cyanoacrylate
When cyanoacrylate polymerizes, the cyanoacrylate sticks together on an atomic level, and it becomes solid. Super Glue solidifies in all the microscopic crevices of an object that it moved into when it was a liquid, and it can form chemical bonds with any anions in the object.
Ga₂O₃ + 2NaOH + 3H₂O = 2Na[Ga(OH)₄]
[Ga(OH)]⁻ + 3e⁻ = Ga + 4OH⁻
n(Ga)=It/(zF)
I=0.200 A
t=40.0 min=2400 s
z=3
F=96485.33 Kl/mol
n(Ga)=0.200*2400/(3*96485.33)=0.00166 =1.66*10⁻³ mol
Answer:
(D) Trench
Explanation:
The term 'trench' is used for the deepest parts of the ocean floor. Ridge is 2 km above the deepest part of ocean floor. Hydrothermal vent are generally found near the active volcanic places. Hydrothermal vent are fissures on sea-floor.
<span>Step 1: Convert the given amount to moles, by dividing the given amount by the molecular weight of the compound.
5 g C3H8 (1 mol / 44 g C3H8) = 0.114 mol C3H8
Step 2: Find the mole ratio between the given and the desired target (in this case water). The mole ratio between C3H8 and water is 1:4, that is, you can make 4 times as much water from a one C3H8 (assuming that it isn't the limiting reactant).
0.114 mol C3H8 (4 moles H2O / 1 mol C3H8) = 0.456 mol H2O
Step 3: Reconvert back to grams by multiplying by the molecular weight of the new target (water).
0.456 mol H2O (18 g / 1 mol H2O) = 8.208 g Water. Hope this helped! :) </span><span />
I believe it would be transfering heat into a cold class or vise versa
Hope this helpesss (':
