Explanation:
For sulphur dioxide;
3.53 g of sulphur combines with 3.52 g of oxygen
1.00 g of sulphur combines with 1.00 × 3.52/ 3.53 = 0.997 g
For sulphur trioxide
6.00 of sulphur combines with 9.00 g of oxygen
1.00 g of sulphur combines with 1.00 × 9.00/6.00 =1.5 g
Ratio of mass of oxygen;
1 : 1.5
The law of multiple proportions states that, if two elements A and B combine to form more than one chemical compounds, then the various masses of element A which combines separately with a fixed mass of element B are in simple multiple ratio.
We can see that the mass of oxygen which combines separately with sulphur in sulphur dioxide and sulphur trioxide are in simple ratio of 1:1.5.
Answer:
False
Explanation:
The entropy is not always on the increase
Answer:
a.the same as
Explanation:
The temperature of each 400mL bucket is about the same as the temperature of the original bucket of paint.
This is because the temperature of the paint inside the bucket is not dependent on the amount of paint present.
- In this regard, the temperature is an intensive property.
- So each of the boxes will have a temperature that is the same as that of the original bucket.
- Each of the particles have the same amount of kinetic energy.
The following substance must be an A. Compound.
(3) Silver Nitrate and Aluminium Sulfate
<u>Explanation:</u>
Silver nitrate and aluminium sulphate reacts to form Aluminium nitrate and silver sulfate.
The reaction is shown below:
6AgNO₃ (aq) + Al₂(SO₄)₃ (aq) → 2Al(NO₃)₃ (aq) + 3Ag₂SO₄ (S)
From the balanced equation we can see that Ag₂SO₄ or silver sulfate is the precipitate formed.
Aluminium sulfate and silver nitrate both are chemical compounds. There are many reactions that uses net ionic equation like acid-base neutralization reaction, redox reaction, double displacement reaction etc.
