What does the specific heat for a substance indicate?
o-na [289]

O the amount of heat required to increase the temperature of 1 gram by 1°C

Explanation:

The specific heat of a substance is the amount of heat required to increase the temperature of 1 gram of a substance by 1°C. It is an intensive property that is specific to every substance.

The unit is given as J/g⁻¹°C⁻¹ or J/g⁻¹K⁻¹

This related to the quantity of heat using the expression below:

             Q = mC∅

Q is the quantity of heat added

m is the mass

C is the specific heat

∅ is the temperature change.

Given the reaction: H2O2(l) ⇌ H2(g) + O2(g) The forward reaction is endothermic. Determine which of the following changes would
taurus [48]

Answer:

Option(II) and option (IV) are correct.

Explanation:

Here products are H_{2} and O_{2} and reactant is H_{2}O_{2}

(I) According to Le-chatelier principle,increase in H_{2}  will shift the equilibrium towards reactant side to keep the equilibrium constant unchanged.

(II) According to Le-chatelier principle,decrease in O_{2}  will shift the equilibrium towards product side to keep the equilibrium constant unchanged.

(III) Adding a catalyst will not change position of equilibrium. Catalyst only helps to achieve equilibrium in a lesser time.

(IV) As this reaction is an endothermic reaction therefore heat is consumed in formation of product. Therefore increase in temperature will lead to formation of more product to consume excess heat added.

(V) Pure solids and liquids do not affect position of equilibrium as their concentrations remain unchanged.

How many moles of N20 gas would have a volume of 3.8 L at 460 mmHg and 77°C?
Citrus2011 [14]

<u>We are given:</u>

Volume of gas = 3.8 L

Pressure = 460 mmHg

Temperature = 77°c = (77+273)K = 350K

<u>Converting the pressure to atm:</u>

Pressure(in atm)  = Pressure(in mmHg) / 760

Pressure = 460/760 = 0.6 atm

<u>Finding the number of moles:</u>

using the ideal gas equation:

PV = nRT                                         [where R is the universal gas constant]

<em>replacing the given values in this equation</em>

(0.6)(3.8) = n(0.082)(350)

n = (0.6*3.8)/(0.082*350)

n = 0.08 moles
