What do substances that conduct electricity once they are dissolved have in common?
Answer:
They are ionic compounds.
Explanation:
Ionic compounds are made from a metal element and a nonmetal element. Ionic compounds have bonds that are the transfer of their electrons. They consist of a positively charged and negative charged ion.
When ionic compounds are dissolved in water, this means that the bonds from the compound are broken and now they will be bonding with the water molecules in water.
The electricity in the solution happens when these ions are moving around freely in water.
The air pressure in a tank is measured using an inclined manometer whose arm is inclined 45 degree from the horizontal line. The densities of the air and water are 1. 225 kg/m3 and 1000 kg/m3, respectively. Determine the gauge pressure of air in the tank.
The gauge pressure of air in the tank is Pg= 1.076 psi
Gauge pressure (sometimes written as "gauge pressure") is measured relative to the local atmospheric pressure. Gauge pressure is thus zero when the pressure is the same as atmospheric pressure. Gauge pressure is indicated by pg, and is related to absolute pressure as follows: pg = p - pa, where pa is the local atmospheric pressure.
Given these data
Density of air = 1.225 kg/m3
Density of water = 1000 kg/m3
Note that the absolute pressure of air in the tank = 100kpa
Acceleration due to gravity = 9.8 m/s2
P=hρg
100 = h * 1000* 9.8
h = 98m
So replacing the value of h to calculate the atmospheric pressure
P=hρg
P= 98 *1.225*9.8
P= 1176.49
Substitute these values into the formula
Pg= p - pa,
Pg= 1176.49-100
Pg= 1.076 psi

1-bromo-2-methylpropane undergoes an Sn2 reaction with the methoxide to yield 1-methoxy-2-methylpropane (isobutyl methyl ether) and the bromide ion. Please see the reaction mechanism shown in the attached material.
Alkyl halides are excellent electrophiles because of the polar carbon-halogen bond that provides both the electrophilic carbon atom and the excellent leaving group in the form of the halide ion. When attacked by a nucleophile (such as the methoxide ion), they undergo an Sn2 reaction (bimolecular nucleophilic substitution).
The reaction mechanism of an Sn2 reaction consists of a single phase: the simultaneous attack by the nucleophile and the abstraction of the leaving group. This process implies that there is a transition state that contains a quasi-pentavalent carbon atom, as one bond is forming and the other is being dissolved.

According to the Gaussian distribution model, 8.8 x [tex]10^{11}[/tex][tex]cm^{-2}[/tex] energy is required to design the implant setup.
A probabilistic model called a "Gaussian mixture model" posits that all of the data points were produced by combining a limited number of Gaussian distributions with unknown parameters.
First, the mean and covariance functions of a Gaussian distribution model are the only variables that matter. Due to the fact that just the first and second order moments of the process need to be specified, this attribute makes model fitting easier. Second, it's not too difficult to solve the prediction problem using Gaussian distribution model.
Given:
At z = 50nm
C (50nm) = 1 x [tex]10^{16} cm^{-3}[/tex]
C (50nm) / Cp = 0.1
Calculations:
Using the Gaussian distribution model, the concentration as a function of depth can be related to peak concentration, Cp:
[tex]Cz = Cp * exp ( - \frac{(z - Rp)^2}{2\Delta R^2p} )[/tex]
Taking log on both sides,
[tex]\sqrt{2ln10}[/tex] = Rp – 0.05 / ΔRp = 2.416
To find an energy that gives Rp – 2.15 ΔRp = 0.05µm
(By trial and error method)
100 Kev Rp = 0.125, ΔRp = 0.035, Rp – 2.15 ΔRp = 0.048µm
120 Kev Rp = 0.15, ΔRp = 0.040, Rp – 2.15 ΔRp = 0.064µm
Interpolating linearly between 100 and 120 Kev gives about 103Kev.
At this energy, ΔRp = 0.035 µm
Therefore,
[tex]Q = \sqrt{2\pi } \Delta Rp Cp[/tex] = 8.8 x [tex]10^{11}[/tex][tex]cm^{-2}[/tex]

