Gold is actually very soft. If rings were made of pure gold they would bend and become disfigured. Other elements are added to give the ring its stability.

100% gold is too soft, and isn't nearly as durable as it needs to be.

The temperature of a 10g sample of iron was raised by 25.4ᵒC with the addition of 114 J
Sidana [21]

Answer:

28956J

Explanation:

Specific heat capacity is equal to mass × heat capacity × temperature change

Shc = mCtheta

= 10 × 114 ×25.4

= 28956J

A certain amount of gas at 25°C and at a pressure of 0.800 atm is contained in a glass vessel. Suppose that the vessel can withs
Korvikt [17]

The maximum temperature : a. 745 K

<h3>Further explanation</h3>

Given

Gas at 25°C(298 K) and at a pressure of 0.800 atm

Final pressure = 2 atm

Required

Final temperature

Solution

Gay Lussac's Law  

When the volume is not changed, the gas pressure in the vessel is proportional to its absolute temperature  

\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}

Input the value :

T₂=(P₂T₁)/P₁

T₂=(2 atm x 298 K)/0.8 atm

T₂ = 745 K = 472 °C

Calculate the reduced mass of a nitrogen molecule in which both nitrogen atoms have an atomic mass of 14.00. Do the same for a h
professor190 [17]

Answer:

Explanation:

To calculate the reduced mass of nitrogen molecule = Mn x Mn/ Mn + Mn

Mn = atomic mass of Nitrogen =  14.00

reduced mass = 14 x 14 /14 + 14 = 7

Similarly for HCl; reduced mass for a hydrogen chloride molecule = Mh x Mcl/Mh + Mcl

where Mh = atomic mass of hydrogen = 1.008

Mcl = atomic mass of chrorine = 34.97

reduced mass for HCl = 1.008 x 34.97 /1.008 + 34.97

= 0.97
