Answer:
it holds reactant molecules in a good position for then to react
Answer:
first we add the same direction. 12N + 32 N=44N .
then we add the forces. 54 up + 44N down= 10N up
Answer:
not goin to be rude but I don't even get the question??
Answer:
7.22 x 10²³molecules
Explanation:
Given parameters:
Number of moles of hydrogen = 1.2moles
Unknown:
Number of molecules of hydrogen = ?
Solution:
From the concept of moles, a mole of a substance contains the Avogadro's number of particles.
1 mole of a substance = 6.02 x 10²³ molecules;
So; 1.2 moles of hydrogen = 1.2 x 6.02 x 10²³ molecules;
= 7.22 x 10²³molecules
