let the moles of chlorine-35 is n1 and chlorine-37 is n2
now we will use the formula of average atomic mass
![M = \frac{n_1M_1 + n_2M_2}{n_1 + n_2}](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7Bn_1M_1%20%2B%20n_2M_2%7D%7Bn_1%20%2B%20n_2%7D)
here let say
![\frac{n_1}{n_2} = x](https://tex.z-dn.net/?f=%5Cfrac%7Bn_1%7D%7Bn_2%7D%20%3D%20x)
![35.45 = \frac{x(35) + 37}{x + 1}](https://tex.z-dn.net/?f=35.45%20%3D%20%5Cfrac%7Bx%2835%29%20%2B%2037%7D%7Bx%20%2B%201%7D)
![35.45 x + 35.45 = 35x + 37](https://tex.z-dn.net/?f=35.45%20x%20%2B%2035.45%20%3D%2035x%20%2B%2037)
![35.45 x - 35 x = 37 - 35.45](https://tex.z-dn.net/?f=35.45%20x%20-%2035%20x%20%3D%2037%20-%2035.45)
![0.45 x = 1.55](https://tex.z-dn.net/?f=0.45%20x%20%3D%201.55)
![x = 3.44](https://tex.z-dn.net/?f=x%20%3D%203.44)
so here since ratio of moles of chlorine 35 and chlorine 37 is more than 1 so chlorine 35 is more in the proportion in this mixture so <em>there is most chlorine atom consist of 18 neutrons</em>
Answer: C
Explanation:
A collision in which the objects stick together is sometimes called “perfectly inelastic“
Because they’re far from each other and the J0523 has lower mass then the UY which is a red dwarf.
Answer:
All the predictions in the impact theory are true.
Explanation:
That’s because of their predictions. Modern computer simulations predict that there happened a collision between Earth and a planet named as Theia. The chunks of both planets conformed into a stable orbit and form the satellite that we know today as our Moon. Similarly, both moon and Earth share similar mantle compositions but cores are dissimilar in terms of their size and composition.
Answer:
<em>Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, Earth science, and astronomy.</em>
