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

Answer:

The answer is offspring

Explanation:

Answer:

you didn't specify what the presentation was about. However, I can help you by showing you how to do this activity.

When making notes of the sources, you must show when these sources were built and what is their direct relationship with your research, in addition to highlighting the concepts and parts you will use in your presentation. It is also important that you show the connection between the sources, that is, how they come together to collaborate for your presentation. We must not forget that you must have different sources, that is, different media, such as websites, books, magazines, interviews, videos, among others.

After you have highlighted which parts of the sources you will use in the presentation, you should reread those parts and make topics about which point of those parts will be used in your presentation, that is, you must show the most revealing points, those to which you won't talk about.

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.

Answer: The staircase is 14.28 m high.

Explanation:

Given : Mass = 0.1 kg

Potential energy = 14 J

Potential energy is the energy occupied by the position of a substance. Therefore, formula for potential energy is as follows.

P.E = mgh

where,

m = mass

g = gravitational energy = [tex]9.8 m/s^{2}[/tex]

h = height of object

Substitute the values into above formula as follows.

[tex]P.E = m \times g \times h\\14 J = 0.1 kg \times 9.8 m/s^{2} \times h\\h = \frac{14 J}{0.1 kg \times 9.8 m/s^{2}}\\= \frac{14 J}{0.98 m kg/s^{2}}\\= 14.28 Js^{2}/ mkg (1 J s^{2}/m kg = 1 m)\\= 14.28 m[/tex]

Thus, we can conclude that the staircase is 14.28 m high.

PS. Can I have Brainliest?

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

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]

Explanation:

HNO3(aq) is the compound produced by a neutralization

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

[tex]= \frac{69.2}{7.9 *10^{-3}}\\= 8759.494[/tex] grams/L

Density of the object is 8759.494 grams/L

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.
