What are formed when particles in solar wind travel along lines of Earth's magnetic field and collide with gas atoms?

What is the frequency,in Hz,of electromagnetic radiation that has a wavelength of 1.25m

Kryger [21]

Answer:

$f=2x10^8Hz$

Explanation:

Hello!

In this case, given that frequency of the electromagnetic radiation showing off a wavelength of 1.25 m is computed by using the speed of light as shown below:

$f=\frac{c}{\lambda }$

We plug in the wavelength and speed of light to obtain:

$f=\frac{3x10^8m/s}{1.25m } \\\\f=2x10^8Hz$

Best regards!

calculate the concentration in parts per million (ppm) of DDT if a sample size of 2000 g contained 0.050 g DDT

Firlakuza [10]

Answer:

= 25 ppm

Explanation:

PPM also refers to parts per million, it represents a low concentration of a solution. It represents 0.001 gram or a milligram in a 1000 mL, which equivalent to 1 mg per liter.

Given; a sample size of 2000 g contained 0.050 g DDT

It means, 2000 mL sample contained 50 mg DDT

Therefore in ppm we get;

= 50 mg/ 2 L

= 25 mg/L

<u>= 25 ppm</u>

Predict the chemical formula of butyne, having one carbon-carbon triple bond.

Svet_ta [14]

Butyne is the alkyne with four carbon atoms, and, as the question states, it has one carbon-carbon triple bond. The general formula of an alkyne is CnH2n-2, that means that when there are 2 carbons the formula is C2H2, when there are 3 carbons the formula is C3H4, and when there are 4 carbons the formula is C4H6. So, <span>butyne is C4H6 or " CH3-C (triple bond) C - CH3" (note that I wrote the phrase triple bond between the two Cs in the middle of the formula because there is no way to draw the three hyphens stacked one over other").</span>

The multistep smelting of ferric oxide to form elemental iron occurs at high temperatures in a blast furnace. In the first step,

mr_godi [17]

Balanced equation of iron melting process

$3Fe_{2} O_{3}$ + $CO$ → $2FeO4+C_{2}$

$2Fe_{3} O_{4} + 2CO$ → $6FeO+2CO_{2}$

$6FeO +6CO$ → $6Fe+6CO_{2}$

After balancing, we get

$Fe_{2} O_{3}_{(g)} + 3CO_{(g)}$ → $3CO_{2} _{(g)} +2Fe_{(s)}$

<h3>Briefly described</h3>

Given descriptions of steps of a complex chemical reaction, we can find the overall chemical reaction by adding together the individual equation. The first step is to take our words and write them in equations, So the first reaction has a compound called ferric oxide. Feyerick is the eye on with a plus three charge, and oxide is a to minus.

So ferric oxide, the neutral compound is Effie to 03 This reacts with carbon monoxide, which is CO2 make a new compound F E 304 plus carbon dioxide, which is CO2 ,In the second step, take a product that I formed in the first and reacted with more carbon monoxide to make iron two oxide iron to means it has a charge of two plus, and again, oxide is o to minus.

So the formula is FV oh, plus carbon dioxide. Finally, the F B o reacts with carbon monoxide to form molten iron, which is just solid metal iron plus sio two. Once we have the skeleton equations, we can balance them for the first equation. I have two irons here and three irons here, so I need a three here and two here for my coefficient. This gives me six irons and six irons. I have a total of 10 oxygen's on the side and 10 oxygen's on this side and one carbon.

So the equations balanced for the second equation. Normally, I would balance it looking for the lowest whole number ratio, but in this case, I have to of these produced. So I have to balance the equation, taking that into account so it won't necessarily be the lowest whole number ratio. And in fact, the ratio is two of these with six irons here, for a total of 10 oxygen's on this side in 10 oxygen's on this side and two carbons and to carpet.
