Answer:
The answer to your question is 432 g of CO₂
Explanation:
Data
CaCO₃ = 983 g
CaO = 551 g
CO₂ = ?
Balanced reaction
CaCO₃ (s) ⇒ CaO (s) + CO₂ (g)
This reaction is balanced, to solve this problem just remember the Lavoisier Law of conservation of mass that states that the mass of the reactants is equal to the mass of the products.
Mass of reactants = Mass of products
Mass of CaCO₃ = Mass of CaO + Mass of CO₂
Solve for CO₂
Mass of CO₂ = Mass of CaCO₃ - Mass of CaO
Mass of CO₂ = 983 g - 551 g
Simplification
Mass of CO₂ = 432 g
Answer:
19.9 moles
Explanation:
Each mole has 6.02 x 10^23 many atoms. This number is commonly known as "Avogadro's Number."
In this problem, we have 1.2 x 10^25 atoms of phosphorus.
Thus, (1.2 x 10^25)/(6.02 x 10^23) is the number of moles in 1.20 x 10^25 many atoms of phosphorus.
(1.2(10^25))/(6.02(10^23))
19.9 moles.
When sulfur dioxide reacts with water , the product is called sulphurous acid, H2SO3. The balanced equation is expressed in the following manner : SO2 + H2O = H2SO3. There is a one mole to one mole ratio between any of the reactants to product, sulphurous acid.
