Answer:
The number of electron domains in a molecule or ion is the number of bonds (double and triple bonds count as one domain) plus the number of nonbonding (lone) electron pairs.
Explanation:
Answer:
2.408x10^24 molecules
Explanation:
1mole of a substance contains 6.02x10^23 molecules.
This means that 1mole of C3H8 contains 6.02x10^23 molecules.
Therefore, 4moles of C3H8 will contain = 4 x 6.02x10^23 = 2.408x10^24 molecules
Answer:
Explanation:
Florida is much closer to the sun as compared to New York and seems to be much warmer as compared to New York even in winter and summer because of the latitude.

Responder:
27
Explicación:
Dado que:
Número de protones en el átomo X = 29
Carga en el átomo X = +2
Si no hay cargo neto;
número de protones = número de electrones
Sin embargo, dado que el átomo X tiene una carga de +2 (dando 2 electrones).
Por lo tanto,
Número de electrones = número de protones - número de carga en el átomo)
Número de electrones = (29 - 2) = 27
