A. In fixed proportions its really the only one that makes sence, You shouldn't need to look this one up. :)

In Fixed Proportions!

John Dalton, the father of modern chemistry, said that atoms combine in simple whole-number rations to form compounds.
No, there are only 4 states of matter: Commonly known are liquid, gas and solid. When you electrically charge a gas you get the fourth state of matter: plasma.
Dalton's Law of Partial pressures states the total pressure of gas in a container is the sum of the individual gases. The pressure of a balloon filled solely with oxygen will deviate from the pressure in a balloon filled with a mixture of gases.
When one element combine with the fix mass of another element to produce more than one compound the ratio of first element will be small ratio in whole number or simple multiple ratio . For example if 1gm of H combine seperatly with 3gm of C & 8gm of O than the ratio will be Hyrogen 1:1 Oxygen 8:8 Carbon 3:3
None of the above
Reflexive Postulate.
The Supplement Postulate states that if two angles form a linear pair, then they are supplementary.
That's not a postulate. It's a theorem. And you have stated it.
The SAS (Side-Angle-Side) postulate.
SAA Congruence Postulate states that if two angles and a side opposite one of the angles are the same, the triangles are congruent.
The perpendicular postulate states that if there is a line, as well as a point that is not on the line, then there is exactly one line through the point that is perpendicular to the given line.
You would use the AA Similarity Postulate to prove that the following two triangles are similar. True or false?
The SAS Postulate states if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
two
similar
There are 50 States, and have been since around 1959.
