Answer: (4) the energy released or absorbed during the reaction

Explanation: Potential energy diagram is the representation of energy with the course of reaction. It shows the energy of reactants, activation energy which is the energy required by the reactants to cross the energy barrier and the energy of the products.

Thus the difference of energy of products and energy of reactants gives us the energy released or absorbed during the reaction.

\Delta H=E_P-E_R

where \Delta H = enthalpy of reaction

E_P = energy of products

E_R = energy of reactants

If E_P > E_R , energy is absorbed and reaction is endothermic

E_P < E_R , energy is released and the reaction is exothermic.

Where are the most reactive nonmetal elements found on the periodic table?
Varvara68 [4.7K]

Answer is: group 17 on the periodic table.

Group 17 (halogens) elements are: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I).

They are very reactive and easily form many compounds.  

Fluorine and chlorine are in gaseous state, bromine is liquid and iodine is in solid state in room temperature.

Halogens need to gain one electron to have electron cofiguration like next to it noble gas.

For example, fluorine has 9 electrons and it gain easily one electron in chemical reaction to have electron configuration like noble gas neon (Ne) with 10 electrons.

If 420 joules of heat energy is added to 25 grams of water at 25 degrees celcius, what will be the final temperature of the wate
natka813 [3]

Answer:

T2 = 29°C

Explanation:

Given data:

Heat added = 420 j

Mass of water = 25 g

Initial temperature = 25°C

Final temperature = ?

Solution;

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Specific heat capacity of water = 4.18 j/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Now we will put the values.

420 j = 25 g ×4.18 j/g.°C × (Final temperature - initial temperature)

420 j = 25 g ×4.18 j/g.°C × (T2 - 25°C)

420 j = 104.5  j/°C × (T2 - 25°C)

420 j /104.5  j/°C = T2 - 25°C

4°C + 25°C = T2

T2 = 29°C
