Answer:
Carbon Dioxide = CO2
Explanation:
The synthesis of Malachite is seen in the chemical formula:
CuSO 4 . 5H2O(aq) + 2NaCO3(aq) --> CuCO 3 Cu(OH) 2 (s) + 2Na 2 SO 4 (aq) + CO 2 (g) + 9H 2 O(l)
The bubbles mentioned in the question hints that our interest is the compounds in their gseous phase (g).
Upon examining the chemical equation, only CO2 is in the gaseous state and hence the only one that can be formed as bubbles,

Answer:
The heat lost by the water
3.8 KJ
The heat gain by ice
= 228.76 J
The heat required to melt the ice
= 3340 J
Explanation:
Mass of ice cube
= 10 gm
Initial temperature of ice cube
= 0 °c
Mass of water
= 100 gm
Initial temperature of water
= 20 °c
Final temperature of mixture
= 10.93 °c
(a). Total heat lost by the water
(
-
)
⇒
100 × 4.184 (20 - 10.93)
⇒
3.8 KJ
This is the heat lost by the water.
(b). Heat gained by the ice cube
=

⇒
= 10 × 2.093 × ( 10.93 - 0)
⇒
= 228.76 J
This is the heat gain by ice.
(C). Heat required to melt the ice
=
× Latent Heat
⇒
= 10 × 334
⇒
= 3340 J
This is the heat required to melt the ice.
