Answer:
NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃
Explanation:
A double replacement reaction is a reaction in which the cations switch anions.
In the reaction, the two cations are Al and Ni. The cations are Br and S.
Put each cation with the opposite anion: Ni with S and Al with Br.
The products would be NiS₃ and Al₂Br₃.
The full reaction is NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃.
Hope that helps.
Answer:
Acid - dilute nitric acid
Metal oxide - zinc oxide, zinc hydroxide or zinc carbonate
Explanation:
Zinc Nitrate is produced by carrying out a reaction between the following metal oxides and acid
Acid - dilute nitric acid as concentrated nitric acid produces ammonium nitrate
Metal oxide - zinc oxide, zinc hydroxide or zinc carbonate
Hence the correct answer is
Acid - dilute nitric acid
Metal oxide - zinc oxide, zinc hydroxide or zinc carbonate
A variable is an element, feature, or factor that is liable to vary or change.
B. not fully absorbed by the atmosphere.
Explanation:
Visible light, which has a wavelength of between 380nm and 760nm is usually not fully absorbed by the atmosphere.
The earth's atmosphere is transparent to visible light emanating from the sun.
When visible light is radiated out from the sun, on reaching the atmospheric cover of the earth, it goes through without restraints.
- Little to no interaction occurs between the atmospheric cover of earth and visible light.
- This is why the surface is bright and receives sunlight.
- Other more energetic radiations interacts with atmosphere.
- Some of them gets cut off and some partially penetrate through.
