mL}{(50 mL + 200 mL)}=0,3(mol H_2SO_4/L)

Have a nice day!

Salsk061 [2.6K]

Answer:

34- Solid

35-Metals form metallic bonds releasing one or more valence electrons to form a common electron reservoir which contains free mobile elactrons who will conduct electricity well.

36 When the cation is formed electrons are removed and the effective positive neuclear charge increases and it makes the remaining electrons accumulate around the neucleous making the cationic radius smaller than that of the atom
