The insulating ability of a substance is a physical characteristic and not a chemical one. A physical property is a characteristic that distinguishes one type of matter from the other and can be observed without changing the identity of the substance. A chemical property describes how one substance changes into another in a chemical reaction.
Answer:
Percent error = 20%
Explanation:
The percent error is calculated using the following equation:
Percent error = |(approximate value - exact value)| / (exact value) x 100%
In this problem, the approximate value was 184 mL and the exact value was 230.0 mL
Percent error = |(184 mL - 230.0 mL)| / (230.0 mL) x 100% = 20%
the one main difference between a hurricane and a typhoon is the specific location where the storm takes place!!
typhoons and hurricanes can reach sustained winds of an averaging 74 mph.
Answer and Explanation:
A chemical formula is composed by chemical symbols (in letters, which indicate the chemical elements) and subscripts (numbers). For example, let see the chemical formula for <em>carbon dioxide</em>:
CO₂
The letters C and O are the chemical symbols for the elements carbon (C) and oxygen (O). The number 2 in subscript indicates that there are 2 atoms of O per molecule. The subscript 1 is generally not indicated in chemical formulae, so it is assumed that the number of atoms of C is 1.
Summarizing, the chemical formula CO₂ indicates us that the molecule if formed by 1 atom of the element carbon (C) and 2 atoms of the element oxygen (O).
