Answer:
— The molality of chloride ions in 300g of water is. A) 1.00 molal. B) 0.500 molal. C) 0.0553 molal. D) 0.111 molal.
1.) produces tremendous amounts of energy with little fuel ( 4 lbs of H-2 and Li-6 produces the same energy as 9,000 T. of Coal )
2.) very abundant fuels Lithium ( for Tritium ) and Deuterium are found everywhere on the Earth Deuterium in water and Lithium in various sources
3.) fusion reactors require very special conditions so the reactions terminate with something goes wrong
1988 was when it was first introduced
Answer:
Crude oil is refined to make petrol (in America this is known as gasoline) or diesel. Most forms of transport use either petrol or diesel to power their engines - from lawnmowers, cars, buses and motorbikes to large ships and aeroplanes.
Answer:
=242.47 g of HF
Explanation:
From the equation One mole of SiO₂ (Silicon (IV) Oxide) react with 4 moles of HF (Hydrogen fluoride).
This is because the reaction ratio is 1:4
The number of moles in182 grams of SiO₂ is:
Number of moles= Mass/RMM
RMM of SiO₂ is 60.08 g/mol
No. of moles=182g/60.08g/mol
=3.0293 moles.
The reaction ratio of SiO₂ to HF is 1:4
Thus the number of moles of HF required to react with 3.0293 moles of SiO₂ is:
(4×3.0293)/1= 12.1172 moles
The mass of 12.1172 moles of HF is.
12.1172 moles× RMM of HF
=12.1172 moles×20.01 g/mol
=242.47 g of HF
