I hope this helps you with your problem !!!!!
This undergoes both oxidation and reduction. This reaction is
a kind of chemical reaction that includes a transmission of
electrons between two species. An oxidation-reduction reaction is
any chemical reaction in which the oxidation number
of an atom, molecule, or ion fluctuates by attaining or dropping an electron.
Answer:
An ionic bond is the electrostatic force that holds ions together when they form bonds
Explanation:
An ionic bond is formed when a metal looses electron(s) to a non metal leading to the formation of a positive ion and a negative ion.
An ionic compound is actually an ion pair, the ions are held together by strong electrostatic forces.
This strong electrostatic force that holds the ion pair together in ionic compounds is what we commonly call the IONIC BOND.
The chemical equation for photosynthesis is carbon dioxcide + water then sunlight = glucose and oxygen
Answer: The final energy is 1,700 J
Explanation: According to first law of thermodynamics:
=Final energy-initial energy=Change in internal energy
q = heat absorbed or released
w = work done by or on the system
w = work done by the system=
{Work done by the system is negative as the final volume is greater than initial volume}
q = +500J {Heat absorbed by the system is positive}
w = work done by the system = -300J
