The reaction will produce lead chloride PbCl₂ and aluminium nitrate Al(NO₃)₃.

Explanation:

Aluminium chloride will react with lead nitrate to produce the aluminium nitrate and the lead chloride which is poorly soluble in water.

2 AlCl₃ (aq) + 3 Pb(NO₃)₂ (aq) → 2 Al(NO₃)₃ (aq) + 3 PbCl₂ (s)

where:

(aq) - aqueous

(s) - solid

First, let's start off by finding the mass of this whole hydrate.
(Note: the unit of measurement for mass will be amu)

Let's find the molecular mass of each element.
$Co=58.933$
$Cl=35.45$
$H=1.008$
$O=15.999$

Now, let's find the mass of each compound.

$CoCl_2=58.933+2(35.45)=129.833$
$H_2O=2(1.008)+15.999=18.015$

We have 6 molecules of H2O, so multiply 18.015 by 6 then add that with the weight of CoCl2.

$6(18.015)=108.09$
$129.833+108.09=237.923$

Now divide 108.09 (mass of all the H2O in the hydrate) by 237.923 (total mass of hydrate).

$\dfrac{108.09}{237.923}$

$\approx0.45431$

Turn that into a percentage and you get 45.431%.
Hope this helps! :)

Jonathan claims that since only humans can read, it must be an inherited trait, passed from human parents to their children. Is

Crank

Jonathan is not correct because it has to be a trait that is learned.

So in that case Jonathan has to say that this is not an inherited trait it is learned by most people.

What is the amplitude of the above wave?

Alinara [238K]

Answer:Amplitude in a longitudinal wave

Explanation:Wave amplitude of a longitudinal wave is the distance between particles of the medium where it is compressed by the wave. Wave amplitude is determined by the energy of the disturbance that causes the wave. A wave caused by a disturbance with more energy has greater amplitude.

Describe where the "Reference Carbon" (the one that determines if the structure is D or L) is located in a carbohydrate with mor

tresset_1 [31]

Answer:

Farthest from the carbonyl carbon.

Explanation:

Reference carbon that determined the absolute D and L configuration is located farthest from the carbonyl carbon.

In other words, reference carbon is that assymentric carbon which is located farthest from the carbolyl carbon and has configuration similar to D- or L-glyceraldehyde isomers.

D and L configuration is decided by the direction of -OH group attached to the reference carbon.

In L-isomer, -OH group is attached to the left side of the reference carbon and in D-isomer, -OH group is attached to the right side of the reference carbon.
