A wave is a ______ that carries ______ from one place to another?. ​

Answer:

corrosion resistance.

Explanation:

In summary, stainless steel does not rust because it is sufficiently reactive to protect itself from further attack by forming a passive corrosion product layer. (Other important metals such as titanium and aluminum also rely on passive film formation for their corrosion resistance.)

Answer:

[tex]8.314\ \text{m}^3\text{Pa/mol K}[/tex]

Explanation:

Let us find the unit of the gas constant R from the ideal gas equation. We substitute the units of the quantities rearrange them and get the units of the gas constant.

P = Pressure = Pa

V = Volume = [tex]\text{m}^3[/tex]

n = Moles = mol

T = Temperature = K

[tex]PV=nRT\\\Rightarrow R=\dfrac{PV}{nT}\\\Rightarrow R=\dfrac{\text{Pa m}^3}{\text{mol K}}[/tex]

Here, [tex]\text{Pa}[/tex] is used so the gas constant value that must be used is [tex]8.314\ \text{m}^3\text{Pa/mol K}[/tex].

The factor that would help to determine the distance of the ship from the fish would be  The amount of time it takes the sound waves to travel to the fish and back to the boat​.

This is the term that is used to refer to the total distance that would be traveled by a wave in a given cycle. The distance is usually calculated by the use of lambda. The use of Sonar would have to be determinant on the sound that is being heard.

We would have to check the way that the sound would have to come from the ship and then the way that it would have to be go back to the given boat that is used to report and find the school of fisn.

Hence we would say that The factor that would help to determine the distance of the ship from the fish would be  The amount of time it takes the sound waves to travel to the fish and back to the boat​.

False, the independent variable goes on the bottom

The statement “In a graph, the independent variable will always go on the side.” is false. The correct option is B.

A graph is a simple way of representing data. It shows the relation between two or more data with lines, numbers, and charts. The mathematical graphs are of different types. Mainly, a graph has a line and an x-axis and y-axis.

The x-axis contains the independent variable, which is written n the bottom of the graph, horizontally. The y-axis contains the dependent variable, which is written on the left side of the graph vertically.

The independent variable change, but the dependent variable do not change. It is the input. The independent variable changes with the time or what is written on the dependent variables.

Thus, the correct option is B. False.

Answer:

0.71 g/mL

The liquid is diethylamine

Explanation:

Mass of the liquid = 1.23 kg of 1.23 * 10^3 g

Volume of the liquid = 1737.cm3

Let us remember that density is obtained as;

Density= mass/volume

Density= 1.23 * 10^3 g/1737cm^3

Density= 0.71 g/cm^3

Since we know that 1 mL=1 cm3 . So, 1 g/mL=1 g/cm3

So we can also write;

Density= 0.71 g/mL

The liquid is diethylamine

Answer:

Explanation:

Diamond has lesser density than platinum . So , if we take equal mass of both , the volume of mass of platinum will be far less .

The density of both diamond and platinum are  more than water so both of them will be drowned in water completely . They will not float . On being drowned , platinum will displace lesser volume of water because of its less volume . So volume change in case of platinum mass will be far less . The volume change for diamond will be more because of its bigger size.

Answer:

Which atom is oxidized in the reaction of benzhydrol with bleach?

Explanation:

n this experiment, students will perform a simple oxidation reaction of a secondary

alcohol. Recall that Oxidation Is a Loss of electrons while Reduction Is a Gain of electrons (OIL

RIG). In order to apply this mnemonic, you must know the oxidation states of each atom within

the compound, with particular interest on carbon. Carbon can carry oxidation states ranging

from -4 to +4. A few examples are shown in Figure 1 below. It is also common for carbon to

carry an oxidation state of -3, -1, +1, and +3.

Figure 1. Examples of carbon’s oxidation levels.

You may have noticed that all of the compounds in Figure 1 are neutral and carbon has

zero formal charge in each example. The concept of oxidation state and formal charge are

similar with one important difference in the calculation. Both are calculated by taking the

difference between the valence electrons (from the periodic table) and the number of electrons

belonging to that atom within the molecule. For a given atom, the valence electrons will never

change but the electrons ‘belonging’ the atom in the molecule will vary depending on number of

lone pairs and attachments to more or less electronegative atoms. The important difference in

the calculation of oxidation states and formal charge is based on the following assignment of

bonding electrons (Figure 2). This is how the highlighted carbon in ethanol can have an

oxidation state of -1 but a formal charge of zero.

- Oxidation states assign bonding electrons to the more electronegative atom in a bond,

except when the two atoms are the same and the bonding electrons are split equally.

Answer:

so the reaction would probably would be a chemical reaction

"When benzophenone reduces to diphenylmethanol, leftover products include the CH2OH and NaBH3 species. The energetic CH2OH and NaBH3 quickly bond to give (CH2OH)H3B-Na+. This complex is the main second product of benzophenone reduction."

