15. If you dilute a 6 M solution of HCl from 5 mL to 50mL, what is the concentration of this new solution? (M1V1 = M2V2)
A) 1.6 M
B) 0.6 M
C) 8.6 M
D) 0.006 M

Answers

Answer:

B) 0.6M

Explanation:

               I apologize in advance if it is not correct :l

The (M1V1= M2V2) is given for you to plug in the correct numbers so let's jot this down.

                    (M1*V1= M2*V2)

so they give us 6M which would be our (M1), from this we can also conclude that 5mL is also V1; ( if you notice the M1's and V1's are always found next to eachother). This leads us to our 50mL, this would be our V2 because the volume went from 5mL to 50mL. Now lets put this in order based on what we know.

M1= 6M                                (M1*V1= M2*V2)

V1= 5mL

M2= ?

V2= 50mL

now we plug in what we know into the equation to find the unknown (M2)

                   (6M*5mL= M2*50mL)

now we could do the long math, but I don't think your on brainly to do the hard way. so lets keep it simple!

                   We are going to put the 50mL under the (6M*5mL) for division.

                             [tex]\frac{(6M*5mL)}{(50mL)}[/tex] This is honestly MUCH easier, than manually answering. you just put that in the calculator and it'll give you B) 0.6M

                 

   honestly though I might not know what I'm doing cuz im currently doing my test and decided to answer this question ;)

        Good Luck!

Suppose that the student took one more volume
reading of 24.2 mL but forgot to measure the
pressure.
Compute the pressure expected for that
volume. kg/cm2?

Answers

Answer:

2.13 Kg/cm².

Explanation:

We'll begin by calculating the constant that exist between the pressure and the volume. This can be obtained by using the Boyle's law equation as shown below.

Boyle's law states that

PV = K

Where

P is the pressure.

V is the volume.

K is the constant.

We shall determine the value of K as follow:

Pressure (P) = 1.15 Kg/cm²

Volume (V) = 44.8 mL

Constant (K) =?

PV = K

1.15 × 44.8 = K

K = 51.52 Kg/cm²•mL

Finally, we shall determine pressure, when the volume is 24.2 mL. This can be obtained as follow:

Volume (V) = 24.2 mL

Constant (K) = 51.52 Kg/cm²•mL

Pressure (P) =?

PV = K

P × 24.2 = 51.52

Divide both side by 24.2

P = 51.52 / 24.2

P = 2.13 Kg/cm²

Therefore, the pressure is 2.13 Kg/cm².

Que representa en la reacción química
Na2SO4(s)+H2O(1)=

Answers

Answer: The given reaction is a double displacement reaction.

Explanation:

A chemical reaction equation in which both positive and negative ions of two different reactants are exchanged then it is called a double displacement reaction.

For example, [tex]Na_{2}SO_{4} + H_{2}O \rightarrow H_{2}SO_{4} + Na_{2}O[/tex]

Here, hydrogen ions of [tex]H_{2}O[/tex] are replaced by the sodium ions of [tex]Na_{2}SO_{4}[/tex]. Also, sulfate ion of [tex]Na_{2}SO_{4}[/tex] are replaced by oxygen ion of [tex]H_{2}O[/tex].

Thus, we can conclude that the given reaction is a double displacement reaction.

What is the mass of 1.72 moles of sodium nitrate? Use the periodic table and the polyatomic ion resource.

Answers

Answer:

[tex]\boxed {\boxed {\sf 146 \ g \ NaNO_3}}[/tex]

Explanation:

To convert from moles to mass, the molar mass is used. This tells us the grams in 1 mole of a substance.

1. Write Formula

We know the compound is sodium nitrate.

Sodium: NaNitrate: NO₃

Sodium has an oxidation state of +1 and nitrate's is -1. When they bond, sodium gives an electron to nitrate and the charges balance out. We don't need to add any additional subscripts.

Sodium nitrate: NaNO₃

2. Calculate Molar Mass

The molar mass is found on the Periodic Table. It is the same as the atomic mass, but the units are grams per mole. Look up the values for the individual elements.

Na:  22.9897693 g/mol N: 14.007 g/mol O: 15.999 g/mol

Notice that in the formula, oxygen has a subscript of 3. We must multiply oxygen's molar mass by 3 before adding the other molar masses.

