bases have a ph lower than 7 is false. it's actually acids that have a ph lower than 7, 7 is neutral, and above 7 to 14 is basic.

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

answer