Reactant Ratios

"In life, four benzophenone molecules react with each BH4 complex. Since four benzophenone molecules each attract a hydrogen atom from the “BH4” hydrogen donor, four “CH2OH”s bond with each boron (B) atom. Realistically, the secondary product is (CH2OH)4B-Na+ and four diphenylmethanol molecules. Focusing on one benzophenone molecule at a time is helpful for explaining and understanding reaction steps."

Explanation:

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

Gamma particles has no mass or charge.

Gamma radiations is a kind of radiations, which are emitted during a nuclear reaction. Gamma radiations are emitted in the form of photons of energy, they did not carry any particles like alpha, beta and proton. So, because of not carrying any particle this radiations have no mass and as it is on the form of energy they also do not carry any charge.

Hence, the particles which has no mass or charge is gamma.

Answer:

76.6% is percent yield of P₄

Explanation:

Percent yield is defined as 100 times the ratio of actual yield and theoretical yield. To solve this quesiton we need to find the theoretical yield of the reaction. Using:

2Ca₃(PO₄)₂(s) + 6SiO₂(s) → 6CaSiO₃(l) + P₄O₁₀(g)

P₄O₁₀(g) + 10C(s) → P₄(g) + 10CO(g)

We need to find the moles of Ca₃(PO₄)₂ and SiO₂ to find limiting reactant. With limiting reactant we can find moles of P₄O₁₀ = Moles of P₄. We must convert the moles of P₄ to mass using Molar mass (P₄ = 123.895g/mol):

Moles Ca₃(PO₄)₂ -Molar mass: 310.1767g/mol-

293.5g * (1mol / 310.1767g) = 0.9462moles

Moles SiO₂ -Molar mass: 60.08g/mol-:

378.5g * (1mol / 60.08g) = 6.30 moles

For a complete reaction of 6.30 moles of SiO₂ there are required:

6.30 moles SiO₂ * (2 moles Ca₃(PO₄)₂ / 6 moles SiO₂) =

2.10 moles Ca₃(PO₄)₂. As there are just 0.9462 moles, Ca₃(PO₄)₂ is limiting reactant

Moles P₄O₁₀ = Moles P₄:

0.9462moles Ca₃(PO₄)₂ * (1mol P₄O₁₀ / 2 mol Ca₃(PO₄)₂) = 0.4731 moles P₄O₁₀ = Moles P₄.

The mass is:

0.4731 moles P₄ * (123.895g / 1mol) = 58.6g = Theoretical yield.

Percent yield is:

44.9g / 58.6g * 100 =

To solve this we must be knowing each and every concept related to speed. Therefore, 5x10⁵s it take light to travel from the Earth to the Sun.

Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.

The average speed is the total distance traveled by the item in a particular time frame. A scalar quantity is average speed. The magnitude of a scalar quantity indicates that it has no direction.

Mathematically,  

speed of light=2.998 x 10⁵m/s.

Time = (1.496x10⁸ km x 1000m/km) / (2.998 x  10⁵ m/s)

Answer:

1. 0.1712M

2. 6.86mg/mL Ca, 12.14mg/mL Cl, 6860000ug/L Ca, 12140000ug/L Cl, 6860mg/L Ca, 12140mg/L Cl, 6860ug/mL Ca, 12140ug/mL Cl.

3. 6860ppm Ca and 12140ppm of Cl.

4. 1.5mL of the 1000ug/mL barium standatd must be taken.

Explanation:

1. Molarity is defined as the amount of moles of solute (Calcium chloride) present in 1L of solution.

The moles of CaCl₂ are:

1.9g CaCl₂ * (1mol / 110.98g) = 0.01712 moles

In 100mL = 0.10L:

0.01712mol / 0.10L = 0.1712M

2. The masses of Calcium and Chloride ions are:

1.9g * (40.078g Ca / 110.98g) = 0.686g Ca

And:

1.9g - 0.686g Ca = 1.214g Cl

mg/mL:

686mg Ca / 100mL = 6.86mg/mL Ca

1214mg Cl / 100mL = 12.14mg/mL Cl

ug/L:

686000ug / 0.1L = 6860000ug/L Ca

1214000ug/ 0.1L = 12140000ug/L Cl

mg/L:

686mg Ca / 0.1L = 6860mg/L Ca

1214mg Cl / 0.1L = 12140mg/L Cl

ug/mL:

686000ug Ca / 100mL = 6860ug/mL Ca

1214000ug Cl / 100mL = 12140ug/mL Cl

3. ppm are defined as mg/L, the ppm of Ca are 6860ppm Ca and 12140ppm of Cl

4. The solution must be diluted from 1000ug/mL to 30ug/mL, that is a dilution of:

1000ug/mL / 30ug/mL:

33.33 times must be diluted the solution.

As final volume of the diluted solution must be 50mL, the volume of the standard needed is:

50mL / 33.33 times = 1.5mL of the 1000ug/mL barium standatd must be taken
