Answer:
1.07 ×10² j/g.°C
Explanation:
Given data:
Mass of substance Z = 13.5 g
Amount of heat absorbed = 36 Kj (36×1000 = 36000 j)
Increase in temperature= ΔT = 25°C
Specific heat of substance = ?
Solution:
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 in formula.
Q = m.c. ΔT
36000 j = 13.5 g ×c×25°C
36000 j / 13.5 g×25°C = c
c = 36000 j /337.5 g.°C
c = 1.07 ×10² j/g.°C
Your answer would be C.
Platinum is consider one of the 12 most common native elements.
Hydrochloric acid reacts with sodium hydroxide to form sodium chloride (the salt) and water. Sodium chloride is made up of Na+ cations from the base (NaOH) and Cl- anions from the acid (HCl). HCl+NaOH→H2O+NaCl.
