Wind direction is reported by the direction from which it originates. For example, a north or northerly wind blows from the north to the south. Wind direction is usually reported in cardinal (or compass) direction, or in degrees.

Doss [256]
The balanced chemical reaction is:

<span>Ca + Cl2 =  CaCl2
</span>
We are given the amount of calcium metal to be used for this reaction. This will be the starting point for the calculations.

56 g Ca ( 1 mol Ca / 40.08 g Ca) (1 mol Cl2 / 1 mol Ca) ( 22.414 L Cl2 / 1 mol Cl2 ) = 31.32 L Cl2 gas produced from the reaction

Answer:

<u><em>The correct option is C) the moon takes the same time to rotate and revolve.</em></u>

Explanation:

Scientific experiments have concluded that it takes approximately 23 days for the moon to rotate and also it takes the same duration for the moon to revolve around the Earth. Due to this consistency, the moon appears to be still.

<em>Such synchronization results in the same face of the moon to be directed towards the Earth. Hence, the same craters of the moon will be observed by the scientist every day.</em>

<em></em>

Other options, like option D, is not correct because there will be craters on the other side of the moon too. But as we see the same side of the moon, hence we cannot see the craters present on the other side of the moon.

<h2>Ionic bonds result from transferring of electrons</h2>

Explanation:

  • Ionic bonds result from transferring of electrons.
  • An ionic bond is also referred to as an electrovalent bond.
  • The main reason for the formation of the bond is an electrostatic attraction between oppositely charged ions that are cation and anion in a chemical compound.
  • The formation of such bonds occurs when the valence (outermost) electrons of one atom are transferred to another atom or the loss of electrons from one atom and gain of electrons of another atom.
  • The atom that loses the electrons forms cation that is a positively charged ion.
  • The atom that gains electrons forms an anion that is a negatively charged ion.
