<h3>Answer:</h3>
Option-B (Halide; oxide) is the correct answer.
<h3>Explanation:</h3>
<em> Halides</em> are those substances which contains negatively charged halide ion i.e. X⁻.
Examples: F⁻ (Fluoride) , Cl⁻ (Chloride) , Br⁻ (Bromide) , I⁻ (Iodide) e.t.c.
<em>Oxides </em>are those substances which atleast containn one Oxygen atom.
Examples: FeO (Iron Oxide), Cr₂O₃ (Chromium Oxide)
<em>Silicates</em> are those anionic substances which contains silicon and oxygen with general formula [SiO. 4−x] n.
Examples: [SiO₄]⁻⁴ (Nasosilicate) , [Si₂O₇]⁻⁶ (Sorosilicates)
<em>Carbonates </em>are those substances which contains carbonate anion i.e. CO₃²⁻.
Examples: Na₂CO₃ (Sodium Carbonate) , MgCO₃ (Magnesium Carbonate)
<h3>Conclusion:</h3>
As in NaCaAlF, F⁻ is present hence, it is an Halide and the presence of O in FeCrO makes it Oxide.
Answer:
222.2 grams of CaCl2 in 2 moles
Explanation:
Mole=given mass/gram mass formula
2moles=x/Gram Mass Formula
(Gram Mass Formula of CaCl2):
Ca=40.1
Cl= 35.5 x 2= 71
-----------------------
GFM=111.1
2 moles = x/111.1 g
x=222.2
Answer:
Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The mixture of oil and water forms two separate layers because they are completely insoluble in each other.
It loses an H+.
The bronsted lowry definition for an acid is that an acid is a H+ donor, or giver. So, during an acid based reaction, an acid would lose a H+.
Lose an H+.
