The answer is D. Nothing
T<span>he only thing that must remain equal as stated in the Law of Conservation of Mass are the same number of atoms of each element on each </span><span>side of a chemical equation. </span>
Because <span> The half-life of carbon-14 is around 5,700 years. So, by measuring the half-live of the sample, we could predict how old the sample actually is.
</span><span>After 50,000 years there is probably less than 1% of the original C-14 left which make it much more accurate to measure, so, the upward limit is put on 50,000 years.</span>
Easy you can't touch the subscripts so u need to add coiffents like a puzzle if you do this then it will chance this 1st name each element on each side then say how much it's worth then see what you need to chance like this
Ti=1
Cl=4
Mg=1.
On the other side
Ti=1
Mg=1
Cl=2. What do you need to change using coffients
Answer:
increases as you move down a group as the number of electrons increases. Therefore, the atomic radius increases as the group and energy levels increase
