Answer:
Its C
Explanation:
The law of conservation of mass says no atoms can be created or destroyed just rearranged so the mass at the beginning before the reaction would stay the same after it
Considering the Law of Conservation of Matter, the correct answer is the third option: the total mass of the products will be the same and has a value of 58.44 amu.
The Law of Conservation of Matter is also called the law of conservation of mass or the Law of Lomonósov-Lavoisier. This law postulates that "the mass is not created or destroyed, only transformed."
This means that the reagents interact with each other and form new products with physical and chemical properties different from those of the reagents because the atoms of the substances are ordered differently. But the amount of matter or mass before and after a transformation (chemical reaction) is always the same, that is, the quantities of the masses involved in a given reaction must be constant at all times, not changing in their proportions when the reaction ends.
In other words, then the mass before the chemical reaction is equal to the mass after the reaction.
So, in this case, if the total mass of the reactants is 58.44 amu, the total mass of the products will be the same and has a value of 58.44 amu.
Finally, the correct answer is the third option: the total mass of the products will be the same and has a value of 58.44 amu.

For This activity, you will create a diagram for each of the solutions you tested showing the dissolved solutes. Make sure to label the correct charges on the ions and circle the solutes that do not have charge. include a brief explanation under each diagram of its conductivity. Finally, write a brief explanation of what would happen to the conductivity of the ionic solutions if you were to mix in a covalant compound such as a sugar or one of the covalent solutions. Where have you seen a similar experiment and results?
Ionic solutions are known to be electrolytes due to the presence of free ions. Covalent solutions are non-electrolytes hence the decrease the conductivity of the ionic solutions.
Electrolytes are solutions that conduct electricity. The charge carriers in solution are ions. These ions are mobile. Covalent substances are molecular in nature. They do not contain ions hence they do not give ions when dissolved in water.
The conductivity of ionic solutions owes to the presence of ions in solution. The higher the concentration of ions in solution, the greater the conductivity of the solution. When covalent substances are mixed with ionic solutions, the concentration of ions decreases and the conductivity of the solution decreases.

a mixture in which substances are distributed evenly
electronegativities of the elements be, mg, ca, and sr follow a specific trend within their group. based on this trend, the atoms of which element will have the least attraction for an electron?
Based on the trend of electronegativities values of the elements Be, Mg, Ca, and, Sr within their group (increasing from bottom to top), the atoms of the element Sr will have the least attraction for an electron.
We need to remember that electronegativity indicates the affinity or attraction of an element for an electron. Hence, the higher the electronegativity, the higher the attraction of that element for an electron.
The values of electronegativities of the given elements are the following:
Be = 1.57
Mg = 1.31
Ca = 1.0
Sr = 0.95
We can see that the increasing trend of electronegativities in this group is from the bottom to the top, having the Sr with the lowest electronegativity value and the Be with the highest.
This trend is related to atomic size, the larger the atomic size, the lower the electronegativity because the electron in the outermost shell will feel less attraction towards the nucleus of an atom. In a group of the periodic table, the size of an atom will increase from top to bottom.
Therefore, according to the said above, the atoms of the Sr will have the least attraction for an electron (it has the lower electronegativity value).
