<h3>Answer;</h3>
= 13.629 g of ZnCl2
<h3><u>Explanation;</u></h3>
The equation for the reaction.
Zn(s)+2HCL(aq)=>ZnCl2(aq)+H2(g)
Number of moles of Zinc;
Moles = mass/RAM
= 6.5 g/65g/mol
= 0.1 moles
The mole ration of Zn : ZnCl2 is 1 : 1
Therefore, number of moles of ZnCl2 is 0.1 moles
Mass = moles × Molar mass
= 0.1 ×136.286 g/mol
<u> = 13.629 g</u>
Answer:
Exotérmica.
Explanation:
¡Hola!
En este caso, dado que la mayoría de reacciones de combustión son exotérmicas, al generar calor en los productos, es posible inferir que esta reacción, referida a la combustion de metano es exotérmica debido a lo anteriormente mencionado, ya que el término de energía de reacción, 531 kcal, está al lado de los productos, lo que quiere decir que es energía generada.
¡Saludos!
<h3>The somatic and sex chromosomes mainly differ in their Ploidy.</h3>
- Somatic Chromosomes are Diploid (2n)
- Sex Chromosomes are Haploid (n)
Haploidity of sex chromosomes enables the formation of a diploid zygote after fertilization
<h3>Somatic Chromosomes are homologous in nature while the Sex Chromosomes can be Analogous as in the case of Spermatozoa which bears XY genes </h3>
Answer: 26.7 moles
Explanation: 
As can be seen from the balanced chemical equation 2 moles of hydrogen combine with 1 mole of oxygen to give two moles of water.
1 mole of oxygen give = 2 moles of water.
Thus 13.35 moles of oxygen give=
of water.
Explanation:
1)observation is that the light doesn't reach some parts of the points of interest
2)this is because the rays of the light were interrupted by different objects thus making the light divert different ways.
