Question

tentukan biloks yang di bawahi

1. Ca3 (P O4)2. *garis bawah P

2.Na2 S2 03. *garis bawah S

​

Answer 1

Jawaban:

1. P= 5

2. S = 2

Penjelasan:

1. Ca3(PO4)2

2(3) + 2P + (-2)(8) = 0

6 + 2P + (-16) = 0

2P-10 = 0

2P = 10

P = 10/2

P = 5

2. Na2S2O3

1(2) + 2S + (-2)(3) = 0

2 + 2S + (-6) = 0

2S - 4 = 0

2S = 4

S = 4/2

S = 2

semoga benar dan membantu^^
