<h3>Answer:</h3>
Option-C: HCl + H₂O → H₃O⁺ + Cl⁻
Explanation:
Bronsted-Lowery concept of Acid and Base defines Acid as that specie which tends to donate H⁺ (Hydrogen Ion) and bases are those species which accepts H⁺ from Acids.
In selected option, HCl is reacting as Acid as it donates H⁺ to water (lowery bronsted base).
Also, the correspong acid is converted into conjugate base (i.e. Cl⁻) and base is converted into conjugate acid (i.e. H₃O⁺)
Answer:
No, the puddle was formed because of the sun, because if there was snow and it rained then it would have turned slippery or icy
Answer:
The correct answer is 3.675 moles.
Explanation:
Based on the question, the reaction taking place is,
Tl₂(O₂)₃ ⇒ 2Tl⁺³ + 3O₂⁻²
Thus, 1 mole of thallium peroxide comprise 2 moles of thallium and 3 moles of peroxide ions.
However, based on the given question, a sample of thallium peroxide comprise 2.45 moles of thallium ions. The moles of peroxide ions present in the sample will be,
= 2.45 × 3 / 2
= 3.675 moles.
Hence, the moles of peroxide ions present in the given sample is 3.675.
Given:
magnesium = 0.941 gram piece
Magnesium oxide= 1.560 grams
Formula:
(magnesium / magnesium oxide) x 100 = % Mg
100% - % Mg = percent composition of each element
Solution:
(0.941g Mg) / (1.560g MgO)
= 0.603
= 60.3% Mg
100% - 60.3%
= 39.7%
39.7% is the percentage composition of each element.
Answer:
The advantage of net ionic equations is that they show only those species that are directly involved in the reaction
