Answer:
What is this about?
Explanation:
Its probably a transmitter wave
Answer: 6.02 x 10^25
Explanation:
In order to find the number of molecules you simply multiply the number of moles by 6.022 x 10^23.
1 mole is always equal to 6.022 x 10^23 no matter what element.
100.0 x 6.022 x 10^23 = 6.02 x 10^25
The answer only has three significant figures because 100.0 only has three.

Answer:
2.7×10⁻³ mole
Explanation:
Applying
Q = it.............. Equation 1
Where Q = amount of charge, i = current, t = time
From the question,
Given: i = 0.860 A, t = 5 minutes = (5×60) seconds = 300 seconds
Subsitute these values into equation 1
Q = (0.860×300)
Q = 258 C
If one mole of electron has a charge of 96500 C
Then, x mole of electron will have a charge of 258 C
1 mole ⇒ 96500 C
X moles ⇒ 258 C
Solve for X
X = (258×1)/96500
X = 2.7×10⁻³ mole
Whenever the fuel is being used up, a star explodes and the energy leakage from a star's core ceases.
Explanation:
The dying star expands in the "Red Giant," before even the inevitable collapse starts, due to nuclear reactions just outside of the core.
It becomes a white dwarf star when the star has almost the same density as the Sun. If it's much larger, a supernova explosion could take place and leave a neutron star away. However, if it is very large–at least three times the Sun's mass–the crumbling core of the star, nothing will ever stop it from crumbling. The star is imploding into a black hole, an endless gravitational loop in space.