acid flux is designed to be used on nonelectrical metal joints such as radiators and must be removed after the soldering process so that the joint does not corrode.
It is true that acid flux is used on non-electrical metal joints, such as radiators but need to be removed so that the joint does not corrode after soldering.
Acid flux must be removed after soldering in order to prevent corrosion of the junction and is intended to be used on non-electrical metal connections, such as radiators.
A substance called acid soldering flux is applied to the joint between two pieces of metal to clean and shield it.
Fluxing achieves three objectives: it lessens oxidation, enhances electrical contact, and promotes uniform solder flow. Flux helps eliminate oxidation from the electrical lead you are soldering and blocks airflow to the lead, preventing additional oxidation.
Water-soluble flux is another name for organic acid flux. These organic acids, including citric, lactic, and stearic acid, are used to make this sort of flux. After that, organic solvents like alcohol or isopropyl are added to the acids. Metal oxides can be removed more successfully using organic acid flux.
As a result, it is accurate to say that acid flux must be removed after soldering in order to prevent corrosion of the joint on non-electrical metal components like radiators.

One mole of iron _____.
has the same mass as one mole of lead.
cannot be compared to lead because it is magnetic.
has less mass than one mole of lead.
has more mass than one mole of lead.
Answer:
One mole of O2 will have approximately the same mass as one mole of methanol (CH3OH).
Recall that: mole = mass/molar mass
Thus, one mole O2 will have a mass of:
mass = mole x molar mass
= 1 x 32
= 32 g
One mole of CH3OH = mass/molar mass
mass = 1 x 32
= 32 g
Hence, 1 mole of O2 will have the same mass (32 g) as 1 mole of CH3OH
As a reminder, the atomic mass of an atom equals the mass of a mole of this atom.
Just so you know, a mole is defined as a quantity of 6.02x10^{23} things.
We know that the atomic mass of Oxygen is 16 so one mole of O2's mass is 16*2=32g.
So I guess we need to figure out something which a mole of will weight 32 g.
You can pick Ethanol which formula is CH3OH.
C has an atomic mass of 12
H has an atomic mass of 1
O has an atomic mass of 16
So one mole of CH3OH weights 12+(3*1)+16+1=32g which is the same amount.

describe dehydration synthesis. in your answer, use starch synthesis as an example. be sure your answer includes the roles of starch, glucose, polymers, monomers, water, and covalent bonds in the process.
The chemical process known as dehydration synthesis, also known as a condensation reaction, involves the covalent bonding of two molecules to create a new molecule while simultaneously releasing a water molecule.
Complex carbohydrates, proteins, DNA, and RNA are just a few of the molecules that are formed via dehydration synthesis processes and are crucial to human health.
Dehydration synthesis forms covalent bonds between sugar molecules. The hydroxyl (-OH) group from one reactant joins with the hydrogen atom from the other to generate water throughout the reaction, while the leftover oxygen forms a glycosidic bond that binds the two molecules together. Repeated dehydration synthesis of individual glucose molecules (monomers) can result in the formation of a polymer, which is a long chain or branched chain structure.
Dehydration synthesis processes, in which one monomer establishes a covalent connection to another monomer (or expanding chain of monomers), release a water molecule in the process, are frequently used to create large biological molecules. Dehydration stands for the loss of the water molecule and synthesis for the development of a new bond, making it easy to recall what occurs.
The methods through which monomers can combine to produce polymers are quite diverse. For instance, starch, cellulose, and glycogen are all made up of glucose monomers. These three polysaccharides, which are categorized as carbohydrates, were created as a result of several glucose monomer-to-glucose dehydration synthesis processes. These three distinct polysaccharides, however, have varied characteristics and functions because of the way that glucose monomers combine, particularly the positions of the covalent connections between linked monomers and the orientation (stereochemistry) of the covalent bonds.

Explanation:
An element can be found on the periodic table, and are only composed of one type of atom. For example, carbon is an element because you can find it on the periodic table. Fire isn't an element because you can't find it on the periodic table. A short-cut to see if something is an element is to look at the number of capital letters in the formula. If it only has one capital letter, it is an element. If it has two or more, it is a compound. This works because elements always have only one capitalized letter. For example, Ne has a capitalized N. O has a capitalized O. This only works if you are given the molecular formula and not the name, so looking at the periodic table is the best thing to do.
