Answer:
<u>The final temperature of both substances at thermal equilibrium is 17.3°C</u>
Explanation:
<u>To calculate the final temperature of both substances at thermal equilibrium -:</u>
First , we calculate the heat of A1 cube as follows -
q= mSΔT
(where q = heat of the cube , m = mass of cube , S= specific heat of cube {0.902j/g°C}, T = Temperature )
Putting the values given in the question ,
°
°
Now , calculate the heat of water -
q=mSΔT
Putting values from the question ,
°
°
=
Now ,
Heat lost by water A1= Heat gained by water [negative sign about heat lost]
°
°
°=
°
= 17.3°C
<u>Therefore , the final temperature of both substances at thermal equilibrium is 17.3°C</u>
<u></u>

Hello!
The set of compounds that have the same empirical formula is b) N₂O₄ and NO₂.
The Empirical Formula is the most simple representation of the atom ratio in a chemical compound. Of the listed sets of compounds, the only in which the atom ratio is the same for both compounds is the pair N₂O₄ and NO₂ in which the atom ratio N:O is 1:2. The Empirical Formula for this pair is NO₂.
N₂O₄ has the same atom ratio as NO₂ but this formula has each atom multiplied by two. However, its Empirical Formula is the same.
Have a nice day!
Answer:
When zinc is added to the solution of iron sulphate, the colour of iron sulphate solution changes. It is because zinc is more reactive than iron, it displaces iron from its solution of iron sulphate and a grey precipitate of iron and a colourless solution of zinc sulphate is formed.
Explanation:
Zn(s) + FeSO4(aq) -----> ZnSO4(aq) + Fe(ppt.)
