heat required: 169452 Joules

  • use the formula, Q = mcΔT

<u />

<u>Q is heat required, m is mass in kg, c is s.h.c , ΔT is change in temperature</u>

  • Here, the units of s.p.c and mass matches, in grams
  • if did not match, we have to convert into specific unit.

↪ Q = 1500 * 4.184 * (52-25)

↪ Q = 169452 J

  • Mass=1500g=m
  • ∆T=52-25=27°C
  • Specific heat capacity=c=4.184J/g°C

Apply thermodynamics

\\ \rm\rightarrowtail Q=mc\delta T

  • Q is heat

\\ \rm\rightarrowtail Q=1500(4.184)(27)

\\ \rm\rightarrowtail Q=169452J

What is the concentration, in m/v percent, of a solution prepared from 50 g NaCl and 2.5 L of solution?
Serjik [45]
When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.

At a certain temperature the rate of this reaction is first order in HI with a rate constant of :0.0632s
Shalnov [3]

Answer : The time taken for the reaction is, 28 s.

Explanation :

Expression for rate law for first order kinetics is given by :

k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}

where,

k = rate constant  = 0.0632

t = time taken for the process  = ?

[A_o] = initial amount or concentration of the reactant  = 1.28 M

[A] = amount or concentration left time 't' = 1.28\times \frac{17}{100}=0.2176M

Now put all the given values in above equation, we get:

0.0632=\frac{2.303}{t}\log\frac{1.28}{0.2176}

t=28s

Therefore, the time taken for the reaction is, 28 s.
