Answer:

Organisms change their behavior in response to changes in the surrounding environment.

Explanation:

All living things can respond to stimuli in the exterier environment, It is a form of energy—light waves or sound vibrations, From what they sense they will make neccisary changes to their diet and or where they are located.

Such as winter weather which is a type of stimulus will cause some animals to start hibernating.

Balance the following reaction:
miv72 [106K]

 The balanced reaction is   as below

3A₂B  + 2DC₃→ 6 AC  + D₂B₃


The number that must be  to the left of AC   is 6

 Explanation

  • According to the law  of mass  conservation , the number of atoms in reactant side   must be equal  to number  to the number of atoms  in  product  side.
  • Therefore the equation above is balance  since  it obey the law of mass conservation.
  • For example there is 6 atoms  of A in reactant side and  6 in product side.

Use the periodic table to determine the electron configuration for Ca and Pm in noble-gas notation Ca: [Ar]4s2 [Ar]4s1 [Ar]3s2 [
sveta [45]
Answer:

1) Ca: [Ar]4s²
2) Pm: [Xe]6s²4f⁵

Explanation:

1) Ca:

Its atomic number is 20. So it has 20 protons and 20 electrons.

Since it is in the row (period) 4 the noble gas before it is Ar, and the electron configuration is that of Argon whose atomic number is 18.

So, you have two more electrons (20 - 18 = 2) to distribute.

Those two electrons go the the orbital 4s.

Finally, the electron configuration is [Ar] 4s².

2) Pm

The atomic number of Pm is 61, so it has 61 protons and 61 electrons.

Pm is in the row (period) 6. So, the noble gas before Pm is Xe.

The atomic number of Xe is 54.

Therefore, you have to distribute 61 - 54 = 7 electrons on the orbitals 6s and 4f.

The resultant distribution for Pm is: [Xe]6s² 4f⁵.
