Mass of B₂ = 18.75 g
<h3>Further explanation</h3>
Given
Element A and element B
Required
The reaction
mass of B₂
Solution
The balanced equation :
2A(s) + B₂(g) ⇒2AB(s)
mol AB :
= Molarity x Volume
= 2.5 M x 0.25 L
= 0.625
From the equation, mol ratio of B₂ : AB = 1 : 2, so mol B₂ :
= 1/2 x mol AB
= 1/2 x 0.625
= 0.3125
Mass B₂ (Molar mass = 2x30 g/mol=60 g/mol)
= mol x molar mass
= 0.3125 x 60 g/mol
= 18.75 g
Answer:
0,218 moles
Explanation:
I will first explain how many liters is 256ml, that is 0,256 l.
because the m stands for milli which is a factor of 1000 -> (256 ml / 1000 = 0,256 l)
To calculate the amount of moles you multiply the volume with the concentration. So 0,256l x 0,855M = 0,218 moles.
Answer:
The Resource Conservation and Recovery Act (RCRA; PL 94-580), the major federal law on waste disposal, was passed in 1976. Its primary goal was to "protect human health and the environment from the potential hazards of waste disposal." RCRA is also concerned with reducing the amount of waste generated, ensuring that wastes are managed properly, and conserving natural resources and energy. The RCRA regulates solid waste, hazardous waste, and underground storage tanks
