Solution :
The sun emits =
J of energy per second
= ![$4 \times 10^{26} \ kg m^2 s^{-3} $](https://tex.z-dn.net/?f=%244%20%5Ctimes%2010%5E%7B26%7D%20%5C%20kg%20m%5E2%20s%5E%7B-3%7D%20%24)
We know, ![$1 \ J =1 \ kg \ m^2 / s^2 $](https://tex.z-dn.net/?f=%241%20%5C%20J%20%3D1%20%5C%20kg%20%5C%20m%5E2%20%2F%20s%5E2%20%24)
, where C = ![$3 \times 10^8 \ m/s$](https://tex.z-dn.net/?f=%243%20%5Ctimes%2010%5E8%20%5C%20m%2Fs%24)
![$E=mC^2$](https://tex.z-dn.net/?f=%24E%3DmC%5E2%24)
![$J=M(M/s)^2$](https://tex.z-dn.net/?f=%24J%3DM%28M%2Fs%29%5E2%24)
Dividing both sides by 1 second
![$\frac{J}{s}=M \times m^2 s^{-3}$](https://tex.z-dn.net/?f=%24%5Cfrac%7BJ%7D%7Bs%7D%3DM%20%5Ctimes%20m%5E2%20s%5E%7B-3%7D%24)
Then, ![$4 \times 10^{26} \ J/s = M \times m^2 s^{-3} \times (3 \times 10^8)^2$](https://tex.z-dn.net/?f=%244%20%5Ctimes%2010%5E%7B26%7D%20%5C%20J%2Fs%20%3D%20M%20%5Ctimes%20m%5E2%20s%5E%7B-3%7D%20%5Ctimes%20%283%20%5Ctimes%2010%5E8%29%5E2%24)
![$M = \frac{4 \times 10^{26}}{9 \times10^{16}}$](https://tex.z-dn.net/?f=%24M%20%3D%20%5Cfrac%7B4%20%5Ctimes%2010%5E%7B26%7D%7D%7B9%20%5Ctimes10%5E%7B16%7D%7D%24)
![$M=4.44 \times 10^9 \ kg$](https://tex.z-dn.net/?f=%24M%3D4.44%20%5Ctimes%2010%5E9%20%5C%20kg%24)
Now according to the information, 99.3% hydrogen.
If 0.7 % of hydrogen produce =
J of energy per second
Then 1% of hydrogen will produce =
J energy per second
So, 100% of hydrogen will produce =
J energy per second
=
J energy per second
Mass of hydrogen undergo fusion in sun per second
![$E=mC^2$](https://tex.z-dn.net/?f=%24E%3DmC%5E2%24)
Similarly, ![$\frac{J}{s}=M \times m^2 s^{-3}$](https://tex.z-dn.net/?f=%24%5Cfrac%7BJ%7D%7Bs%7D%3DM%20%5Ctimes%20m%5E2%20s%5E%7B-3%7D%24)
![$5.714 \times 10^{28} \ J/s = M \times (3 \times 10^8)^2 \ m^2 \ s^{-3}$](https://tex.z-dn.net/?f=%245.714%20%5Ctimes%2010%5E%7B28%7D%20%5C%20J%2Fs%20%3D%20M%20%5Ctimes%20%283%20%5Ctimes%2010%5E8%29%5E2%20%5C%20m%5E2%20%5C%20s%5E%7B-3%7D%24)

A process called respiration. This process is carried out in organelles in the cell<span> called the Mitochondria.</span>
The best answer I would think would be A
Electrons carry a negative charge, so when you add on to the electron, the ion gets more negative.
hope this helps!
0.05 mol of oxygen atom.
Explanation:
Mass of potassium hydroxide = 2.79g
Unknown:
Number of moles = ?
Solution:
To solve this problem, find the number of moles of the potassium hydroxide.
Number of moles of KOH = ![\frac{mass}{molar mass}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D)
Molar mass of KOH = 39 + 16 + 1 = 56g/mol
Number of moles of KOH =
= 0.05mole
Now,
1 mole of KOH contains 1 mole of oxygen atom
0.05 mole of KOH will have 0.05 mole of oxygen atom.
