All but one of the halides will produce a precipitate with Silver.
What are Halides?In chemistry, a halide (rarely halogenide) is a binary chemical compound made of two elements or radicals, one of which is an atom of a halogen and the other of which is an element or radical that is less electronegative (or more electropositive) than the halogen. These elements or radicals can be combined to form a fluoride, chloride, bromide, iodide, astatide, or theoretically a Tennessee compound. Under the right circumstances, the alkali metals immediately react with halogens to generate halides with the general formula MX (X = F, Cl, Br, or I). The hal- syllable in halide and halite reflects the fact that many salts are halides. At room temperature, all Group 1 metals produce halides, which are white solids.To learn more about Halides, refer to:

Earthquakes generate shock waves that travel through earth's interior to other parts of the world. The fastest of these waves are longitudinal waves, like sound waves and are called primary or, just p waves. A pwave has a very low frequency typically around 0.050Hz. If the speed of a pwave with this frequency is 8.0km/s what is its wavelength
Answer:
16 HzExplanation:
wavelength = v/ f where v=speed (0.8km/s)
f=frequency (0.050Hz)
= 8.0/ 0.050

What speed will you have to go from Chicago to Hackensack in 260 hours
Speed you will have to go from Chicago to Hackensack in 260 hours is 4.9Km/hr.
The pace at which an object's position changes in any direction is referred to as its speed. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.Speed = distance / timeUnit of speed is Km/hr or m/sec. Speed is calculated by dividing the distance travelled by the amount of time it took to get there. Divide the distance by the speed to find the passing time. Multiply the speed by the time to find the distance.Given,
Time = 260 hours
distance between Chicago to Hackensack is 1277 km
So speed = 1277/ 260 = 4.9 Km/ hr
Therefore, speed required to go from Chicago to Hackensack in 260 hours is 4.9 Km/ hr.

How many monochlorination products can be formed (constitutional isomers only) from the reaction of ch3ch2ch2ch2ch2ch3 with cl2 in the presence of light?
3 monochlorination products can be formed (constitutional isomers only) from the reaction of CH3CH2CH2CH2CH2CH3 with Cl2 and hν.
What is the end result of monochlorination?Isomeric products are formed when alkanes larger than ethane are halogenated. Thus, when propane is chlorinated, both 1-chloropropane and 2-chloropropane are produced as mono-chlorinated products.All isomeric alkanes with the formula C5H10 can yield a total of fourteen monochlorinated products (excluding stereoisomers).2,2-dimethylpropane. Chlorination is one of the reactions that alkanes undergo, in which a hydrogen atom in the alkane is substituted with a chlorine atom when the alkane is reacted with chlorine in the presence of light. We discussed a relatively simple reaction last time: free-radical chlorination of methane to (CH4) to give chloromethane (CH3Cl), and how the reaction proceeds through three stages: initiation (where free radicals are formed), propagation (the main "product-forming" step of the chain reaction, where a chloroalkane is formed without net formation of new free radicals), and termination (where radicals combine, resulting in a net reduction of the number of free radicals).To learn more about monochlorination refer to

Two objects labeled A and B are the same size object A has a density of 1.21g/cm square root 3 object B has a density of 1.37g/cm square root 3 if both are placed in a beaker of water which will float higher in the water
The object that will float higher in the water is the object whose density is 1.21g/cm^3.
What is density?The term density is the ratio of the mass to the volume of an object. We know that density is an intrinsic property hence it does not depend on the amount of substance that is present therefore, we could use the density of a substance to identify the substance.
The greater the density of an object, the more the object sinks into the water much farther. We now need to compare the two objects. The object that has the higher density would tend to sink deeper into water.

