The change in enthalpy for the reaction of carbon dioxide is -393.5 kJ/mol. Thus, option A is correct.
The change in enthalpy of the reaction is given by the energy of the product and the energy of reactant difference.
The chemical equation for the reaction is:
<h3>Computation for the enthalpy change</h3>
The standard enthalpy change for carbon dioxide is -393.5 kJ/mol
The standard enthalpy change for oxygen is 0 kJ/mol
The change in enthalpy of reaction is given as:

Answer:
Part 1: 2KNO3 → 2KNO2 + O2 is the balanced equation.
Part 2: The conversation of mass that demonstrates that there is no detectable change in the total quantity of matter present in the
Explanation:
Part 1: To balance a chemical equation, the number of atoms in the reactants and the products must be equal. So, the coefficient 2 added before KNO3 and KNO2 to balance the equation.
2KNO3 → 2KNO2 + O2
Part 2:
This chemical reaction demonstrates the conversation of mass that demonstrates that there is no detectable change in the total quantity of matter present when chemical change occurs (matter converts from one type to another) or physical change occurs (changes among solid, liquid, or gaseous states).
This is clear in the balanced equation.
Electric current is when electrons start to flow around a circuit. We use an ammeter to measure it and it is measured in amps
Potential difference (also called voltage) is how big the push on the electrons is. We use a voltmeter to measure it and it is measured in volts.
Resistance is anything that resists an electric current. It is measured in ohms”.
(Words: volts, amps, ohms, voltage, ammeter, voltmeter).
D all of these I’m about 99% sure
Answer:
The kinetic particle theory explains the properties of the different states of matter. The particles in solids, liquids and gases have different amounts of energy. They are arranged differently and move in different ways.
