Answer:
2Ag (s) + 2HNO3 (aq) → 2AgNO3 (aq) + H2(g)
Explanation:
Usually, metals displace hydrogen from dilute acids to form the corresponding salt of the metal and hydrogen. This in turn depends on the position of the metal in the electrochemical series. Metals below hydrogen in the electrochemical series cannot spontaneously displace it from dilute acids. Silver is below hydrogen in the electrochemical series, hence it cannot spontaneously displace hydrogen from dilute nitric acid as shown in the answer.
the answer to this question would be true just thought u should know lol xd
Answer: c = 0.39 cal/g°C or
1.63 J/g°C
Explanation: To find the specific heat of the metal we will use the formula of heat which is Q= mc∆T.
We will derive for c, c = Q / m∆T
25.0 cal/ 4.0 g ( 36°C - 20°C)
= 0.39 cal / g°C
Or we can convert calories to joules.
0.39 cal x 4.184 J/ 1 cal
= 1.63 J /g°C
