Please can anyone help? it's not that of s hard question but I can't really understand it.. In four experiments, zinc is added to acid to investigate how the speed of reaction can be
changed.

In the table, write more, less or the same in the final column to show the effect of each
change.

Please look at the picture for the table
I would really appreciate anyone who could help.
thank you!
p. s I will mark brainliest and vote!

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
