How many grans of NaoH Are needed to neutralize grans of H2So4

A sample of an unknown liquid has a volume of 24.0 mL and a mass of 6 g. What is its density? Show your work or explain how you

kobusy [5.1K]

The answer would be 0.25 g/mL.
I determined the density by dividing the mass by the volume which gives you the density. D = mass/volume.
6 g / 24 mL = 0.25 g/mL

"Compounds A and B react to give a single product, C. Write the rate law for each of the following cases and determine the units

olasank [31]

Answer:

Part a: Units of k is $M^{-2}s^{-1}$ where reaction is first order in A and second order in B

Part b: Units of k is $M^{-1}s^{-1}$ where reaction is first order in A and second order overall.

Part c: Units of k is $M^{-1}s^{-1}$ where reaction is independent of the concentration of A and second order overall.

Part d: Units of k is $M^{-3}s^{-1}$ where reaction reaction is second order in both A and B.

Explanation:

As the reaction is given as

$A+B \rightarrow C$

where as the rate is given as

$r=k[A]^x[B]^y$

where x is the order wrt A and y is the order wrt B.

Part a:

x=1 and y=2 now the reaction rate equation is given as

$r=k[A]^1[B]^2$

Now the units are given as

$r=k[A]^1[B]^2\\M/s =k[M]^1[M]^2\\M/s =k[M]^{1+2}\\M/s =k[M]^{3}\\M^{1-3}/s =k\\M^{-2}s^{-1} =k$

The units of k is $M^{-2}s^{-1}$

Part b:

x=1 and o=2

x+y=o

1+y=2

y=2-1

y=1

Now the reaction rate equation is given as

$r=k[A]^1[B]^1$

Now the units are given as

$r=k[A]^1[B]^1\\M/s =k[M]^1[M]^1\\M/s =k[M]^{1+1}\\M/s =k[M]^{2}\\M^{1-2}/s =k\\M^{-1}s^{-1} =k$

The units of k is $M^{-1}s^{-1}$

Part c:

x=0 and o=2

x+y=o

0+y=2

y=2

Now the reaction rate equation is given as

$r=k[A]^0[B]^2$

Now the units are given as

$r=k[B]^2\\M/s =k[M]^2\\M/s =k[M]^{2}\\M^{1-2}/s =k\\M^{-1}s^{-1} =k$

The units of k is $M^{-1}s^{-1}$

Part d:

x=2 and y=2

Now the reaction rate equation is given as

$r=k[A]^2[B]^2$

Now the units are given as

$r=k[A]^2[B]^2\\M/s =k[M]^2[M]^2\\M/s =k[M]^{2+2}\\M/s =k[M]^{4}\\M^{1-4}/s =k\\M^{-3}s^{-1} =k$

The units of k is $M^{-3}s^{-1}$

There are two different compounds of sulfur and fluorine.

Sedaia [141]

1.18 x 3 = 3.55 
find ratio of F to F in each compound
. according to law of multiple proportions that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers.
now F is "one element" and S has "fixed mass",
the ratio of F6 to Fx = 3:1
thats why x= 2
there is less F in SFx
the ratio is 3:1.
dividing 6 by 3 and you get 2

What is the Newman projection for Citric Acid?

Lana71 [14]

Answer:

A Newman projection, useful in alkane stereochemistry, visualizes the conformation of a chemical bond from front to back, with the front atom represented by a dot and the back carbon as a circle. The front carbon atom is called proximal, while the back atom is called distal.

Which combination of reactants will produce ethyl 3-phenyl-3-oxopropanoate when treated first with an alkoxide and then with a d

Nezavi [6.7K]

Ethyl acetate and methyl benzoate combination of reactants will produce ethyl 3-phenyl-3-oxopropanoate when treated first with an alkoxide and then with a diluted aqueous acid

<h3>Ethyl acetate</h3>

One of the most straightforward carboxylate esters is ethyl acetate. The simplest is methyl formate, a former Molecule of the Week. Most people enjoy the taste and aroma of the colorless liquid's sweet, fruity scent.

Ethyl acetate was initially created by combining ethanol and acetic acid, as one might anticipate. The process was the traditional Fischer esterification, which dates back to 1895 and is catalyzed by an acid. This commercial synthesis is still the most popular. A different approach is the Tishchenko reaction, in which acetaldehyde disproportionately reacts with base to form alcohol and acid, which subsequently esterify naturally.
