Answer:
116,823 J
Explanation:
formula : q=m C delta T
q = heat = unknown
mass = 100 g
C = specific heat = 4.2 J/K*g
delta T = temperture in Kelvins: 5 + 273.15 = 278.15 K
q = (100 g) ( 4.2 J/K*g) (278.15 K) = 116,823 J
Answer:
2.83mole of Cl
Explanation:
Equation of reaction:
Na + Cl -----> NaCl
Since 1 mole of Na react with 1 mole of Cl from the equation. Then 2.83mole of Na will react with 2.83mole of Cl
