Để giải câu hỏi Toán học trên, ta cần áp dụng các khái niệm và công thức về phản ứng hóa học và tính chất của các chất.

a) Viết PTHH (phương trình hoá học) xảy ra:
2 Cu + Cl2 -> 2 CuCl2

b) Để tính thể tích khí Clo (V) đã tham gia phản ứng, ta cần sử dụng mối quan hệ giữa khối lượng, số mol và thể tích trong đktc của một chất khí. Công thức đưa ra là: m = M * n = V * d

Với m là khối lượng khí Clo đã tham gia phản ứng (cần tìm), M là khối lượng mol khí Clo, n là số mol khí Clo, V là thể tích khí Clo (cần tìm) và d là mật độ khí Clo ở đktc.

Đầu tiên, ta cần tính số mol của khí Clo (n). Ta biết rằng 1 mol khí Clo có khối lượng là 71 g (tính theo đơn vị mol). Vậy số mol dựa trên khối lượng 12,8 g là:

n = m/M = 12,8/71 = 0,18 mol

Tiếp theo, ta dùng số mol để tính thể tích (V). Với khí Clo ở đktc, 1 mol sẽ chiếm thể tích là 22,4 L. Vậy:

V = n * 22,4 = 0,18 * 22,4 = 4,032 L

Do đó, thể tích khí Clo ở đktc đã tham gia phản ứng là 4,032 L.

c) Để tính khối lượng muối đồng (II) Clorua (CuCl2) thu được, ta cần xác định số mol của muối CuCl2 từ số mol của khí Clo đã tham gia phản ứng. PTHH cho thấy rằng 2 mol Cu sẽ tương ứng với 1 mol CuCl2.

Số mol CuCl2 = n/2 = 0,18/2 = 0,09 mol

Sử dụng khối lượng mol của CuCl2 là 134,5 g/mol, ta có:

m = M * n = 134,5 * 0,09 = 12,105 g

Vậy khối lượng muối đồng (II) Clorua thu được là 12,105 g.
