No Neon<span> is a member of the noble gas family. Other elements in this family includes </span><span>helium, argon, krypton, xenon, </span><span>and </span><span>radon. </span><span>These gases are in </span>Group 18<span> (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or </span>argon.<span>

Answer:

it is 50%

Explanation:

62.9x50=3145

64.9x50=3245

3245+3145=6390

6390/100=63.9

A19.0g sample of brass, which has a specific heat capacity of 0.375·J*g^−1°C−, is dropped into an insulated container containing

djverab [1.8K]

Answer:

The final temperature is 20.3 °C

Explanation:

Considering that:-

Heat gain by water = Heat lost by brass

Thus,

$m_{water}\times C_{water}\times (T_f-T_i)=-m_{brass}\times C_{brass}\times (T_f-T_i)$

Where, negative sign signifies heat loss

Or,

$m_{water}\times C_{water}\times (T_f-T_i)=m_{brass}\times C_{brass}\times (T_i-T_f)$

For water:

Mass = 300.0 g

Initial temperature = 20.0 °C

Specific heat of water = 4.184 J/g°C

For brass:

Mass = 19.0 g

Initial temperature = 81.7 °C

Specific heat of water = 0.375 J/g°C

So,

$300.0\times 4.184\times (T_f-20.0)=19.0\times 0.375\times (81.7-T_f)$

$1255.2T_f-25104=582.1125-7.125T_f$

$1262.325T_f=25686.1125$

$T_f = 20.3\ ^0C$

<u>Hence, the final temperature is 20.3 °C</u>
