This is a science multiple choice question. I am posting this for the third time because the people who answered it posted a lin

k and when I copied and pasted it to see the answer, it didn't work so please answer correctly without A LINK! Please whoever answers this without posting a link to the answer will be marked brainliest.
I appreciate it, thanks.

I believe the answers would be continental drift, sea floor spreading, and lithosphere.

All of these have something to do with plate tectonics.

Calculate the number of atoms in a 5.31 x 10³ g sample of sodium.<br><br> number of atoms:
Leviafan [203]

Answer:

        no of atoms =   13.9 x 10^25

Explanation:

                No. of moles = mass of compound / molar mass of   compound

   

       As ; mass of sodium = 5.3 x 10^3 g

       

        Molar mass of sodium = 22.9 g/ mol

         

        putting values  

         

         n = 5.3 x 10^3 / 22.9

       

         n = 231.4 mol

Also; no of mol (n) = no of particles / Avagadros number

               so no of particles = n x Avagadros no.

     

               put n = 231.4 and Avagadros no = 6.023 x 10^23

 

                 no of particles = 231.4 x 6.023 x 10^23

                                   =   13.9 x 10^25

How does Earth's rotation affect ocean currents?
Tom [10]

Answer:

Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.

How many carbon dioxide (CO2) molecules are produced during the decomposition of 1.25 moles of Carbonic acid (H2CO3)? ****Rememb
Andreas93 [3]

Answer:

7.53×10²³ molecules

Explanation:

Given data:

Number of moles of carbonic acid =  1.25 mol

Number of molecules of CO₂ produced = ?

Solution:

Chemical equation:

H₂CO₃   →     CO₂ + H₂O

Now we will compare the number of moles of carbonic acid with CO₂ from balanced chemical equation.

                                 H₂CO₃      :        CO₂

                                    1             :           1

                                   1.25         :       1.25

Number of molecules can be determine by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

Number of molecules:

1 mole = 6.022 × 10²³ molecules

1.25 mol ×  6.022 × 10²³ molecules  / 1 mol

7.53×10²³ molecules
