Carbon forms two oxides in which the weight of oxygen combines with 1 g of carbon
are 1.33 g and 2.66 g respectively. what law is in agreement with this observation?
give reasons.

This is based on the masses of one element, that will be combined with a fixed mass of the other element.

Explanation:

This is based on the masses of one element, that will be combined with a fixed mass of the other element. Thoses masses are in a ratio.

This state we can find in 'The Law of Multiple Proportions, which is part of Dalton's atomic theory

We see that in the 2 compounds, the masses of oxygen, that combine with a fixed mass of carbon , will be in proportion.

For the first oxide we have 1g carbon per 1.33 g Carbon

1g /1.33g  = 0.752

For the second oxide we have 1g carbon per 2.66g Carbon

1g/2.66g = 0.376

Dividing the mass O per g C of the second (larger value) compound:

2.66 / 1.33 = 2   which is the same as 0.752 / 0.376

thus, it means that the masses of oxygen that combine with carbon are in a 2:1 ratio.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
