The periodic table is organized by the atomic mass of the elements. It means if the element is in Group 2a in the periodic table, it has 2+ ions.
you want to design a faster car
because thats engineering

testing evaporation is not engineering
and making slime isnt either...
lets say it like this do you use a wrench for slime or evaporation?
nope but you do for cars

According to provided equation it is clear that Zn metal is oxidized from Zn⁰ into Zn²⁺ which means that Zn metal dissolves and forming Zn²⁺ solution so the correct answer is:
mass of the Zn(s) electrode decreases
Answer:
C. Potassium-19
.
Explanation:
Hello!
In this case, since isotopes are known be atoms of the same element with equal atomic number but different mass number, we can consider the case of carbon which has two natural occurring ones, carbon-12 and carbon-13 whereas carbon-12 has the greatest abundance. However, isotope notation may take two forms:
1. Symbol of the element followed by a dash indicating the mass number of the isotope, for instance: C-12, K-39, and so on.
2. Name of the element followed by a dash indicating the mass number of the isotope, for instance: Carbon-12, Potassium-39, and so on.
In such a way, the improper isotope notation is C. Potassium-19
, considering that A should be K-39 because atomic symbol of potassium is K, not k.
Best regards!
