Answer:

d. the new moon at perigee coming between Earth and the sun along a straight line

Explanation:

Solar eclipse occurs when moon comes in between sun and Earth and the three align in a straight line. The moon blocks the sunlight falling on the earth. The earth passes through the shadow of the moon.This phase of moon is New moon.

A total eclipse is said to occur when the disc of moon complete covers the disc of sun. This happens when moon is at closest position to earth in it orbit that is at perigee.

Discuss the shapes of s- orbitals, p-orbitals and d-orbitals.
timurjin [86]

The azimuthal quantum number (l) determines its orbital angular momentum and describes the shape of the orbital.

s-orbitals (for example 1s, 2s) are spherically symmetric around the nucleus of the atom.

p-orbitals are dumb-bell shaped. l = 0,1...n-1, when l = 1, that is p subshell.

d-orbitals are butterfly shaped.

State the guideline you can use to predict the formula of:
Cerrena [4.2K]

We can predict formula of ionic compounds by:

  • Take a look at where the elements are listed on the periodic table.
  • The amount of electrons that an element would need to gain or lose in order to resemble an atom of a nearby noble gas is one of the similarities that atoms in the same column as one another (group) tend to display.
  • Alkali metal group I ions have +1 charges.
  • Alkaline earth metals (group 2 ions) have a +2 charge.
  • Nonmetal group 6 ions have a charge of -2.
  • Halides in group 7 have a -1 charge.
  • The charges of the transition metals cannot be predicted in a straightforward manner.
  • Check out a table of charges (valences) to see potential values. The +1, +2, and +3 charges are most frequently employed in beginning and general chemistry courses.
  • Keep in mind that the positive ion is always stated first when writing an ionic compound's formula.

These are the few guidelines we can use to product formula.

What is the complete balanced equation for the reaction that occurs when lithium carbonate (Li2CO3) is heated?
Fed [463]
When heating lithium carbonate (Li2CO3), it will dissociate to Li2O and Co2. So the balanced chemical equation of this reaction is Li2CO3 = Li2O + CO2.
