Which is the best metal to use in an alloy to increase its electrical conductivity

Answers

Answer 1
Answer: Copper would be the best
Answer 2
Answer: Silver, Copper, Gold, Aluminum, and brass are the top best conductors in that order. Silver being best and brass still being good but not better than the others. I would try you luck with silver and copper the most.

Five liters of gas at STP have a mass of 12.5 g. What is the molecular mass of the gas? a. 12.5 g/mol
b. 25.0 g/mol
c. 47.5 g/mol
d. 56.0 g/mol
e. 125 g/mol

Answers

You have 12.5 grams. And 5 liters of some random gas. 

Step 1: You must find the mol amount of that 12.5g mass. 

12.5 / 5 = 2.5 mol 

Step 2: Now find the molecular mass of that gas "at STP" (STP- is 22.4 L) 

2.5 x 22.4 = 56 g/mol

An igneous rock originally has 3 grams of uranium 238 in it. When dated the rock only contains 1.8 grams. What are the parent and daughter concentrations (in percentages) and what is its age?

Answers

Answer :

The parent and daughter concentrations (in percentages) is, 60 % and 40 % respectively.

The age of rock is 3.32* 10^9\text{ years}

Explanation :

First we have to calculate the parent and daughter concentrations (in percentages).

\text{Parent concentrations}=(1.8g)/(3g)* 100=60\%

and,

\text{Daughter concentrations}=((3-1.8)g)/(3g)* 100=40\%

As we know that, the half-life of uranium-238 = 4.5* 10^9 years

Now we have to calculate the rate constant, we use the formula :

k=(0.693)/(t_(1/2))

k=\frac{0.693}{4.5* 10^9\text{ years}}

k=1.54* 10^(-10)\text{ years}^(-1)

Now we have to calculate the time passed.

Expression for rate law for first order kinetics is given by:

t=(2.303)/(k)\log(a)/(a-x)

where,

k = rate constant  = 1.54* 10^(-10)\text{ years}^(-1)

t = time passed by the sample  = ?

a = initial amount of the reactant  = 3 g

a - x = amount left after decay process = 1.8 g

Now put all the given values in above equation, we get

t=(2.303)/(1.54* 10^(-10))\log(3)/(1.8)

t=3.32* 10^9\text{ years}

Therefore, the age of rock is 3.32* 10^9\text{ years}

Which can associate a suspect and the firing of a gun?( its not b )
A) markings on the gun's exterior
B) markings on the casing
C) markings on the bullet
D) powder residues

Answers

One that is can associate a suspect and the firing of a gun is powder residues. The correct option is D.

What is gun power residue?

GSR is made up of unburned or partially burned gunpowder particles, soot, nitrates, and nitrites from powder combustion, primer particles (oxides of lead, antimony, and barium), and bullet or bullet jacket particles that are vaporized when a firearm is discharged.

Gunshotresidue (GSR) is a speck of vital trace evidence that assists forensic scientists in solving a wide range of firearm-related incidents.

The identification of the shooter, as well as bullet identification from a gunshot wound, aid in the reconstruction of a crime scene.

Powderresidues are one thing that can link a suspect to a gunshot.

Thus, the correct option is D.

A chemistry student must separate should barium sulfate from the aqueous solution. Equipment and glassware normally found in the chemistry classroom are available to the student.Describe how the student could separate the solid barium from the aqueous solution. Be sure to list the lab equipment needed to do the procedure
Explain how each item is used in the procedure

Answers

If there's just some barium put in an aqueous solution, then it should be something like this.
It's a mixture of a solution and an insoluble solid, so the easiest way to go is through filtration. (Also, I'm assuming the barium is cut into very small chips.)

In a line, simply filter the solution using a folded filter paper in a funnel, collect the residue in a beaker or flask, rinse it with distilled water and let it dry. (Or simply filtering it could be enough, depending on how far your teacher wants you to go.)

Stuff needed:
>filter paper (for separating the solid from the solution)
>funnel (to hold the filter paper)
>beaker or flask (to hold the filtrate)
>distilled water (to rinse the solid)
>spatula (to scoop up the solid)

Procedure:
>Fold filter paper and line the funnel with it. Place the funnel in the flask or beaker.
>Pour solution in. Then add water (I think using tap water might be fine in this case, but you can use distilled water if you'd like) to wash out the container with the solution of any solid you may have not gotten in the first try. Alternatively, you could use a spatula to spoon it onto the filter paper.
>Once everything has been filtered, pour some distilled water on the residue on the filter paper to wash away the solution.
>Take out the filter paper, open it up and let it dry.

This can be used in real life in many occasions. For example, when you make tea, you need to filter the leaves out. Or when you cook the pasta, you put it in a sieve to separate the pasta from the water. Or when you fish using fishing nets, you "filter" the fish from the water.
