Answer: Gamma rays

Explanation:

Gamma rays have the most energies and shortest wavelengths on the electromagnetic spectrum. They are derived from free negatrons and stripped microscopic nuclei stimulated by powerful magnetic fields in exploding stars, colliding neutron stars, and supermassive black holes. Radio waves are the opposite. Radio waves have the lowest energies, longest wavelengths, and lowest frequencies of any EM radiation.

When the released energy reaches the outer layers of the ball of gas and dust, it moves off into space in the form of electromagnetic radiation. The ball, now a star, begins to shine.

Which type of galaxy forms when two other galaxies crash into each other? They are small galaxies made up of bright, young stars

GenaCL600 [577]

Answer:

elliptical galaxy

Explanation

:The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to disappear. The merger of gasses creates new stars, and the new shape becomes more elliptical, globular, or sometimes irregular.

Which of the following has a mass of 10.0 g?

Serjik [45]

Answer:

a. 0.119mol Kr

Explanation:

To solve this problem, we must understand that;

Mass = number of moles x molar mass

Molar mass of Kr = 83.3g/mol

Ar = 40g/mol

He = 4g/mol

Ne = 20.18g/mol

a0.119 mol Kr mass = 0.119 x 83.3 = 9.9g

b 0.400 mol Ar mass = 0.4 x 40 = 16g

C 1.25 mol He mass = 1.25 x 4 = 5g

d 2.02 mol Ne mass = 2.02 x 20.18 = 40.8

Krypton is the answer

Reaction is

-Dominant- [34]

According to the task, you are proveded with patial pressure of CO2 and graphite, and here is complete solution for the task :
At first you have to find n1 =moles of CO2 and n2 which are moles of C
<span>The you go :
</span> $CO2(g) + C(s) \ \textless \ =\ \textgreater \ 2CO(g)$

n1 n2 0
-x -x +2x
$n1-x n2-x 2x Kp=P^2 (CO)/Pco2$
After that you have to use the formula $PV=nRT$
$Kp=(2x)^2/n1-x$
Then you have to solve x, and for that you have to use <span>RT/V
And to find total values:</span> $P(total)=n(total)*R*T/V$
I am absolutely sure that this would be helpful for you.

Given the balanced equation: 2KClO₃ ---> 2KCl + 3O₂ How many moles of O₂ are produced when 4.0 moles of KCl are produced?

Verizon [17]

Answer:

The answer to your question is 6.0 moles of O₂

Explanation:

Data

2KClO₃ ⇒ 2KCl + 3O₂

moles of O₂ = ?

moles of KCl = 4

Process

To find the number of moles of O₂, use proportions and cross multiplication.

Use the coefficients of the balanced equation.

2 moles of KCl ----------------- 3 moles of O₂

4 moles of KCl ----------------- x

x = (4 x 3) / 2

-Simplification

x = 12/2

-Result

x = 6 moles of O₂

-Conclusion

When 4,0 moles of KCl are produced, 6.0 moles of O₂ will be produced.

If density is 22.57g/cm^3 what volume would be occupied by 4.80kg of osmium

steposvetlana [31]

Density is equal to the ratio of mass to the volume.

The mathematical expression is given as:

$density=\frac{mass}{volume}$

Arrange the above expression in terms of volume, i.e.

$volume = \frac{mass}{density}$

Density of osmium is equal to = $22.57 g/cm^{3}$

Mass of osmium = 4.80 kg

First, convert the mass in kg to g:

1 kg = 1000 g

Therefore, mass in g = $4.80\times 1000$ = 4800 g

Put the values,

$volume = \frac{4800 g}{22.57 g/cm^{3}}$

= $212.67 cm^{3}$ .

Hence, volume occupied by osmium = $212.67 cm^{3}$ .
