Hydrogen-Hydrogen
Oxygen=Oxygen
A summary of the Law of multiple proportions is that if A and B form more than one compound, and B1 is the amount of element B which reacts with a fixed mass of A in compound 1, and B2 is the amount of B which reacts with the same fixed mass of B to form compound 2, then the ratio B1:B2 will be small whole numbers.
This law is rather simplistic, and given the range of compounds known today the definition of 'small' is now rather large... but, to answer the question:
in compound one 1.14133g of B reacts with 1g of A. (1.14133=53.3/46.7)
Answer:
Yes
Explanation:
Scientists using the latest microscopic technology have found they can move individual atoms around a surface at will, a breakthrough that could have profound implications in the ultra-small world of electronics and even in industry
The molarity and normality of 5.7 g of Ca(OH)2 in 450ml 0f solution is calculated as follows
molarity = moles/volume in liters
moles =mass/molar mass
= 5.7g/74g/mol = 0.077moles
molarity = 0.077/450 x1000= 0.17M
Normality = equivalent point x molarity
equivalent point of Ca(OH)2 is 2 since it has two Hydrogen atom
normality is therefore = 0.17 x2 = 0.34 N
