Answer:
The appropriate speed will be "20 m/s".
Explanation:
The given values are:
Wavelength,
λ = 5.0 M
Frequency,
f = 4 Hz
Now,
The speed of the wave will be:
⇒
On putting the values, we get
⇒
⇒
chlorobenzene
Carbon - 6
Hydrogen - 5
Chlorine - 1
that 1 chlorine replaces one of the hydrogens
thats why hydrogen number decreases by number of Cl atoms (that are substituting those H atoms)
Answer:
The answer is
<h2>5.50</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 22 g
density = 4 g/mL
The volume is
We have the final answer as
<h3>5.50 mL</h3>
Hope this helps you
answer= 0.5
explanation=
Carbon has a relative atomic mass of 12.
Oxygen has a relative atomic mass of 16.
12+(2x16)=44
Therefore 1 mole of CO2 has a relative atomic mass of 44.
22/44=0.5, so there is half a mole of CO2 in 22g of it
