The Law of Definite Proportions (or Proust's Law) states that in a single chemical compound (such as H2O or CO) the ratio of it's component elements is a fixed whole number ratio.
The Law of multiple proportions applies when two or more elements/compounds have multiple ways of combining into different compounds.
Prop is a chemical prefix. It was extracted from “propionic acid”. It serves as the number 3 when counting axial atoms in forming names of organic compounds.
It should be “Weather consists of several components that each contribute to the overall system.”
The specific heat means the heat absorbed when 1 g of the compound increase 1 ℃. So the specific heat is 41.71/(18.69*17)=0.131 J/(g*k).
Answer:
leading zeroes to the left of a decimal point. and trailing zeros to the left of an invisible decimal point.
Explanation:
- All nonzero digits are significant figures. Example: 713 has three significant figures. 18,991 has five significant figures.
- Zeros located between two nonzero digits are significant figures. Example: 505 has three significant figures. 17,009 has five significant figures.
- Zeros at the ends of numbers are only significant if there is a decimal point in the number. Example: 502.00 has five significant figures (5,0,2,0,0). 5020 has three significant figures (5,0,2) 100,000 has one significant figure (1)
- Zeros that come before the first nonzero digit are not significant. Example: 0.0007 has one significant figure (7). 0.0970 has three significant figures (9,7,0)