Calculate the ph of a blood plasma sample with a total co2 concentration of 25.6 mm and bicarbonate concentration of 24.4 mm. the relevant pa of carbonic acid is 6.1.
The pH of the blood plasma sample is 6.1.
The solution of carbonic acid and bicarbonate is a buffer solution. In buffer solution is a mixture of a weak base or acid and its conjugate salt. Resisting change in pH is one of the properties of a buffer system.
The concentration of carbon dioxide = 25.6 mM
The concentration of bicarbonate concentration =
24.4 mM
Pa of the carbonic acid = 6.1
The pH of the blood plasma sample with a total carbon dioxide of 25.6 mM and a bicarbonate concentration of 24.4 mM.
[tex]pH = pK _{a} + log \frac{[ HCO]}{[ H _{2}CO _{3} ]}[/tex]
[tex]pH = 6.1 + log \frac{[24.4]}{[25.6 ]}[/tex]
pH = 6.1 + log (0.953)
pH = 6.1 - 0.209
pH = 6.1
The pH of the blood plasma sample with a total carbon dioxide of 25.6 mM and bicarbonate concentration of 24.4 mM is 6.1.

V(glycine) = 10 ml = 0.01 l; volume of glycine
c(glycine) = 1.0 M, concentration of glycine
n(glycine) = 0.01 mol; amount of glycine
pKa(glycine) = 9.6
Henderson–Hasselbalch equation for the buffer solution:
pH = pKa + log(ns/nk)
9 = 9.6 + log(ns/nk)
log(ns/nk) = -0.6
ns/0.01 mol = 0.251
n(KOH) = 0.00251 mol; amount of potassium hydroxide at pH = 9
V(KOH) = 0.00251 mol ÷ 0.05 mol/l
V(KOH) = 0.0502 l; volume of potassium hydroxide at pH = 9
10 = 9.6 + log(ns/nk)
log(ns/nk) = 0.4
ns/0.01 mol = 2.51
n(KOH) = 0.0251 mol; amount of potassium hydroxide at pH = 10
V(KOH) = 0.0251 mol ÷ 0.05 mol/l
V(KOH) = 0.502 l; volume of potassium hydroxide at pH = 10

103mL of 1.36M HCl are required for this dilution, followed by the addition of 197mL (500mL-200mL-103mL) of water to finish the dilution.
What is a solution?
A similar mixture of components is referred to as a solution. On a particle-by-particle basis, it is homogeneous. Most of the time, people picture it as a liquid that has a solid, liquid, or gas dissolved in it. This is not totally accurate, though. Alloys are a good alternative that we may use.
First, the goal is to make 200mL of 2.4M HCl and 500mL of 1.24M HCl from 1.36MHCl. In other words, the total amount of HCl in the final solution depends on how many moles each of the two solutions has.

Let n1=n (500mL,1.24M HCl)

What is activation energy?The least amount of energy needed for a reaction to take place is called the activation energy. This indicates that the reactant molecules have sufficient kinetic energy to successfully collide and get rid of the outer electron repulsion.
A spark is required to ignite a fuel's burning reaction. A fuel must be burned with at least a certain amount of energy. The activation energy is the bare minimum of energy required for a reaction to occur.

In this model of a reaction, how do you interpret the orange balls being positioned in the middle of a line drawn between two atoms?
The orange balls being positioned in the middle of a line drawn between two atoms interpret a nonpolar bond exists between the two atoms.
In nonpolar bonds the arrangement of electrons are in the middle between two atoms (see the picture below).
The orange balls represent the electrons.
For example, nitrogen molecule (N₂) has strong nonpolar triple covalent bond (:N:::N:), that is why it is very stable and have low reactivity.
In molecule of nitrogen (N₂), bond order is 3 , because there are three pair of electrons (6 electrons) between nitrogen atoms.

Standard sets of settings for experimental measurements are produced at standard temperatures and pressures (STP), allowing comparisons to be made between various sets of data. The most popular standards, though not universally acknowledged, are those of the National Institute of Standards and Technology (NIST) and the International Union of Pure and Applied Chemistry (IUPAC).

Compound naming requires adherence to a set of rules. For identifying organic compounds, the nomenclature (name system) of the IUPAC (International Union of Pure and Applied Chemistry) is used. The names will be uniform as a result.
Prefixes are used in the IUPAC nomenclature before the root. Because they show if an organic molecule has side chains or substituent groups, prefixes are highly useful. These prefixes also indicate the cyclic or acyclic nature of the substances at issue.
