hope this helps and mayb a brinaly? and if i get this wrong go to my pf and i will answer at least ten quesstions free!
Answer:
The substance has a specific heat of 1.176 J/g°C
Explanation:
<u>Step 1: </u>Data given
Temperature change = 34 °C
Mass of the substance = 20 kg = 20000 grams
The substance gained 800 kJ of heat during this temperature change
<u>Step 2:</u> Calculate the specific heat
q = m*c*ΔT
⇒ with q = heat gained = 800 kJ = 800000 J
⇒ with m = the mass of the substance = 20 kg = 20000 grams
⇒ with c = the specific heat of the substance = TO BE DETERMINED
⇒ with ΔT = the change of temperature = T2 -T1 = 48° - 14 ° = 34°
c = q/(m*ΔT)
c = 800000 / (20000 * 34)
c = 1.176 J/g°C
The substance has a specific heat of 1.176 J/g°C
In the reaction, fluorine and chlorine are present as reactants. Fluorine is a stronger oxidizing agent than chlorine, as fluorine has the tendency to be reduced. Keep in mind that oxidation is when there is an increase in the oxidation number of a substance and reduction is when there is a decrease in the oxidation number. Therefore, the correct statement becomes:
Cl- oxidizes to Cl and F reduces to F-.

Explanation:
magnesium is not a good conductor has some free electrons but it is not used that much in the industries because of other better alternatives.
