The answer is D. His belief is was that atoms could not be split. That is what was disproved really fast ;)
Answer: The issue of long-term effects of the Chernobyl disaster on civilians is very controversial. The number of people whose lives were affected by the disaster is sizable. Over 300,000 people were resettled because of the disaster; millions lived and continue to live in the contaminated area.
Explanation:
Answer:
C.) A generator transforms mechanical energy into electrical energy with the help of static electricuty
Example:
they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.
(Hope this helps) sorry if it's wrong
I believe it is spontaneous generation
Answer:
![\frac{4molPF_3}{1molP_4}](https://tex.z-dn.net/?f=%5Cfrac%7B4molPF_3%7D%7B1molP_4%7D)
Explanation:
Hello
In this case, given the reaction:
![P_4(s)+6F_2(g)\rightarrow 4PF_3(g)](https://tex.z-dn.net/?f=P_4%28s%29%2B6F_2%28g%29%5Crightarrow%204PF_3%28g%29)
It means that since the coefficients preceding phosphorous and phosphorous trifluoride are 1 and 4, the correct mole ratio should be:
![\frac{4molPF_3}{1molP_4}](https://tex.z-dn.net/?f=%5Cfrac%7B4molPF_3%7D%7B1molP_4%7D)
Because given the mass of phosphorous it is convenient to convert it to moles and then cancel it out with the moles on bottom of the mole ratio.
Bes regards!
