Basically what we are trying to do here is see if we are going from molecules to moles or moles to molecules.
We know that avogadro's number is 6.022x10^23 molecules in 1 mol of anything.
So if the questions asks you to convert moles to molecules just multiply it by avogadro's number
If the question asks you to convert molecules to moles just divide by avogadro's number
Answer:
it adds to scientific knowledge
There's a force that acts on the particulate matter that keeps it together. This proves that attraction varies from particles of one substance to another.
Answer:
KCl
Explanation:
Look at the electronegativity differences between the pairs of elements:
KCl: 3.16 - 0.82 = 2.34
BeCl: 3.16 - 1.57 = 1.59
LiCl: 3.16 - 0.98 = 2.18
ClO: 3.44 - 3.16 = 0.28
KCl has the highest electronegativity difference; thus it is the most ionic bond of the 4.
Se producirán 36 gramos de agua
Explicación: Ya que en una reacción química no puede descubrir ningún cambio en masa total de las sustancias que en ella intervienen, pues en una reacción química ni se gana ni se pierde masa.
