Q.

23

gram sodyum elementi

m

gram su ile etkileşime girerek

40

gram kostik ve

1

gram hidrojen gazı oluşturmaktadır. Buna göre,

m

değeri kaçtır?

\newline

A)

12

\newline

B)

18

\newline

C)

41

\newline

D)

64

\newline

E)

75

Understand Problem: Understand the problem and set up the equation based on the law of conservation of mass. $\newline$ Total mass of reactants = Total mass of products. $\newline$ $23$ grams (sodium) + $m$ grams (water) = $40$ grams (caustic) + $1$ gram (hydrogen).
Set Up Equation: Solve for $m$ . $23 + m = 40 + 1$ , $23 + m = 41$ , $m = 41 - 23$ , $m = 18$ .
