Answer:
Hi
2-methyl-1-propanetiol is found in alcoholic beverages. It is a food additive, and is also found in guava, milk, cooked beef, cooked pork and beer. It is also used as a flavoring. A dose of 7168 mg / kg produces muscle weakness, ataxia, cyanosis. An intraperitoneal dose of 917 mg / kg can cause nervousness and a feeling of spastic paralysis. In the attached file is the scheme.
Explanation:
The balanced equation of NaOH and H2SO4 would be:
2NaOH + H2SO4 = Na2SO4 + 2H2O
To determine the concentration of NaOH, we first find the moles of NaOH used in the reaction. We start with the the concentration and volume of H2SO4. We do as follows:
2.00 M H2SO4 ( 0.25 L ) = 0.5 mol H2SO4
0.5 mol H2SO4 ( 2 mol NaOH / 1 mol H2SO4) = 1 mol NaOH
Molarity = 1 mol NaOH / 2.00 L NaOH solution = 0.5 M NaOH solution
Answer:
I think it's lead (pb). Hope this helps.
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.
