How many molecules are in 5.5 moles of CUNO3?
Setler [38]

Answer:

1.48381734165x 10²⁵ molecules

Explanation:

1 grams CuNo3 is equal to 0.0011897028836018 mole.

x = 5.5 moles

x = 5.5 x 1/0.0011897028836018 = 5.5/0.0011897028836018

4623.003grams

the molar mass of cuno3 =187.56 = 6.02 x10²³

4623.003g = x

187.56x = 4623.003 x 6.02 x10²³  = 27830.47806 x10²³ =  1.48381734165x 10²⁵

Consider the following reaction: 2HI(aq)+Ba(OH)2(aq) → 2H2O(l)+BaI2(aq) Enter the complete ionic equation for this reaction. Exp
babunello [35]

Answer:

2 HI(aq) + Ba²⁺(aq) + 2 OH⁻(aq) → 2 H₂O(l) + Ba²⁺(aq) + 2I⁻(aq)

Explanation:

Let's consider the following balanced molecular equation.

2 HI(aq) + Ba(OH)₂(aq) → 2 H₂O(l) + BaI₂(aq)

In the complete ionic equation we include all the ions and the species that do not dissociate in water. HI is a weak electrolyte so it exists mostly in the molecular form. H₂O has a very low equilibrium constant (Kw = 10⁻¹⁴) si it exists mainly in the molecular form.

2 HI(aq) + Ba²⁺(aq) + 2 OH⁻(aq) → 2 H₂O(l) + Ba²⁺(aq) + 2I⁻(aq)
