Answer:it is 3 just look at the middle numbers
Explanation:
Answer:

Explanation:
Hello!
In this case, since the heat of vaporization is related with the energy required by a substance to undergo the phase transition from liquid to gas, we can compute such amount of energy as shown below:

In such a way, since the enthalpy of vaporization is given as well as the mass, we compute the energy as shown below:

Best regards!
Answer:
B) FALSE.
Explanation:
First off, its important to understand the following concepts;
A half reaction is either the oxidation or reduction reaction component of a redox (Oxidation - Reduction) reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction.
Often, the concept of half-reactions is used to describe what occurs in an electrochemical cell, such as a Galvanic cell battery. Half-reactions can be written to describe both the metal undergoing oxidation (known as the anode) and the metal undergoing reduction (known as the cathode).
Half equations simply much just breaks the reaction into oxidation and reduction steps (irrespective of the order, whether left or right).
An example of half equation is given below;
Mg → Mg2+ + 2e− (Oxidation)
Cu2+ + 2e− → Cu (Reduction)
The answer is false because; oxidation-reduction reactions are NOT represented by equations that group the reaction participants into reactants and products. Rather they are
Answer:
i think b is the answer hope this helps:))
