Calculate the number of moles in 200 grams of Sodium hydroxide​

Chemistry
1 answer:
TEA [102]3 years ago
6 0

Answer:

The answer is 5 mol

Explanation:

Number Of Moles = Mass Of Substance ÷ Mass Of One Mole

Mass of NaOH = Molar Mass of Sodium + Oxygen + Hydrogen

23 + 16 + 1

40 g/mol

Number of Mole = 200/40 = 5 mol

Thus, The number of Moles in 200 grams of Sodium hydroxide is 5 mol

What stresses will shift the reaction to increase the products
AveGali [126]

Answer:

Change in molarity, temperature, volume/pressure depending on the conditions given

Explanation:

It really depends on the type of a reaction, however, we may apply general trends and see every possibility:

  • if we increase the concentration of products, then, according to the principle of Le Chatelier, the equilibrium will shift toward the formation of products;
  • if we have an endothermic reaction, increasing heat will lead a shift to the right and toward formation of products, since heat might be considered a reactant as well;
  • if we have an exothermic reaction, removing heat/decreasing temperature will lead to an increase in products, as we're removing one of our products, heat, and system will try to rebuild the amount of heat lost forming the other products as a result as well;
  • if we have gaseous substances in a reaction, an increase in pressure will shift the equilibrium to the right if we have a greater amount in moles of reactant gases compared to products, this is also known as a decrease in volume;
  • if we have gaseous substances in a reaction, a decrease in pressure will shift the equilibrium to the right if we have a greater amount in moles of product gases compared to reactants, this is also known as an increase in volume.

Answer:

2.4 billion years ago

Explanation:

  • The formation of the tertiary atmosphere, with the re-arrangements of the plates, took  that influenced the long term evolution of the planet that transferred the carbon dioxide to the large continental stores and the surplus oxygen came into formation about 2.4 billion years ago during the massive oxygenation event that leads to the appearance at the end of the banded iron formations.  
  • The process of photosynthesis also added and reduced the material that reduces the oxidation of the atmosphere and kept ion place till 15% of the Precambrian period had ended.
