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)
Matter and substance are definitely related. All substances
are matter but all matters are not substance. A matter can consist of numerous
substances. Matter is generally a loose term used in respect to a substance.
Any physical object can be casually called a matter. Matter and substance are
sometimes used for the same context, but it is completely wrong. Numerous
examples have already proved that a matter may or may not be a substance
depending on its physical nature, but a substance is always a matter.
Answer:
Do it your self bro
Explanation:
You lazy bum do it yourself
0.01068g
Explanation:
Given parameters :
Number of atoms = 5.34 x 10²⁰ atoms
Molar mass of carbon = 12g
Unknown:
Mass of carbon = ?
Solution:
A mole of a substance is unit that contains the Avogadro's number of particles.
1 mole = 6.02 x 10²³ atoms ;
In 5.34 x 10²⁰ ;
Number of moles = 
= 8.9 x 10⁻⁴moles
Mass = number of moles x molar mass = 8.9 x 10⁻⁴ x 12 = 0.01068g
