Answer:
Therefore the required function is
Therefore 25°C=57°F
Explanation:
F denotes temperature of Fahrenheit and C denotes temperature of Celsius.
Therefore the required function is
Putting C=25°C in above equation
⇒45 =F-32
⇒F=32+45
⇒F=57
Therefore 25°C=57°F
Pure substances contain a single type of chemical species, either element or compound. Elements cannot be further broken into simpler units by chemical methods. If we consider a sample of elements, it has a single type of atoms present in it. A compound has one or more atoms bound together chemically. Compounds can be broken down into simpler units by chemical means. When we consider a sample of a single compound say water, it has all the pure water molecules. Hence, elements and compounds are pure substances.
Answer:
C2H6
Explanation:
Carbon forms bonds with itself, this property is called catenation and Carbon also has a tendency to form multiple bonds, double or triple. ... For C2H6, carbon forms double bond with the other carbon, and each carbon has three hydrogen atoms attached to it.
