18. Describe cementation

Answers

Cementation is a type of precipitation, a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface. ... Cementation of copper is a common example. Copper ions in solution, often from an ore leaching process, are precipitated out of solution in the presence of solid iron.

Wikipedia
Depends on what you are looking for

Cementation is the binding together of particles or other things by cement.

Cementation, in geology, is hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock.

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.

A chemist must prepare 575.mL of 1.00M aqueous sodium carbonate Na2CO3 working solution. He'll do this by pouring out some 1.58M aqueous sodium carbonate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the sodium carbonate stock solution that the chemist should pour out. Round your answer to 3 significant digits.

Answers

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.

What volume of carbon dioxide gas at STP is required to produce 456.9g of lithium carbonate? PLEASE EXPLAIN HOW YOU GOT THE ANSWER

Answers

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

A substance joined by this type of bond will conduct electricity when in?​

Answers

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.

2. A quantity of 1.922g of methanol (CH3OH) was burned in a constant-volume
bomb calorimeter. Consequently the temperature of the water rose by 4.20C.
If the heat capacity of the bomb plus water was 10.4KJ/C, calculate the molar
heat of combustion of methanol.

Answers

Mass of methanol (CH3OH) = 1.922 g
Change in Temperature (t) = 4.20°C
Heat capacity of the bomb plus water = 10.4 KJ/oC
The heat absorbed by the bomb and water is equal to the product of the heat capacity and the temperature change.
Let’s assume that no heat is lost to the surroundings. First, let’s calculate the heat changes in the calorimeter. This is calculated using the formula shown below:
qcal = Ccalt
Where, qcal = heat of reaction
Ccal = heat capacity of calorimeter
t = change in temperature of the sample
Now, let’s calculate qcal:
qcal = (10.4 kJ/°C)(4.20°C)
= 43.68 kJ
Always qsys = qcal + qrxn = 0,
qrxn = -43.68 kJ
The heat change of the reaction is - 43.68 kJ which is the heat released by the combustion of 1.922 g of CH3OH. Therefore, the conversion factor is:

Write the following elements in decreasing ionic size. Li+, C4+, F-, O2-

70 POINTS

Answers

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.

What is the probability of having major earthquakes or volcanoes occur in New York State?

Answers

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.

What is earthquakes ?

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.

Is it easier for an atom to lose a proton or a neutron?why or why not

will brain list

Answers

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.

25.1 g express as an integer

Answers

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:

0.028578 km

Explanation:

The following data were obtained from the question:

Length of whale (in mm) = 28578 mm

Length of whale (in km) =?

We can convert 28578 mm to km by doing the following:

Recall:

1 mm = 1×10¯⁶ Km

Therefore,

28578 mm = 28578 mm × 1×10¯⁶ Km / 1 mm

28578 mm = 0.028578 km

Thus, 28578 mm is equivalent to 0.028578 km

The length of whale (in km) = 0.028578 km

1. Calculate the mass of the product, if you started with 4 g of Zn and 3 g of H2CO3.
Zn + H2CO3
ZnCO2 + H2 * I’ll cash app for the right answer plus explanation”

Answers

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.
