LenaWriter [7]

Answer:

6.49g

Explanation:

Let's consider the balanced reaction for photosynthesis.

6 CO₂ + 6 H₂O = C₆H₁₂O₆ + 6 O₂

We can establish the following relations:

  • 1 mole of CO₂ has a mass of 44.01 g (MW 44.01)
  • The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1.
  • 1 mole of C₆H₁₂O₆ has a mass of 180.16 g/mol.

The mass of glucose produced by the reaction of 9.51 g of carbon dioxide is:

9.51gCO_2 \times \frac{1molCO_2}{44.01gCO_2}  \times \frac{1molGlucose}{6molCO_2}  \times \frac{180.16gGlucose}{1molGlucose} = 6.49g Glucose

Un átomo X posee 29 protones y de carga +2 ¿Cuántos electrones tiene?
lesya [120]

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
