Answer

The base is Ba(OH)2

Explanation

This equation follows the path of, acid +base---salt +water

H2S +Ba(OH)2------BaS +2H2O

Where H2S is the acid, Ba(OH) is the base and 2H2O is water.

Here, Barium hydroxide reacts with hydrogen sulfide to give barium sulfide and water.

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>
