Answer:

4. Principal and Azimuthal (subsidiary) quantum number

5.Principal, Azimuthal (subsidiary), and magnetic quantum number

6. 10 electrons

7. 32 electrons

8. 36 electrons

Explanation:

4. Principal and Azimuthal (subsidiary) quantum number because in 4d, 4 represent principal quantum number and d- represents azimuthal quantum number (having l- value as 3)

5.Principal, Azimuthal (subsidiary), and magnetic quantum number are the first three because 2 stands for principal, s-for azimuthal (l=0) and magnetic quantum number for s- orbital= 0

6. 10 electrons, because for sublevel with l= 3, is a d-sub-level, and d- can take 10-electrons

7. 32 electrons, using the relationship 2×n^2 for the maximum number of electrons in a shell,

,n= 4 , hence 2×4^2= 32

8. 36 electrons, because n=4 and n= 3 can have the maximum configuration of [Ar]4s^2 3d^10 4p^6

This will sum up to 36- electrons, since Argon has 18 -electrons.

18+2+10+6=36 electrons

calculate the volume of air in liters that you might inhale(and exhale)in 8.0 hours. Assume that each breath has a volume of 0.5
maks197457 [2]
Formula:
0.57 liters = 1 breath(17 breaths = 1minute)(60 minutes = 1 hour)(8 hours) = 4651.2 liters

each breath is 0.57 liters
He or she exhales 17(0.57) = 9.69 liters in a minute
in an hour, he or she exhales 9.69(60) liters in a minute = 581.4 liters
Answer = in 8 hours he or she exhales, 581.4(8) = 4651.2 liters in 8 hours


Hope that answers your question!!!!have a great day!!!

Write the skeleton equation for the reaction which occurs when a solution of silver nitrate reacts with copper metal to produce
Kitty [74]

Answer:

This reaction can be expressed as a word equation: copper + silver nitrate → silver + copper nitrate You can replace each part of the word equation by a chemical formula: Cu + AgNO3 → Ag + Cu(NO3)2 Looking at both sides of this equation, you can see that it is not balanced.

There are several ways to model a compound. One type of model is shown.
yawa3891 [41]

Answer: The chemical formula for the formula given in the image is C_4H_9O_2.

Explanation: There are many ways in which a model can be represented:

  1. Molecular Formula
  2. Ball and Stick formula
  3. Expanded Formula
  4. Condensed Formula
  5. Skeletal Formula

This molecule is represented by the Expanded Structural Formula and by seeing in the image we can count the number of each element present.

Number of Carbon atoms present = 4

Number of Hydrogen atom present = 9

Number of Oxygen atom present = 2

Correct representation for this will be C_4H_9O_2.
