Answer:
Covalent
Explanation:
A molecule of C₂H₅OH has C-C, C-H, C-O, and O-H bonds.
A bond between A and B will be ionic if the difference between their electronegativities (ΔEN) is greater than 1.6.
No bond has a large enough ΔEN to be ionic.
C₂H₅OH is a covalent molecule.

Meteorologists also use satellites to observe cloud patterns around the world, and radar is used to measure precipitation. All of this data is then plugged into super computers, which use numerical forecast equations to create forecast models of the atmosphere.
Answer:
179Kj/mol
Explanation:
The equation for the reaction is:
CaO + 3C ⇒ CaC₂ + CO
₂
The formula for calculating the heat absorbed is:
∆Hf (Products) - ∆Hf (Reactants)
Using the heat of formation (∆Hf) for each component in the reaction
∆Hf Cao = -635kj/mol
∆Hf C = 0kj/mol
∆Hf CaC2 = -63kj/mol
∆Hf CO2 = -393.5
The heat absorbed = ( -63 + -393.5) – (-635)
= - 456 + 635
= 179kj/mol
Answer: The word ‘Data’ means collection of information in the form of numerical figures, or a set of given facts. A data is a collection of numbers gathered to give some information.
Explanation: Visual representation of data will help us to understand it better and remember the facts easily. Hope this helped! :)
