If a gas at 20.0 °C occupies 3.60 liters at a pressure of 1.00 atm, what will be its volume at a
pressure of 2.50 atm? 1.44L

Answers

Answer:

1.44L

Explanation:

P1V1/T1=P2V2/T2

since the temperature didn’t change, stay at 20celsius, we can ignore T1 and T2.T1=T2

(1.00atm)(3.60L)=(2.50 atm)V2

V2=(1.00atm)(3.60L)/(2.50atm)

=1.44L

The main need or want the wave technology shown meets to see objects surrounding more clearly.

What is wave technology ?

It is a floating device that operates in the same direction as the waves. With the use of the technology, energy may be captured even from relatively small waves. The device that is moved by waves activates a hydraulic system that can power a generator. The tube segment contains all the generation equipment and systems.

Early mechanization (1770s to 1830s), steam power and railroads (1830s to 1880s), electrical and heavy engineering (1880s to 1930s), Fordist mass production (1930s to 1970s), and information and communication are the five waves that have so far slammed into our society (1970s to 2010s).

Wave energy, also known as wave power, is the energy that ocean surface waves carry and absorb. The energy is then put to use in a variety of productive ways.

Thus, The main need or want the wave technology shown meets to see objects surrounding more clearly.

Reacts with water to produce OH- ions.

This applies to:


Acids


Bases


Neutral solutions


Both Acids and Bases

Answers

Answer:

Bases

Explanation:

According to a Swedish scientist called Svante Arrhenius, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution i.e. when dissolved in water.

For example, sodium hydroxide (NaOH) will dissolve in water and dissociate into the following;

NaOH (aq) → Na+ (aq) + OH- (aq).

Hence, according to this question, the reaction with water to produce OH- ions is only applicable to BASES in accordance to Arrhenius definition.

A graduated cylinder was filled with 25.0 mL of water. A solid object was immersed in the cylinder, raising the water level to 32.9 mL. The volume of the object was calculated as 7.9 mL. The solid has a mass of 69.2 grams. What is the density of the object?

Answers

Answer:

Density of the object is 8759.494 grams/L

Explanation:

As we know density of an object is mass of the object divided by its volume

Given

Volume of the object is equal to the change in volume of water with in the cylinder when the object was immersed in water.

Hence, volume of object is equal to

[tex]32.9 -25 = 7.9[/tex] mL

Mass of the object is [tex]69.2[/tex] grams

Density

when silver is mixed with aluminum nitrate the products are silver nitrate and aluminum metal. how many molocules of silver nitrate are produced if we have 216 grams of aluminum nitrate?

STOICHIOMETRY

Answers

Answer:Aluminum metal in silver nitrate ….

You might be expecting silver metal, Ag, and aluminum nitrate, Al(NO3)3, as products. But instead all you will end up with is wet aluminum. The passivating layer of Al2O3 will prevent aluminum from reducing silver ions.

Explanation: Al(s) + AgNO3(aq) → No reaction

The two things we might do to the mixture to disrupt the Al2O3 surface will cause the Ag+ ions to react. Often a source of chloride ion is used because AlCl4^- will form, exposing the aluminum surface. But that will cause AgCl(s) to precipitate. You can also make the solution basic with NaOH and form Al(OH)4^-, but that will cause Ag2O(s) to form. (You will get Ag2O instead of AgOH.)

Concentrated acids will oxidize any aluminum metal that might be exposed if you were to add concentrated HNO3. That would simply enhance the

Workers who build railway tracks often use a process called thermite welding to connect pieces of track. Thermite is a mixture of aluminum metal (Al) and ferric oxide (Fe2O3). A worker places thermite between two pieces of track and then burns it to form aluminum oxide (Al2O3) and iron (Fe). As the reaction happens, the air around the mixture becomes so hot that the two pieces of track fuse together.

I need help some plz and don’t give me no virus or some fake answer I really need help

Answers

Answer:

1.) The possible genotypes are FF and Ff

The phenotype is full pod shape

2.) The possible genotypes are GG, Gg, and gg

The photypes are Green (for those whose genotype is GG and Gg) and yellow ( For those whose genotype is gg)

Explanation:

My hand writting isn't the best so I'll also type it.

1.) There are only 2 possible genotypes the offspring can have which are FF or Ff.

Because the dominant allele is F all the offspring from this cross will have a full pod shape phenotype.

2.) There are only 3 possible genotypes the offspring can have which are GG, Gg, and gg.

The majority of the offspring will have a green phenotype while the remainder will be yellow. G is the dominant allele so any offspring with the genotype GG or Gg will be green. While g is a recessive allele and only offspring who has a genotype of gg will be yellow.

*On my paper for question 2 for the phenotype explination I accidently wrote genotype instead of phenotype.

*Another note is that an offspring must have both recessive alleles in order to show the recessive traits. That is why gg is yellow and Gg is green.

What is the % dissociation of a solution of acetic acid if at equilibrium the solution has a pH = 4.74 and a pKa = 4.74?

Answers

Answer:

[tex]\% diss = 50\%[/tex]

Explanation:

Hello there!

In this case, when considering weak acids which have an associated percent dissociation, we first need to set up the ionization reaction and the equilibrium expression:

[tex]HA\rightleftharpoons H^++A^-\\\\Ka=\frac{[H^+][A^-]}{[HA]}[/tex]

Now, by introducing x as the reaction extent which also represents the concentration of both H+ and A-, we have:

[tex]Ka=\frac{x^2}{[HA]_0-x} =10^{-4.74}=1.82x10^{-5}[/tex]

Thus, it is possible to find x given the pH as shown below:

[tex]x=10^{-pH}=10^{-4.74}=1.82x10^{-5}M[/tex]

So that we can calculate the initial concentration of the acid:

[tex]\frac{(1.82x10^{-5})^2}{[HA]_0-1.82x10^{-5}} =1.82x10^{-5}\\\\\frac{1.82x10^{-5}}{[HA]_0-1.82x10^{-5}} =1\\\\[/tex]

[tex][HA]_0=3.64x10^{-5}M[/tex]

Therefore, the percent dissociation turns out to be:

[tex]\% diss=\frac{x}{[HA]_0}*100\% \\\\\% diss=\frac{1.82x10^{-5}M}{3.64x10^{-5}M}*100\% \\\\\% diss = 50\%[/tex]
