Answer:

It is all about the tilt of the Earth's axis. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!

If a planet rotates 360 degrees during a 24 hour time period, what does that tell us about the planet? A. The middle of the plan
vlabodo [156]

The correct answer is C

<u />

<u>Explanation:</u>

360-degree rotation of the planet in 24 hours causes a 12-hour time clock. The earth rotates on its own axis and around the sun.

It completes one rotation on its own axis in 24 hours equal to 360 degrees which make one complete solar day. The part of the earth which is exposed to the sun has daytime while the other part experiences the night time.

<span>An element belonging to the halogen family would be expected to have a large ionization energy and a large electron affinity.
Flourine, Chlorine, Bromine, Iodine and astatine are the elements that belongs to the halogen family and mostly they have high values of ionization energy. 
The amount of energy released when an electron is added to an atom or molecule to form a negative ion or anion is electron affinity.</span>Chlorine from this family has highest electron affinity.

Answer:

NiS insoluble

Mg₃(PO₄)₂ insoluble

Li₂CO₃ soluble

NH₄Cl soluble

C₁₂H₂₂O₁₁ molecules

Explanation:

<em>Predict whether the following compounds are soluble or insoluble in water.</em>

Based on the solubility rules we can say:

  • NiS: Sulfides of transition metals are highly insoluble.
  • Mg₃(PO₄)₂: All phosphates (except those with metals of Group 1) are insoluble so Mg₃(PO₄)₂ is insoluble.
  • Li₂CO₃: all salts of metals of Group 1 are soluble so Li₂CO₃ is soluble.
  • NH₄Cl: all salts of ammonium are soluble so NH₄Cl is soluble.

<em>Which of the following best describes the solute in an aqueous solution of sucrose or C₁₂H₂₂O₁₁(aq)?</em>

Sucrose is a molecular compound in which atoms are linked through covalent bonds. Thus, it does not ionize in water (is a non-electrolyte) and when it dissolves it exists as C₁₂H₂₂O₁₁ molecules.
