"Pure water is always 11.2% H and 88.8% O by mass" statement best supports the law of definite proportions.
<u>Option:</u> C
<u>Explanation:</u>
The law of Proust is basically about chemical compound which are comprises of its constituent elements in a fixed ratio but on origin and preparing process it does not rely. This law is also named as law of a definite proportion or composition or constant composition.
The atom of oxygen has an atomic mass of 16 while an atom of hydrogen has an atomic mass of 1. This implies that water consists of 11% hydrogen, and 89% oxygen. To produce water, the very same proportion of hydrogen and oxygen should always be mixed.
A salt can either be a basic salt or acidic salt. An acidic salt contains a weak base and a strong acid. The acid and base undergoes a neutralization reaction to produce an acidic salt and water. A basic salt contains a weak acid and a strong base. The acid and base undergoes a neutralization reaction to produce a basic salt and water.
D. Liquid to gas. This is the only answer that demonstrates molecules heating up and moving quicker.
<u>Given:</u>
Total Candium = 35
# of M&M = 15
# of Skittlitium = 12
# of Peanutttium = 8
<u>To determine:</u>
The relative abundance for each
<u>Explanation:</u>
Relative abundance = amount of each item in the sample/Sample total
M&M = 15/35 = 0.429 (or) 42.9 %
Skittlitium = 12/35 = 0.343 (or) 43.3 %
Peanuttium = 8/35 = 0.229 (0r) 22.9%
