Mg is magnesium. NO3 is nitrate. This gives you magnesium nitrate as an answer.
Answer:
HI (aq) → H⁺ (aq) + I⁻ (aq)
HI (aq) + H₂O(l) → H₃O⁺ (aq) + I⁻ (aq)
Explanation:
The Arrhenius acid concept indicates that a substance behaves like acid if it produces hydrogen ions H⁺ or hydronium ions H₃O⁺ in water. A substance will be classified as a base if it produces OH⁻ hydroxide ions in water. This way of defining acids and bases works well for aqueous solutions.
When we mix HI (aq) and water, we are increasing [H₃O⁺]
HI (aq) → H⁺ (aq) + I⁻ (aq)
HI (aq) + H₂O(l) → H₃O⁺ (aq) + I⁻ (aq)
Answer:
17.83M
Explanation:
Given parameters:
Mass of KCO₂ = 1.5kg
Volume of water = 850mL
Unknown:
Molarity of solution = ?
Solution:
Molarity is defined as the number of moles per unit volume. It is the number of moles of solute in a given volume of solution.
Molarity = 
Number of moles of solute = 
Molar mass of KCO₂ = 39 + 12 + 3(16) = 99g/mol
Number of moles = 
= 15.15moles
850mL : gives 0.85L
Molarity = 
= 17.83M
Answer: technetium-99.
Explanation:
This is not an answer that you can look for in a book.
You need to do some research.
You can fiind the abstract of the article titled <span>Molecular imaging of atherosclerosis using a technetium-99m-labeled endothelin derivative.</span>
The conclusion of this scientific article is that labeling with the radiosotope Tc - 99 iis feasibele to visualize the effects of an experiment inducing atherosclerosis, which gives the answer to the question posted.
