Question

•H2 = HBr = KBr = AgBr

Answer 1

1) H₂ + Br₂ = 2HBr
2) 2HBr + 2K = 2KBr + H₂↑
3)  KBr + AgOH = AgBr↓ + KOH

Answer 2

H2+Br2=2HBr
HBr+KCL=KBr+HCL
KBr+AgNO3=KNO3+AgBr

Answer 3

The equation you provided, "H2 = HBr = KBr = AgBr," seems to be comparing different substances. Let's break down what each part represents:

1. H2: This represents molecular hydrogen, which consists of two hydrogen atoms bonded together to form a diatomic molecule (H2).

2. HBr: This represents hydrogen bromide, a chemical compound composed of hydrogen (H) and bromine (Br) atoms.

3. KBr: This represents potassium bromide, a chemical compound composed of potassium (K) and bromine (Br) atoms.

4. AgBr: This represents silver bromide, a chemical compound composed of silver (Ag) and bromine (Br) atoms.

It appears that you are comparing these substances. If you have a specific question or need more information about these compounds or their properties, please feel free to ask.
