Distinguish between the terms "insoluble" and "unsaturated." Give an example to illustrate each term.
Serjik [45]
Insoluble means that a substance does not dissociate in another, like mixing water and oil.

In an unsaturated solution, the solute does dissociate into solution but there is more "room" in the solution to hold more. Say if you have an amount of water that can dissolve 20g of salt but you only have 15g dissolved in it, that solution is unsaturated.

2 C6H14 + 19 O2 --> 12 CO2 + 14 H2O
vivado [14]

Answer:

1.27 moles (3 s.f.)

Explanation:

Mole ratio of water: C6H14

= 14:2

= 7:1

This means that to produce 7 moles of water, 1 mole of C6H14 is needed. Or 1/7 mole of C6H14 is needed to produce 1 mole of water. So if you need 8.86 moles of water, 8.86(1/7) moles of C6H14 is needed.

For 8.86mol of water, moles of C6H14 needed

= 8.86/7

= 1.27 moles (3 s.f.)

Charra [1.4K]

very cold temperatures

Explanation:

A superconductor performs best at very cold temperatures.

A superconductor is a perfect conductor that is able to allow the passage of electricity and heat without resistance.

  • In superconductors, under certain conditions, resistance ceases to exist.
  • Examples are aluminium, niobium e.t.c
  • A conductor allows heat and current to pass through but with little resistance.
