A substance conducts an electric current when it is in the liquid state. What would the conductivity of the substance in solid form indicate about the type of bond in the substance?A.) If the solid is conductive, the bonds are ionic.
B.) If the solid is not conductive, the bonds are covalent.
C.) If the solid is conductive, the bonds are metallic.
D.) If the solid is not conductive, the bonds are metallic.

Answers

Answer is: C.) If the solid is conductive, the bonds are metallic.

1) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.

2) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.

3) Substances with metallic  bond conduct an electric current in liquid and solid state, because they have mobile electrons. Most metals have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

Answer:C.) If the solid is conductive, the bonds are metallic.

Explanation:

Compared to a 0.1 M aqueous solution of NaCl, a 0.8 M aqueous solution of NaCl has a(1) higher boiling point and a higher freezing point
(2) higher boiling point and a lower freezing point
(3) lower boiling point and a higher freezing point
(4) lower boiling point and a lower freezing point

Answers

Answer 2, because when you add salt to something, it cools faster (ex. When you add salt to an ice chest so that it stays cold) and it takes longer to boil (ex. When you boil salt out of ocean water so that its safe to drink) therefore, the more NaCl in the solution, the more it will exibit these properties

What biome could be characterized by large evergreen trees, acidic soil, lichens, and heavy winter snowfall?

Answers

The biome that could be characterized by large evergreen trees, acidic soil, lichens, and heavy winter snowfall is TAIGA. The Taiga experiences extremely cold or hot weather conditions. This is why the main seasons in the taiga are summer and winter. It is actually the largest biome in the world, and is located at the tip of Eurasia up to North America.

Answer:

Taiga

Which statement describes an alternate theory of acids and bases?(1) Acids and bases are both H+ acceptors.
(2) Acids and bases are both H+ donors.
(3) Acids are H+ acceptors, and bases are H+ donors.
(4) Acids are H+ donors, and bases are H+ acceptors.

Answers

Answer: Option (4) is the correct answer.

Explanation:

According to Bronsted and Lowry, acids are the species which can donate hydrogen or H^(+) ions.

Whereas bases are the species which can accept hydrogen or H^(+) ions.

Thus, we can conclude that the statement acids are H^(+) donors, and bases are H^(+) acceptors describes an alternate theory of acids and bases.
The answer is (4) Acids are H+ donors, and bases are H+ acceptors. This constitutes the Bronsted-Lowry theory of acids and bases.

20 g of sugar is stirred into a beaker containing 100 g of water. After the sugar has completely dissolved, the solution is put on a scale. What is the mass of the solution?

Answers

The mass of the solution of sugar and water is 120 grams.

What is mass?

Mass is the quantity of matter of a physical body.

The mass of the sugar is given is 20g

The mass of the water is 100 g.

100 + 20 = 120 gram

Thus, the mass of the solution of sugar and water is 120 grams.

#SPJ2
The mass of the solution should be 120g since 20g of sugar were added to 100g and 100+20=120.
