bija089 [108]

Answer:  The missing coefficient is 2.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

2NaOH+Ca(OH)_2+2Cl_2\rightarrow Ca(OCl)_2+2NaCl+2H_2O

As in the products, there are 2 atoms of sodium, thus there will be 2 atoms of  of sodium in the reactant as well.  This will balance the number of hydrogen and oxygen atoms as well.

Thus the missing coefficient is 2.

How many grams of Br are in 255 g of CaBr2?
Scilla [17]
Molar mass:

Br = 79.904 g/mol
CaBr2 = 199.886 g/mol

<span>CaBr2 = 2 Br + Ca
</span>
199.886 g --------------- 2 x 79.904 g
255 g -------------------- ?? ( mass of Br )

255 x 2 x 79.904 / 199.886 =

 40751.04 / 199.886 =>203.87 g of Br

hope his helps!
