Answer:
51.66 mol H2O (steam)
Explanation:
5.74 mol C3H18 x 18 mol H2O/ 2 mol C3H18 = 51.66 mol H2O (steam)
Answer:
The number of moles of H₂O is 0.135 mol.
The number of moles of LiClO₄ is 0.0449 mol.
Explanation:
Mole is an important standard unit used for the measurement of large quantities of atoms, molecules, or other particles. One mole is equal to 6.022×10²³ units.
The number of moles of a substance is calculated by:
To find the number of moles of H₂O:
Mass of H₂O in the sample = 2.43g
The molecular weight of H₂O = 18.02g
Number of moles = 
= 0.135 mol.
To find the number of moles of LiClO₄:
Mass of LiClO₄ given = 4.78g
The molecular weight of LiClO₄ = 106.39g
Number of moles = 
= 0.0449 mol.

Answer:
D
Explanation:
B is solid and liquid while D is liquid and gas
C.) a substance with a low ability to conduct energy
Explanation:
The statement that best defines insulators is that it is a substance that has low ability to conduct energy.
Insulators resist the movement of mostly electrical and thermal energy.
They have unique properties that makes them so.
- Insulators are substances that do not conduct heat and electricity.
- Both their solid and molten form lacks the capability of electrical and thermal conduction.
- Some substances can only conduct when molten or liquid.
- Conductors are materials that allows for the passage of electrical and heat energy.
- Most conductors are usually salts, ionic compounds and metals.
- Non-conductors like insulators are usually plastics and woods.
