Explanation:
- The products formed are chromic chloride and cobalt.
Chromium + Cobaltous Chloride = Chromic Chloride + Cobalt
- Type of reaction is Single Displacement (Substitution) which is there is a displacement of one atom.
Reactants used in the reaction are -
- Chromium

- Cobaltous Chloride

Products formed in the reaction are -
- Chromic Chloride

- Cobalt

Hence, the chemical reaction is as follows -
→
For balancing the above chemical equation we need to add a coefficient of 2 in front of chromium and of 3 in front of cobalt(II)chloride on right-hand-side while of 2 in front of chromium chloride and of 3 in front of carbon monoxide on left-hand-side of the equation.
Hence, the balanced equation is -
→ 
CFC-11 is typically the CFC with the shortest atmospheric lifetime.
The answer to this is 22, confirmed by gradpoint
Answer:
2cm^3
Explanation:
Use the density triangle: D=MxV
Switch for variables, V=M/D
Plug in numbers, 15.8g/7.9g/cm^3=2cm^3
Answer:
Answer: A. Gases are easily compressed because of the low density.
