In the following chemical reaction, which element is shown to be violating the law of conservation of mass? C3H8 + 4O2 -&gt; 3CO
AlexFokin [52]
Checking if it is balanced:

C             
3               3

H
8                  4*2 = 8

O
8                  3*2   + 4 = 6 + 4 = 10
8                   10

Only O is not balanced.

So O is violating the law.     Option C.

A 5.00 mL of a salt solution of unknown concentration was mixed with 35.0 mL of 0.523 M AgNO3. The mass of AgCl solid formed was
Lapatulllka [165]

Answer:

The chemical term in the equation for the precipitate of AgCl(s) is n=3.54*10^-3

Explanation:

the quantity of AgCl(s) in moles is:

n = 0.508g / 143.32 g/mol = 3.54*10^-3 mol

to verify it the mass of AgNO3 involved in the reaction should be

n AgNO3 required = n = 3.54*10^-3 mol

the mass of n involved should be higher than n AgNO3

n existing = V*N = 0.523 mol/L * 35*10^-3 L = 18.305*10^-3 mol
