Answer:
Total mass of the compound:=18.20+2.45
=20.65
Percentage by mass of hydrogen:=2.45÷20.65×100
=11.86%
Explanation:
Just follow the steps i have provided above
Hey there!:
Detailed solution is shown below ask if any doubt :
Answer:
The amplitude of the sound wave in no way affects the speed of the sound as it affects the loudness of the sound produced. Loudness depends on the square of the amplitude of the wave. Amplitude is the size of the vibration, and this determines how loud the sound is. Larger vibrations make a louder sound.

Answer:
the acid strength is the order of > >
Explanation:
Given that :
a .
b.
c.
Acid strength is the ability of an acid to dissociate into a proton and an anion. Take for instance.
HA ↔ H⁺ + A⁻
The acid strength of the following compounds above are:
= 1.00 × 10⁻¹⁰
= 6.6 × 10⁻⁴
= 6.3 × 10⁻⁵
As the acid dissociation constant increases the relative acid strength also increases.
From above, the acid strength is the order of > >
, and F⁻ are Bronsted- Lowry acid
Bronsted- Lowry acid are molecule or ion that have the ability to donate a proton.