O₃: 3(15.999 g/mol)= 47.997 g/molNaNO₃= 22.9897693+14.007+ 47.997 = 84.9937693 g/mol

3. Calculate Mass

Use the molar mass as a ratio.

[tex]\frac {84.9937693 \ g \ NaNO_3}{1 \ mol \ NaNO_3}[/tex]

Multiply by the given number of moles: 1.72

[tex]1.72 \ mol \ NaNO_3 *\frac {84.9937693 \ g \ NaNO_3}{1 \ mol \ NaNO_3}[/tex]

The units of moles of sodium nitrate cancel.

[tex]1.72*\frac {84.9937693 \ g \ NaNO_3}{1}[/tex]

[tex]146.1892832 \ g \ NaNO_3[/tex]

4. Round

The original measurement of moles has 3 significant figures, so our answer must have the same. For the number we found, that is the ones place.

146.1892832

The 1 in the tenths place tells us to leave the 6.

[tex]146 \ g \ NaNO_3[/tex]

1.72 moles of sodium nitrate has a mass of approximately 146 grams.

In earthquake-prone areas, engineers design buildings that are resistant to earthquake damage. Here’s a diagram of an earthquake-resistant building in Japan. Explain how features A, B, and C help protect the building from earthquake damage. In your explanation, describe how you could model each feature using marshmallows and toothpicks.

Answers

Answer:

In this earthquake-resistant building, two steel supports in the shape of an X (A) help to reinforce walls. Concrete walls with steel bars in them (B) lessen any rocking movements. Shock absorbers (C) take up some of the building’s kinetic energy during a quake. I could use the toothpicks as the two steel in the shape of an X. The concrete walls and the shock absorbers would be the marshmallows.

Features shown by points A, B & C are reinforce walls, concrete walls and shock absorbers respectively.

What is earthquake?

Earthquake is a kind of natural disaster in which an intense shaing of the earth's outermost layer takes place.

According to the image following points we will consider as:

Two steel supports in the shape of an X (A) help to reinforce walls in this earthquake-resistant structure.Any rocking movements are reduced by concrete walls with steel bars (B).During a quake, shock absorbers (C) absorb some of the kinetic energy of the building.

We can use the toothpicks in the shape of X as the two steel and concrete walls & the shock absorbers as the marshmallows.

Hence, marshmallows are used as the concrete walls and toothpicks are used as two steel rods.

what mass of O2 is needed to completely react with 500 g of Fe

Explanation:

4Fe +3O2------------>2Fe2O3

4mole. 3mole. 2 mole

224g. 96g. 320g

we have

224 g of fe needed to react completely with 96 g of O2

500g of fe needed to react completely with

96 ×500/224=214.3g of O2

214.3g of O2 is a required answer.

"The mass of [tex]O_{2}[/tex]  will be 214.3g to completely react with 500 g of Fe."

What is mass?

A physical body's mass is the amount of matter it contains. It can  also use to measure  moment of inertia, or the resistance to movement when one net force is exerted. The degree of an object's gravitational pull to other bodies is also determined by its mass. The kilogram is the SI base unit of mass.

The reaction between Fe and [tex]O_{2}[/tex] can be written as:

[tex]4Fe+3O_{2}[/tex] → [tex]2Fe_{2}O_{3}[/tex]

It can be see that 4 mole of iron is reacts with 2 mole of oxygen and its form 2 mole of [tex]2Fe_{2}O_{3}[/tex]

So, 224 g of iron is needed in the reacted with oxygen (96 g).

500 g of iron will be needed = 96× 500/224= 214.3g of  [tex]O_{2}[/tex].

Predators decreased, food source increased, migration patterns, natural disaster or threat in normal habitat.

The reason behind an increased population of any organism is a lack of predators, favorable habitat, good food source.

What are jellyfishes?

Jellyfishes are umbrella-shaped, free-living marine animals.

They have long tentacles which are highly dangerous.

They are not true fishes.

The reasons for the increase in the number of organisms in an area:

Predators are animals who eat another small animal for their survival. If there is less number of predators of any organism, their population increase.

Favorable environmental conditions are another reason for the population increase of a population.

Food availability.
