Answer:
240.5g
Explanation:
steps:
given/ 1 - 2.5mol LiBr / 1
Multiplication - 78g/ 1 mol ( 78 comes from the formula weight of LiBr )
answer- 240.5g
Freezing point is the temperature at which a substance undergoes a phase transition from liquid to solid state. Water converts from liquid state to solid ice at a temperature of 
.
Mass is the amount of matter contained in a substance. The SI unit of mass is kilogram. 1 kilogram is equal to 1000 g. One kilogram is defined as the mass of one cubic decimeter of water at the freezing point of water.
Answer:
The reaction rate would decrease
Explanation:
The equation for the Haber process is given by;
N₂(g) + 3H₂(g) ⇆ 2NH₃(g)
- The reaction occurs at a temperature of 500°C
- Therefore, the forward reaction requires a temperature of 500°C.
- According to Le Chatelier's principle, if a factor affecting equilibrium is altered, the equilibrium will shift in the direction that counteracts the effect causing it.
- In this case, decreasing the temperature to 100°C will lower the rate of the forward reaction.
- Consequently, less ammonia gas will be produced as the reverse reaction is favored.
Water is an essential part of life and its availability is important for all living creatures. On the other side, the world is suffering from a major problem of drinking water. There are several gases, microorganisms and other toxins (chemicals and heavy metals) added into water during rain, flowing water, etc. which is responsible for water pollution. This review article describes various applications of nanomaterial in removing different types of impurities from polluted water. There are various kinds of nanomaterials, which carried huge potential to treat polluted water (containing metal toxin substance, different organic and inorganic impurities) very effectively due to their unique properties like greater surface area, able to work at low concentration, etc. The nanostructured catalytic membranes, nanosorbents and nanophotocatalyst based approaches to remove pollutants from wastewater are eco-friendly and efficient, but they require more energy, more investment in order to purify the wastewater. There are many challenges and issues of wastewater treatment. Some precautions are also required to keep away from ecological and health issues. New modern equipment for wastewater treatment should be flexible, low cost and efficient for the commercialization purpose.
