as a 15.1-gram sample of a metal absorbs 48.75 j of heat its temperature increases 25.0 k what is the specific heat capacity of
Leviafan [203]
Specific heat capacity (c) of a material is related to the Energy Absorbed (Q), mass of the material (m) and the change in temperature (T) by the following equation:

c= \frac{Q}{mT}

Substituting the values of Q, m and T in the above equation, we get:

c= \frac{48.75}{15.1*25}=0.129

So the specific heat capacity of the metal with given conditions will be 0.129 J/g.K

A chemist places a 100 g cube of each of the metals listed in the table on a separate hot plate. All of the hot plates are ident
Julli [10]
The lower the specific heat the faster the temperaature will change.


You can learn it from the formula:


Q = m * Cs * ΔT


You can solve for ΔT


ΔT = Q / ( m * Cs)


Given the heat (Q) and m (100 g) are equal for the five samples:


 ΔT = [Q / m] / Cs. = constat / Cs


So you see the inverse relation between the change of temperatura and the specific heat.


So, the order of change of temperature is given by the specific heat: the lower the specific heat the faster the change of temperature. 


With that analysis you can calculate the order in which the cubes will reach the target temperature.

Consider the reaction. 2c(s,graphite) h2= c2h2(g) Based on the equation and the information in the table, what is the enthalpy o
xxTIMURxx [149]
<h3>The enthalpy of the reaction : C.226.73 kJ</h3><h3>Further explanation</h3>

Delta H reaction (ΔH) is the amount of heat change between the system and its environment

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)

The change in enthalpy in the formation of 1 mole of the elements is called enthalpy of formation

Delta H reaction (ΔH) is the difference between product enthalpy and reactant enthalpy (Hp-Hr)

Reaction :

2C + H2 -> C2H2

(ΔH) reaction = (ΔH) product - (ΔH) reactants

(ΔH) reaction = (ΔH) C2H2 - ((ΔH) C + (ΔH) H2)

for free element (ΔH) it has zero value, so (ΔH) C and (ΔH) H2 have zero value

From the available data: Hf (kJ / mol) C2 H2 (g)=  226.73

then

(ΔH) reaction = ΔH) C2H2 - ((ΔH) C + (ΔH) H2)

(ΔH) reaction = 226.73 - (0 + 0)

(ΔH) reaction = 226.73 (answer C)
