Answer: It is a Lewis acid/base reaction, and
is the Lewis acid.
Explanation:
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
can readily accept electrons and thus act as a lewis acid which is short of electrons.
can readily lose electrons and thus act as a lewis base which has excess of electrons.
It is a Lewis acid/base reaction, and
is the Lewis acid.
Answer:
we will take a 100g sample of this solution for our convenience
so , there is 15 g kBr in this 100g solution
we know that molality is the number if moles of solute / mass of solvent in kg
we need to find the number of moles in 15g kBr
no of moles = 15/119 s
moles = 0.126 moles/ 100g
multiplying both the numerator and the denominator by 10 to get 1 kg in denominator
= 1.26 moles / 1 kg
Hence, the molality is 1.26
would appreciate a brainliest
if all sides are unequal it is scalene and if one angle adds up to 90 while the rest are different youve proven it.
Answer:
The answer is
<h2>155 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of bromine = 50 mL
density = 3.10 g/cm³
It's mass is
mass = 50 × 3.10
We have the final answer as
<h3>155 g</h3>

Answer:
Concentration of Ca(OH)₂:
0.117 M.
Explanation:
How many moles of HCl is consumed?
Note the unit of concentration: moles per liter solution.
.
Convert milliliters to liters.
.
.
How many moles of NaOH in the solution?
Refer to the equation. The coefficient in front of Ca(OH)₂ is 1. The coefficient in front of HCl is 2. In other words, it takes two moles of HCl to neutralize one mole of Ca(OH)₂. That
of HCl will neutralize only half that much Ca(OH)₂.
.
What's the concentration of the Ca(OH)₂ solution?
Concentration is the number of moles of solute per unit volume.
.
