Conservation of mass is the underlying principle of balancing equation. When we balance equation, this means that we acknowledge that before and after the chemical reaction, the elements are conserved. To balance the chemical equation, we add coefficients before each reactant and product. Here are the following answers:
Reaction 1:
<span>2Al
3ZnCl2
3Zn
2AlCl3
Reaction 2:
</span><span>4NH3
3O2
2N2
6H2O</span>
Answer:
Models make some things easier to understand.
Measurements can be made only on models.
Models help scientists visualize things they can’t see.
Models are perfectly accurate representations of objects.
Scientists can analyze models to make predictions.

Mark as brainliest......
222.5 g
I did it like this:
X/250= 89/100=
22250/100=
222.5
You cannot create something from nothing and similarly you cannot create less from more, if you didn't balance an equation that needs to be balanced, your product might end up equalling more or less than the total mass of the two elements combined. Which is impossible
