Answer:
0.0010 w/v %
Explanation:
Based on the reaction:
NiCl₂(aq) + 2AgNO₃(aq) → 2AgCl(s) + Ni(NO₃)₂(aq)
Finding the moles of AgCl produced we can find the moles of NiCl in the reaction medium and its mass:
<em>Moles AgCl -Molar mass: 143.32g/mol-:</em>
5.8mg = 5.8x10⁻³g * (1mol / 143.32g) = 4.047x10⁻⁵ moles AgCl
<em>Moles NiCl₂:</em>
4.047x10⁻⁵ moles AgCl * (1mol NiCl₂ / 2mol AgCl) = 2.023x10⁻⁵ moles NiCl₂
<em>Mass NiCl₂ -Molar mass: 129.60g/mol-:</em>
2.023x10⁻⁵ moles NiCl₂ * (129.60g / mol) = 2.62x10⁻³g of NiCl₂ are produced.
And the concentration in w/v% is:
2.62x10⁻³g NiCl₂ / 250mL * 100 =
<h3>0.0010 w/v %</h3>
Yes it is h20 is a strong base
Answer: Option (B) is the correct answer.
Explanation:
Natural gas is defined as the gas which is formed naturally beneath the surface of Earth that mostly contains methane and small amounts of ethane, propane etc.
Since, natural gas upon burning produces water and carbon dioxide resulting in the release of a clean gas as compared to other fuels. Carbon dioxide produced upon burning of natural gas is 50-60% lesser in amount as compared to release of carbon dioxide upon burning of coal.
Therefore, we can conclude that burning coal produces more carbon dioxide than burning natural gas.
