In chemical reactions, what does the principle of conservation of mass mean?
Scilla [17]
I think It means that any balanced equation is conserved. Meaning that the equation is equal. The law states matter can’t be created or destroyed. In chemical reactions the mass of an element is the same before and after the product. There’s two sides two an equation the reactants side and the product’s side. Hope this helps.

A 1170.-gram sample of NaCl() completely reacts, producing 460. grams of Na(). What is the total mass of Cl2(g) produced?
777dan777 [17]
2 NaCl --------> 2 Na  + Cl₂
  
2 mol * 23 g Na = 46 g

2*35,5 g Cl = 71 

 46 g Na --------- 71 g Cl₂
 460 g Na -------- ?

mass ( Cl₂) = 460 . 71 / 46

Mass (Cl₂) = 32660 / 46

m= 710 g of Cl₂

A metal ion (X) with a charge of 2+ is attracted to a nonmetal ion (Z) with a charge of 3-.Which formula represents the resultin
Viefleur [7K]

Answer:

X₃Z₂

Explanation:

A metal ion (X) with a charge of 2+  =  X²⁺

nonmetal ion (Z) with a charge of 3-   = Z³⁻

In a neutral compound, the charges but balance each other to remain neutral. However in this case, the charges are not balanced.

A simple way to make the charges balance is by tweaking the number of the ions present in the compound.

We do this by multiplying the metal ion with 3 and the non metal ion by 2.

That way we have;

Metal ion = 3X2⁺   (Total charge - 6⁺)

Non metal ion = 2Z3⁻  (Total charge -  6⁻)

The charges are now balanced. The formular of the compound is;

X₃Z₂

Which of the following types of molecular representations can be used to show differences between isomers? Explain why each can
Ludmilka [50]
Isomer is defined as compounds with the same formula but different arrangement of atoms in its molecule and they differ in their properties. The <span>representation that can be used to show differences between isomers is the use of structural formula.  It shows the arrangement of each atoms. It cant be molecular formula and 3D drawing because it does not show the arrangement of the atoms.</span><span>
