The correct statements which are true for the reactions in the Sun are that are fusion reactions and reactions occur because of very high temperatures.

<h3>What is nuclear fusion?</h3>

Nuclear fusion reactions are those reactions in which two species reacts with each other for the formation of new specie.

In the core of the sun, nuclear fusion of hydrogen atoms occur for the formation of helium molecules in the presence of high temperature.

Hence, the correct statements are they are fusion reactions and reactions occur because of very high temperatures.

If you had 20,000 litres of NO2 how many moles would you have
vova2212 [387]

Answer:

The correct answer is 0.89 mol.

Explanation:

At STP (Standard Temperature and Pressure) conditions, 1 mol of an ideal gas occupies a volume of 22.4 L. If we assume STP conditions, we can consider a convertion factor of 1 mol/22.4 L to convert the volume of NO₂ from liters to moles:

20,00 L x 1 mol/22.4 L = 0.89 mol

So, at STP, we would have 0.89 mol of NO₂

Two waves were analyzed with some high-tech instrumentation. The first wave was found to have a wavelength of 3 x 10 m and the s
a_sh-v [17]

Explanation:

The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m

We need to find which wave have a higher frequency.

The relation between frequency and wavelength is given by :

c=f\lambda

Let f₁ and f₂ be the frequency of wave 1 and wave 2.

f_1=\dfrac{c}{\lambda_1}\\\\f_1=\dfrac{3\times 10^8}{3\times 10^5}\\\\=1000\ Hz

And

f_2=\dfrac{c}{\lambda_2}\\\\f_2=\dfrac{3\times 10^8}{3\times 10^4}\\\\=10000\ Hz

Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.
