sulphur cuz its weight is 32.065g
Explanation:
this is correct
plz mark me brainliest
I think the answer might be 51.14% since the formula had to equal a 100% just add 41.86 and 6.98 and subtract the sum to 100.
Answer:
Melting of snow
Evaporation of water from desk
Explanation:
Processes that increase the entropy of the universe are those processes that have an increased disorderliness. We should note that there are three principal states of matter which are the liquid, gas and solid. The gaseous state is the most disorderly while the solid is the least disorderly.
Now. We can see that the cooling of a hot cup of coffee is a process that needs or leads to a loss in temperature which obviously decreases disorderliness of the universe.
The melting of snow however is a process that leads to an increase in the disorderliness of the universe. It entails moving from the solid state to the liquid state. It tends to move to a more disordered state indicating an increase in the entropy of the universe.
The evaporation of water from the desk is quite similar to that above. Hence since we are moving from the liquid to the gaseous state via evaporation, we can state that the entropy of the universe has increased since we have moved from a state with a lesser degree of disorderliness to a state that is more disordered I.e from liquid to gaseous state.
There are 3 ions in one formula unit of (NH4)2CO3.
Ions present in Ammonium carbonate.(NH4)2CO3
(NH4)2CO3 is called Ammonium carbonate. The formula indicates that in one mole of ammonium carbonate, There are
- Two moles of ammonium ions,NH₄⁺ with valency of +1.
- 1 mole of Carbonate ions CO₃²⁻ with valency of -2.
When 1 mole of ammonium carbonate is dissolved in water it gives
(NH₄)₂CO₃ ₊ H₂O---->2NH₄⁺ ₊ CO₃²⁻
Ions present are 2NH₄⁺ and CO₃²⁻
