Contained within a system that is responsible for it temperature
The correct option is D.
An endothermic reaction is a type of reaction that absorb energy from the environment, thus, the energy level of the product is always higher than that of the reactants. During endothermic phase change, the potential energy of the system always increases while the kinetic energy of the system remains constant. The potential energy of the reaction increases because energy is been added to the system from the external environment.
Number of neutrons = atomic mass - atomic number = 56-26 = 30
Answer:
Multivalent Ionic
Explanation:
The type of bond formed between the atoms of two elements can easily be deduced from the magnitude of electronegativity difference between the two bonding atoms.
A summary of electronegativity differences and corresponding types of bonds are shown below as adapted from chemlibretexts, where Δχ is the difference in electronegativity ;
ionic if Δχ ≥ 2.0
polar if 2.0 > Δχ > 0.5
nonpolar if 0.5 > Δχ
To determine the type of bond between Hg and F. Hg has an electronegativity of 2 while F has an electronegativity of 4. the difference in electronegativity (Δχ) is 4 - 2 = 2
This corresponds to a multivalent ionic bond because mercurous ion is the
Hg2^2+ ion and this leads to the formation of Hg2X2 (mercury I fluoride).
Answer:
Your answer is Plasma which is D.
Explanation:
This is because lighting can be structed in the sky near stars or sun.
