Answer:
12.044 ×10²³ molecules of HCl
Explanation:
Given data:
Number of moles of MgO = 1 mol
Number of molecules of HCl react = ?
Solution:
Chemical equation:
MgO + 2HCl → MgCl₂ + H₂O
with 1 mole of MgO 2 moles of HCl are react.
Number of molecules of HCl react:
1 mole contain 6.022×10²³ molecules
2 mol × 6.022×10²³ molecules / 1 mol
12.044 ×10²³ molecules
Answer:
A decompositon reaction is a reaction that takes place when one reactant breaks down into two or more simpler substances. The decomposition reaction can be represented by the general equation: AB → A + B. Most of the decomposition reactions require an input of energy in the form of heat, light or electricity
Explanation:
Answer:
F-Cl , O-H , N-S
Explanation:
Polarity of a bond is determined by the Electronegativity across the period and its group.
So un the basis of that.
A .Br - Cl < F-Cl
B .O-H > Se-H
C .As-H < N-S
