Yep u right bro but like you know I’m here with these guys you know what I mean tho
Ions and charges= Al+3 SO3-2
The charges must add up to zero, in order for two +3 aluminum ions to cancel out three -2 sulfite ions.
Al+3 Al+3 SO3-2 SO3-2 SO3-2
<span>So simply put : </span>Al2(SO3)<span>3 </span>
A) 7.5 % m / V
7.5 g -------- 100 mL ( solution )
mass g ------ 45.0 mL
mass g = 45.0 x 7.5 / 100
mass g = 337.5 / 100 => 3.375 g
1 mole KCl -------------- 74.55 g
moles KCl ---------------- 3.375 g
moles KCl = 3.375 x 1 / 74.55 => 0.0452 moles of KCl
______________________________________________
b) 9.5 % ( m / V ) :
9.5 g -------- 100 mL ( solution )
mass g ------ 400.0 mL
mass g = 400.0 x 9.5 / 100
mass g = 3800 / 100 => 38 g
1 mole acetic acid -------------- 60.05 g
moles acetid acid ---------------- 38 g
moles acetid acid = 38 x 1 / 60.05 => 0.6328 moles of acetid acid<span>

hope this helps!
Answer:
We are asked to describe the half-life of the radioactive materials.
- Hence the 3rd option is correct
Answer:
In simple terms, this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of the mass of reacting mixture and the products formed remains constant.
