Plz, if litmus paper is dipped into an acidic solution and then a basic one what will happen a. it will turn from blue to red b. the paper will turn from red to clear c. the paper will turn from blue to clear d. the solution will turn from red to blue

the paper will turn red

Explanation:

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
