<h2>Express 0.05 grams in kilograms, using the correct abbreviations.</h2>

Explanation:

Mass

It is the quantity of matter contained in the body .

Mass = quantity of matter

Its unit is : Kilogram (Kg)

Other unit =Gram (g)

The relation between kilogram and gram is :

1Kg=1000g

So, if we have to convert gram into kilogram , we have to divide the given value by 1000.

If we have to convert kilogram to gram , we have to multiply the given value by 1000.

In the above asked question ,convert 0.05g to kilogram

1g=1/1000kg

so,0.05g=------kg

that is :

0.05 /1000=0.00005Kg

What is the formula of arsenic hexabromide?
Nady [450]
When dealing with compounds and their names, it helps to know the prefixes of some of the common compounds. For instance,

Mono- = 1
Di- = 2
Tri- = 3
Tetra- = 4
Penta- = 5
Hexa- = 6

And the list goes on.

However we are dealing with Arsenic Hexabromide:

That means we have 1 Arsenic with 6 Bromides:

What is a maximum negative displacement of a wave
AnnZ [28]

The maximum negative displacement of a wave is the same as its amplitude.

As a wave travels through space, its particles are sometimes above the

<em>x</em>-axis (+) and sometimes below it (-).

The maximum displacement from the axis is the <em>amplitude</em> of the wave.

The amplitude of the wave is the <em>same in both the positive and negative directions</em>.

The pH of a 0.23M solution of acrylic acid HC3H3CO2 is measured to be 2.44. Calculate the acid dissociation constant Ka of acryl
belka [17]

Answer:

Kₐ =  5.7 x 10⁻⁵

Explanation:

The equilbrium for this acid is

HC₃H₃CO₂ + H2O    ⇄ H₃O⁺  +   C₃H₃CO₂ ⁻  ,

and the equilibrium constant for acrylic acid is given by the expression:

Kₐ = [ H₃O⁺][ C₃H₃CO₂⁻ ] / [ HC₃H₃CO₂ ]

Since  the pH of the 0.23 M solution is known , we can calculate [ H₃O⁺].

The ][ C₃H₃CO₂⁻ ]  is equal to  [ H₃O⁺] from the above equilibria (1:1)

Finally [ HC₃H₃CO₂ ] is known.

pH = - log  [ H₃O⁺]

taking antilog to both sides of the equation

10^-pH =  [ H₃O⁺]

Substituting

10^-2.44 =  [ H₃O⁺]  = 3.6 x 10⁻³

[ C₃H₃CO₂⁻ ] = 3.6 x 10⁻³

Kₐ = ( 3.6 x 10⁻³ ) /0 .23 = 5.7 x 10⁻⁵
