Elements in group 16 want to bond with elements in group ___.
Trava [24]

Answer:

Two

Explanation:

Elements in group 16 wants to bond with elements in group IIA, the group of alkaline earth metals.

  • The bonding will make it easier for them complete their octet.
  • Elements in group 16 has 6 valence electrons.
  • To have a complete octet, they require 2 more electrons.
  • Group II elements are willing donors as they are metals.
  • For Group II elements to fill their octets, they must lose two electrons.
  • So the willingness of group II elements to lose two electrons and the readiness for group 16 elements to gain the electrons makes the desire one another.

Chemist A burns 10.000 grams of C₂H₆ in a constant-volume container at 25ºC. Chemist B burns an unknown mass of C₂H₆ in a consta
alexandr1967 [171]

Answer:

10.000 grams

Explanation:

For the first law of thermodynamics, the energy must be conserved, that means that the energy in form of heat (Q) must be equal to the sum of work (W) and internal energy(ΔU) :

Q = W + ΔU

ΔU depends on the temperature and W in the variation of pressure and volume. Q depends on the temperature, but also the mass. So, there is the same temperature, ΔU is equal for both reaction, if there is no work done, the heat must be equal for both of them. So the mass such be the same.
