what type of bonding is occuring in the compound below?​

Answer:

212. 9 degree celcius

Explanation:

From PV =nRT

T= PV/nR

T= (5. 5x20)/(6. 3x0. 082)

T= 110/0. 5166

T= 212. 9 degree celcius

Answer:

Because in order to find the average, you need to divide by the number of sites tested. Sometimes that doesn't divide evenly.

Answer:

Option C, the shower not sprayed with any mildew-preventing spray is most likely be the control group in this  study

Explanation:

Complete question

Mildew is a fungus that grows in wet areas and can slowly grow from microscopic to large stains in showers and sinks. Researchers are studying different sprays that could be used to slow down the growth of mildew. They set up different showers that are exactly the same and expose them each to water with the same microscopic amount of mildew. They then spray some of the showers with mildew-preventing sprays and observe how fast mildew grows over time. Which show would most likely be the control group in this study? A- the shower sprayed with many test sprays B- the shower not exposed to any mildew at all C- the shower not sprayed with any mildew-preventing spray D- the shower sprayed with a test spray that is already known to work

Solution

In any experiment, a control group is a group of participants that is not exposed to any treatment so that it can be compared with the experimental group on which the treatment is applied/given.

In this case - experimental group are the stained showers that are subjected to the different types of mildew test sprays while the control group is the the shower not sprayed with any mildew-preventing spray.

Hence, option C is the correct answer

Answer:

b)6.2 grams

Explanation:

Recall that percentage yield =

actual yield/theoretical yield * 100/1

theoretical yield = 8.2 grams

percentage yield = 75%

Let the actual yield be x

Hence;

75 = x/8.2 * 100

75 = 100x/8.2

75 * 8.2 = 100x

x = 75 * 8.2/100

x = 6.15 g

x = 6.2 g

75 =

The answer is electrolysis

Answer: A reaction which occurs when equivalent quantities of H" (or [tex]H_{3}O^{+}[/tex]) and OH" are mixed is a neutralization reaction.

Explanation:

When acid and base chemically combine together to form sat and water then it is know as neutralization reaction.

An acidic substance gives hydrogen ions [tex](H^{+})[/tex] on dissociation and a basic substance gives hydroxide ions [tex](OH^{-})[/tex] on dissociation.

For example, [tex]H^{+} + OH^{-} \rightarrow H_{2}O[/tex] is a neutralization reaction where an acid and base are mixed together to form water.

No salt is formed as because here the reactants are not present as compounds.

In a hydrolysis reaction, water molecule(s) is added to the reactant molecules.

For example, [tex]CH_{3}COOCH_{3} + H_2O \rightarrow CH_{3}COOH + CH_{3}OH[/tex]

Oxidation is the process of addition of oxygen to a molecule and removal of hydrogen.

Reduction is the process of addition of hydrogen in a compound and the removal of oxygen atom.

Therefore, we can conclude that reaction which occurs when equivalent quantities of H" (or [tex]H_{3}O^{+}[/tex]) and OH" are mixed is a neutralization reaction.

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]

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:

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.

Explanation:

HNO3(aq) is the compound produced by a neutralization

Explanation:

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.
