When 0.5 moles of Zn react with 0.4 moles of HCL the limiting reactant will be HCL and excess reactant is Zn 0.3 moles excess and 0.2 moles Zn will be consumed in the reaction.

<h3>What is the limiting reactant in the given equation ?</h3>

STEP1- Write the balanced equation

            Zn +   2HCL   →  ZnCl₂  + H₂

STEP2- calculate the moles according to the reaction

             1mol of Zn requires  →  2moles of HCL

              0.5 moles of Zn requires→ 1mol of HCL

              Given moles of HCL is 0.4

STEP3- Apply unitary method

            0.5/x=1/0.4

             0.5×0.4= x

              0.2=x

STEP4- excess reagent left 0.5-0.2=0.3

Hence, the 0.3mole of excess Zn is left

An 80.0g sample of an unknown metal is at an initial temperature of 55.5oC. Afer 540 J of energy is absorbed by the metal, the t
Lunna [17]

Answer:

Specific heat of metal = 0.26 j/g.°C

Explanation:

Given data:

Mass of sample = 80.0 g

Initial temperature = 55.5 °C

Final temperature = 81.75 °C

Amount of heat absorbed = 540 j

Specific heat of metal = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

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

ΔT =  81.75 °C - 55.5 °C

ΔT =  26.25 °C

540 j = 80 g × c × 26.25 °C

540 j = 2100 g.°C× c

540 j / 2100 g.°C = c

c = 0.26 j/g.°C
