Answer:
850g/min
Explanation:
The reaction expression is given as:
P₄ + 5O₂ → P₄O₁₀
Given that:
Number of moles of product = 1.5moles
Time = 30s = 0.5min
Unknown:
The rate of the reaction = ?
Solution:
Convert the moles given to mass of the product.
So;
Mass of product = number of moles x molar mass
Molar mass of P₄O₁₀ = 4(31) + 10(16) = 284g/mol
Mass of product = 1.5moles x 284g/mol = 426g
So;
Reaction rate = 
= 
= 850g/min
The arrangement of particles in a gas is random. they have no orderly arrangement and are free to move around while the particles in solid are in an orderly and rigid arrangement and cannot move about. particles in liquid are also arranged orderly but are not rigid
Before you begin titration, drops of indicator are added to the Erlenmeyer flask. This happens when preparing to measure pH change.
Best Answer: 4.52 X 10²³ atoms. Use Avogadro's number to multiply 0.750 moles times 6.022 X 10²³
