Why would you use a solution, such as a cabbage ph indicator, to measure the ph of household items?

Hey there Budd!

One reason would be because, when you use this, because this has so many solutions, this would be the most helpful in this case, you would want to get as many as you can.

Hope this helps you!

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
