Answer:

C) Sugar solution is a separable mixture but steel is an inseparable mixture.

Explanation:

Sugar can be put in water then have the water dried out and there will be sugar. Metal how ever can not be a separable mixture without making it into a liquid.

The combustion of ethane ( C 2 H 6 ) produces carbon dioxide and steam. 2 C 2 H 6 ( g ) + 7 O 2 ( g ) ⟶ 4 CO 2 ( g ) + 6 H 2 O (
grigory [225]

Answer:

10.6 moles of CO₂ are produced in this combustion

Explanation:

The combustion reaction is:

2C₂H₆ (g) + 7O₂ (g) ⟶ 4CO₂ (g) + 6H₂O (g)

We assume the ethane as the limiting reactant because the excersise states that the O₂ is in excess.

We make a rule of three:

2 moles of ethane can produce 4 moles of CO₂

Therefore 5.30 moles of ethane will produce (5.3 . 4) /2 = 10.6 moles

For each solute identify the better solvent: water or carbon tetrachloride <br> Na2, I2, CCH2O, C6H6
Virty [35]
NH3 = water (it is actually a water soluble gas)
C6H14 = CCl4 (C6H14 won't mix with water at all)
Na2S = water (Na2S is a salt. Salts dissolve best in water)
Br2 = CCl4, but it will also dissolve in water.

A nonmetal in the third period that should have chemical properties similar to oxygen.
Fantom [35]

Answer:

Sulfur

Explanation:

A non-metal in the third period that should have chemical properties similar to oxygen is sulfur.

This is because elements in the same group/family have similar chemical properties.

  • Chemical properties is predicated on the number of valence electrons within an atom.
  • The number of valence electrons is the number of outermost shell electrons within an atom.
  • Elements combines with one another using these valence shell electrons.
  • Since sulfur is in the third period and the same vertical group as oxygen, they have similar chemical properties.
