The SI base units for length is meter (m) and for time is seconds (s).
The given ratio is 
Converting mm/s to m/s as:
Since, 1 mm/s = 0.001 m/s
So, 
Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of to three significant figures and answer in SI units is 
.
1 mole -------- 22,4 L ( at STP )
0.030 moles --- ?
V = 0.030 * 22,4 / 1
V = 0.672 L
hope this helps!
Answer:
Uranium-233- fission
Plutonium-239- fission
Plutonium-241- fission
Hydrogen-3 fusion
Hydrogen-1 fusion
Helium-3 fusion
Explanation:
In nuclear fission, heavy nuclear disintegrate into smaller nuclei when bombarded with particles such as neutrons. Fission reaction is common among nuclei having a high atomic number such as plutonium and uranium.
Fusion occurs between two light nuclei such as hydrogen or helium. It involves the combination of two lighter elements to give a heavier element with the release of tremendous amount of energy.
Answer:
Once I read a NASA post where they were saying that the universe keeps expanding as matter keeps forming and cooling down thus adding to the size of the universe so keeping this in mind, the best answer choice is, <u>option A. The universe is currently expanding and will continue to expand.</u>
1 ) Cobalt(II) nitrate react with nitrate zinc(II) to produce cobalt(III)-zinc oxide, nitrogen dioxide and oxygen
2Co(NO3)2 + Zn(NO3)2 → Co2ZnO4 + 6NO2 + O2
2) Calcium hydroxide react with phosphoric acid to produce calcium, hydrogen phosphate and water
Ca(OH)2 + H3PO4 → CaHPO4 + 2H2O
3) Copper(II) dichromate will react with Iron(III) arsenate to form Copper(II) Arsenate and Iron(III) dichromate
3Cr2CuO7 + 2AsFeO4 → Cu3(AsO4)2 + Fe2(Cr2O7)3
Reaction Type
: Double Displacement
4) aluminium hydroxide and hydrochloric acid react to form aluminium chloride and water
Al(OH)3 + 3HCl → AlCl3 + 3H2O
