8S or S8 but it is not 8S8
8S8 does not make senes
Beside, is this element is existed.
It means that u have 64 molecules of Sulphur.
Answer:
The correct answer is "Temperature is a measure of the average kinetic energy of the molecules in a substance".
Explanation:
The kinetic energy of a substance is defined as the power that results from the movement of its particles. In this sense, temperature could be defined as a measure of the average kinetic energy of the molecules in a substance. Actually, temperature expressed in Kelvin degrees is directly proportional to the average of the kinetic energy. On the other hand, heat is defined as the total energy in a substance.
1. Given the following equation: N2 (g) + 3 H2 (g) ↔ 2NH3 (g) ΔH = -92 kJ/mol
a. this reaction is exothermic as ΔH is -ve
b. the equilibrium will shift 2 the left if nitrogen gas is removed
c. the equilibrium shift 2 the right if the temperature is lowered
d. the equilibrium shift 2 the left if ammonia (NH3) is added
e. principle of thermodynamic potential or Gibbs energy is used to answer B-D
Al (1s²2s²2p⁶3s²3p¹) - 3e⁻ → Al³⁺ (1s²2s²2p⁶)
3s²3p¹
