7 0

Answer:

Explanation:

57.1 g of oxygen combines with 42.9 g of carbon

57.1/16 atoms of oxygen combines with 42.9 / 12 atoms of carbon

3.56 atoms of oxygen combines with 3.575 atoms of carbon

one atom of oxygen combines with one atom of carbon

A appears to be CO ( carbon monoxide gas )

2 )

72.7 g of oxygen combines with 27.3 g of carbon

72.7 / 16 atoms of oxygen combines with 27.3 / 12 atoms of carbon

4.54 atoms of oxygen combines with 2.275 atoms of carbon

2 atoms of oxygen combines with 1 atom of carbon

B appears to be CO₂ ( Carbon dioxide)

¿Cuál es la diferencia entre electrones internos y electrones externos? *
Fudgin [204]

Answer & Explanation:

Los electrones externos se encuentran más lejos del núcleo. El número de electrones en la capa más externa (electrones de valencia) de un átomo en particular determina su reactividad (tendencia) a formar enlaces químicos con otros átomos.

Los electrones internos son los más cercanos al núcleo. Protegen los electrones de valencia del núcleo, reduciendo la carga nuclear efectiva.

These little bunnies (A, B, and C) were born in the same litter to the same parents, but they have different traits for the feat
marta [7]

Answer:

Due to random assortment and incomplete dominance of alleles.

Explanation:

The bunnies end up with ear thicknesses that are different from one another due to random assortment of alleles during gamete formation according to Mendel.

In addition to random assortment, the allele for thick ear also displayed what is known as incomplete dominance over the allele for thin ear to arrive at an average ear thickness.

C(s) + S8(s) → CS2(l)
Vanyuwa [196]
The balanced chemical reaction is written as:

<span>4C(s) + S8(s) → 4CS2(l)

We are given the amount of carbon and sulfur to be used in the reaction. We need to determine first the limiting reactant to be able to solve this correctly.

</span>7.70 g C ( 1 mol / 12.01 g) =0.64 mol C
19.7 g S8 ( 1 mol / 256.48 g) = 0.08 mol S8

The limiting reactant would be S8. We use this amount to calculate.

0.08 mol S8 ( 4 mol CS2 / 1 mol S8 ) ( 256.48 g / 1 mol ) = 78.8 g CS2
