Answer:

Both electrons of Mg should be transferred to one O.

Explanation:

This is because metals like to lose electrons whereas non metals like to gain electrons in an ionic compound. MgO is an ionic compounds. So Magnesium being a metal in group 2 of periodic table, it wants to donate 2 electrons to get to the octet rule, so it donates its electrons and oxygen accepts them to fill its octet rule.

Answer B

Mg has a positive ionic charge because it hoped to loose its two electrons to make it stable or happy

O had a negative ionic charge bc it wants to gain electrons to make it stable or happy

therefore,

QA) O would not want/wouldn't use up the energy to transfer 6 of its electrons and Mg would accept O's electrons
Q3) goes against laws of chemistry
Q4) Mg can not gain 2 extra electrons unless it is a double molecule (which it is not) a

A solution of a weak acid was tested with the following indicators and the colors noted: Methyl Violet - violet Thymol Blue - ye

blsea [12.9K]

pH ranges depending on the solution, for a solution with weak acid pH will be between 4.0-7.0.

pH is helps to determine if a solution is acidic or basic in nature.

A pH meter is the instrument that can be used for the measurements.

Methyl orange is used when titrating a strong acid against a weak base.

Therefore, the pH of the solution which is a weak acid will be between 4.0-7.0.

olganol [36]

2/3 is the fraction of the carbon dioxide exhaled by all of the animals that is generated by the reactions of the citric acid cycle, if the gluscose is the sole energy source. So if the glucose is the energy source the fraction of the carbon dioxide is 2/3. The answer in this question is 2/3

Different elements emit different emission spectra when they are excited because each type of element has a unique energy level

jonny [76]

Different elements emit different spectra when their electrons get excited because each element has a different arrangement of electrons surrounding the nucleus. The energy levels in which the electrons can occupy are unique to a specific element. When an electron gets excited into a higher energy level, it will eventually relax back into its original state and emit light corresponding to that energy.
