Answer:

New York City is susceptible to at least a magnitude 5 earthquake once every 100 years.

Explanation:

The probability of having major earthquakes or volcanoes occur in New York State is at least, one magnitude 5 earthquake can occur in New York City once every 100 years.

When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.

Earthquakes often result from subsurface rock breaking unexpectedly and fast movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.

The Circum-Pacific Belt, often known as the Ring of Fire, is a region in the Pacific Ocean marked by active volcanoes and frequent earthquakes. The Ring of Fire is where most of Earth's earthquakes and volcanoes occur.

Thus, at least, one magnitude 5 earthquake can occur in New York City once every 100 years.

Answer : The volume in mL of the sodium carbonate stock solution is 364 mL.

Explanation :

According to dilution law:

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1[/tex] = molarity of aqueous sodium carbonate

[tex]M_2[/tex] = molarity of aqueous sodium carbonate stock solution

[tex]V_1[/tex] = volume of aqueous sodium carbonate

[tex]V_2[/tex] = volume of aqueous sodium carbonate stock solution

Given:

[tex]M_1[/tex] = 1.00 M

[tex]M_2[/tex] = 1.58 M

[tex]V_1[/tex] = 575 mL

[tex]V_2[/tex] = ?

Now put all the given values in the above formula, we get:

[tex]1.00M\times 575mL=1.58M\times V_2[/tex]

[tex]V_2=363.92mL\approx 364mL[/tex]

Therefore, the volume in mL of the sodium carbonate stock solution is 364 mL.

Answer:

As the temperature heats up then the viscosity is much higher, as defined in stress analysis and fluid mechanics. Reynolds number describes the speed and the inverse proportion.

Answer:

Newton's third law of motion states that every action, there is an equal and opposite reaction force and that forces come in pairs

Answer:

C.) If the solid is conductive, the bonds are metallic.

1) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.

2) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.

3) Substances with metallic  bond conduct an electric current in liquid and solid state, because they have mobile electrons. Most metals have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

The balanced equation :

4Fe + 3O₂⇒ 2Fe₂O₃

Given

Rust reaction

Required

Balanced equation

Solution

Reaction

Fe + O₂⇒ 2Fe₂O₃

For a simple equation where one of the reaction coefficients is known, we can immediately add the corresponding coefficient using the principle that the number of atoms of the components in the reactants and products is the same.

In the above reaction :

Fe, left=1, right = 4, so coefficient in the left=4

O, left=2, right = 6, so coefficient in the left=3

Answer:

X¹/⁴ Y¹/²

Explanation:

From the question given above, we are required to simplify:

⁸√(X²Y⁴)

The above expression can be simplified as follow:

⁸√(X²Y⁴)

Recall:

ⁿ√Aᵐ = Aᵐ/ⁿ

Therefore,

⁸√(X²Y⁴) = X²/⁸ Y⁴/⁸

⁸√(X²Y⁴) = X¹/⁴ Y¹/²

Thus, ⁸√(X²Y⁴) is equivalent to X¹/⁴ Y¹/²

The chemical formula for hydrogen phosphate​ is HPO₄²⁻

Answer:

25 g

Explanation:

Integers are positive or negative whole numbers together with zero. This definition implies that 25.1 g is not an integer.

Seeing that .10 is less than .50, we have to round 25.10 down to 25.

Hence, if i express 25.10g as an integer, i end up with 25 g

Answer:

V =  138.68 L

Explanation:

Given data:

Volume of CO₂ at STP required = ?

Mass of lithium carbonate produced = 456.9 g

Solution;

Chemical equation:

2LiOH + CO₂     →     Li₂CO₃ + H₂O

Number of moles of Li₂CO₃ produced:

Number of moles = mass/molar mass

Number of moles = 456.9 g/ 73.89 g/mol

Number of moles = 6.184 mol

now we will compare the moles of Li₂CO₃ with CO₂ from balanced chemical equation to get number of moles of CO₂  reacted.

                      Li₂CO₃      :        CO₂

                           1           :          1

                         6.184     :        6.184

Thus, 6.184 moles of  CO₂ reacted.

Volume of CO₂:

PV = nRT

R = general gas constant = 0.0821 atm.L /mol.K

1 atm × V = 6.184 mol ×0.0821 atm.L /mol.K × 273.15 K

V = 138.68 atm.L / 1 atm

V =  138.68 L

Answer:

6.07 g.

Explanation:

Hello!

In this case, given the chemical reaction:

[tex]Zn + H_2CO_3 \rightarrow ZnCO_3 + H_2[/tex]

We first need to compute the moles of each reactant considering their molar masses:

[tex]n_{Zn}=4gZn*\frac{1molZn}{65.38 gZn} =0.0612molZn\\\\n_{H_2CO_3}=3gH_2CO_3*\frac{1molH_2CO_3}{62.03 gH_2CO_3} =0.0484molH_2CO_3[/tex]

Now, compute the mass of zinc carbonate yielded by each reactant in order to pick out the correct limiting reactant:

[tex]n_{ZnCO3}^{by\ Zn} = 0.0612molZn*\frac{1molZnCO3}{1molZn}*\frac{125.4 gZnCO3}{1molZnCO3}=7.67gZnCO3 \\\\n_{ZnCO3}^{by\ H_2CO3} = 0.0484molH_2CO3*\frac{1molZnCO3}{1molH_2CO3}*\frac{125.4 gZnCO3}{1molZnCO3}=6.07gZnCO3[/tex]

Thus, we conclude carbonic acid is the limiting reactant as it produces the fewest grams of product and therefore the yielded mass of zinc carbonate product 6.07 g.

Answer:

Li+, C4+, O2-, and then F- They're written in decreasing ionic size.

Explanation:

Ionic size means the same thing as ionic radius.  Furthermore, Ionic radius is the distance away from the central atom. Ionic radius increases going from top to bottom and decreases across the periodic table.

Lithium is in the 1st family/group with a charge of +1.  So it has the biggest ionic radius.

Carbon is in the 4th family/group with a charge of +4. So it has a smaller ionic radius than Lithium.

Oxygen is in the 6th family/group with a charge of -2.  So it has a smaller ionic radius than Carbon.

Lastly, Fluorine is in the 7th family/group with a charge of -1. So it has a smaller ionic radius than Oxygen.

In this case, since the average rate of reaction is computed as a change given by:

[tex]r=\frac{\Delta [NH_4NO_2 ]}{\Delta t}[/tex]

In such a way, given the concentrations at the specified times, we plug them in to obtain:

[tex]r=\frac{(1.48M-4.12M)}{(330s-250s)}\\\\r=-0.033\frac{M}{s}[/tex]

Answer:

No

Explanation:

It is not easier for an atom to lose a proton or a neutron because these particles are held together by very strong nuclear forces within the atom.

Protons are positively charged particles

Neutrons do not carry any charges.

  In the nucleus of an atom, both protons and neutrons can be found.

As with both particles, the very strong attractive force makes them very difficult to remove in ordinary chemical reactions.

Nuclear forces are one of the strongest forces that keeps an atom especially the nucleus together. Only in nuclear reactions to we encounter a situation where nuclear materials are changed, in that regard the properties of the atom also changes.

Answer:

Density

Explanation:

Density is defined as the mass per unit volume. It is the ratio between the mass and the volume of a substance. It does not matter how large or small a sample of matter is, the same substance will always have the same density, because of this. The ratio between the mass and volume remains the same.
