You know from the chemical formula that 1 mole of Cu3(PO4)2 contains 2 moles of P so you can work out how many moles of P are in 8.1 moles of Cu3(PO4)2.
<span>As for anything, 1 mole of X contains 6.022 * 10^23 of X. Multiply moles of X by Avogadro's number.</span>
Answer:
Number of moles = 0.51 mol
Explanation:
Given data:
Mass of CO₂ = 22.4 g
Number of moles = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Molar mass of CO₂ = 44 g/mol
by putting values,
Number of moles = 22.4 g/ 44 g/mol
Number of moles = 0.51 mol
Answer: This is due to a dominance of political parties over ... legislative process, the influence opposition has on amending the government bills and formal and effective
Explanation: hope u get it right
The Molecular Equation is as follow,
Ba(NO₃)₂ ₍aq₎ + MgSO₄ ₍aq₎ → BaSO₄ ₍s₎ + Mg(NO₃)₂ ₍aq₎
The Total Ionic Equation is as follow,
Ba²⁺₍aq₎ + 2NO₃⁻ ₍aq₎ +Mg²⁺ ₍aq₎ + SO₄²⁻ ₍aq₎ → Mg²⁺ ₍aq₎ + 2NO₃⁻ ₍aq₎ + BaSO₄ ₍aq₎
Here, Mg²⁺ and NO₃⁻ are spectator Ions,
So,
The Net Ionic Equation is as follow,
Ba²⁺ ₍aq₎ + SO₄²⁻ ₍aq₎ → BaSO₄ ₍aq₎
Answer:
A. Hydrogen gas combining with oxygen gas to form water.
Explanation:
H2 is the symbol for Hydrogen in gaseous state and O2 is the symbol for Oxygen in gaseous state. H2O is the chemical formula of Water. It is clearly indicated in the equation that Hydrogen and Oxygen combining to form Water.
The arrow to the water indicate that the water is the product and it is NOT the decomposition reaction.
