Nitrogen and oxygen form an extensive series of oxides with the general formula NxOy. One of them is a blue solid that comes apa
Marizza181 [45]

Work out the number of moles in

100.00 grams of the oxide.

For nitrogen: The atomic mass of N is 14.0067, and we have 36.84 g N:

36.84 g N14.0067 g N/mol N=2.630 mol N

For oxygen: The atomic mass of O is

15.9994, and we have

100.00−36.84=63.16 g O:

63.16 g N 15.9994 g N/mol N=3.948 mol N

Now the ratio 3.958 2.630 is very close to

1.5=32

. So we conclude that the gas has three moles

O to two moles N making the empirical formula

N2O3.

Why the copper is able to replace the silver, but the reverse reaction will not result in a replacement reaction?
PSYCHO15rus [73]

Answer:

Copper is more reactive and higher in the activity series

Explanation:

Copper is able to replace the silver in a replacement reaction because it is more reactive and higher in the activity series.

Substances or ions that are higher in the activity series are typically more reactive than those ones below them.

In like manner, they are able to replace the lowers ones in a chemical reaction due to their higher reactivity potential.

A less reactive element and a lower one in the activity series cannot displace a higher one in the series.

Chlorine (cl) has an atomic number of 17. it often forms an ion by gaining 1 electron. what would its charge be?
Aliun [14]

Answer:

= -1

Explanation:

  • Chlorine belongs to the halogen group in the periodic table. It has an atomic number of 17, which indicates the number of protons and electrons in a neutral atom of chlorine is 17.
  • Therefore; with an atomic number of 17, its electronic configuration will be 2:8:7.
  • Thus; to attain a stable configuration chlorine requires to gain one electron, by so doing it becomes a negatively charged ion with a charge of -1.
