Answer:
Mg²⁺(aq) + SO₃²⁻(aq) + 2 H⁺(aq) + 2 I⁻(aq) ⇄ Mg²⁺(aq) + 2I⁻(aq) + H₂O(l) + SO₂(g)
Explanation:
<em>Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of MgSO₃ and HI are mixed.</em>
When MgSO₃ reacts with HI they experience a double displacement reaction, in which the cations and anions of each compound are exchanged, forming H₂SO₃ and MgI₂. At the same time, H₂SO₃ tends to decompose to H₂O and SO₂. The complete molecular equation is:
MgSO₃(aq) + 2 HI(aq) ⇄ MgI₂(aq) + H₂O(l) + SO₂(g)
In the complete ionic equation, species with ionic bonds dissociate into ions.
Mg²⁺(aq) + SO₃²⁻(aq) + 2 H⁺(aq) + 2 I⁻(aq) ⇄ Mg²⁺(aq) + 2I⁻(aq) + H₂O(l) + SO₂(g)
A physical change is something that could be reverted back to its original form, while a chemical change is something that could not be reverted back when changed.
ex of physical change: ice - can be melted and then freeze to solid again
ex of chemical change: change of color, like adding food coloring in something and you cannot take out the color again
Answer:
thx hdhsbw dvd for gdgsbs the menej points
Answer:
b
Explanation:
b because it's a physical change
The total volume of the infusion in 10 mL (bupivacaine) + 10 mL (morphine) + 250 mL (saline solution) = 270 mL.
The number of drops is: (270 mL)*(20 drops/mL) = 5400 drops
If this is to be administered over 3 hours, or over 180 minutes, then the number of drops per minute is:
5400 drops / 180 minutes = 30 drops/minute
