Explain how dalton’s atomic theory offered a convincing explanation of the observation that mass is conserved in chemical reacti
podryga [215]

Dalton's atomic theory was based on the law of conservation of mass which states that the matter can neither be created nor be destroyed but it can only transformed into one form or another. In a chemical reaction, total mass of the reactants will be equal to the total mass of the products.

Taking an example,

methane+oxygen\rightarrow \text{carbon dioxide}+water

CH_4+2O_2\rightarrow CO_2+2H_2O

Mass of CH_4 = 16g

Mass of 2O_2 = 2\times 32g

Total mass on reactant side = (16+2\times 32)

Total mass on reactant side = 80g

Mass of CO_2 = 44g

Mass of 2H_2O=2\times 18g

Total mass on product side = (44+2\times 18)

Total mass on product side = 80g

It is seen from the above example that the

total mass on reactant side = total mass on product side.

The solubility of a gas is 2.0 g/L at 50.0 kPa of pres-
RideAnS [48]

Answer:

That means, under 10.0kPa of pressure, 0.4g of gas can be dissolved in 1L

Explanation:

Based on Henry's law, the solubility of the gas is directly proportional to the pressure. The equation is:

P1S2 = P2S1

<em>Where P is pressure and S solubility of 1, initial state and 2, final state of the gas.</em>

Replacing:

P1 = 50.0kPa

S1 = 2.0g/L

P2 = 10.0kPa

S2 = ??

50.0kPa*S2 = 10.0kPa*2.0g/L

S2 = 0.4g/L

That means, under 10.0kPa of pressure, 0.4g of gas can be dissolved in 1L
