Answer:
By comparing the bonds between C-H and O-H, the O-H bond has the greatest degree of polarity.
Explanation:
Based on bond electronegative values which is a measure of the ability of a atom in a chemical bond to pull the shared electrons closer to its self.
The electronegativity of an element characterizes the elements chemical reaction.
From the available bonds
Oxygen has an electronegativity value of 3.44 and Carbon 2.55, while Hydrogen has an electronegativity value of 2.20
Therefore the bond between carbon and hydrogen is much less polar than between oxygen and hydrogen.
The bond between oxygen and hydrogen has the greatest polarity.
Answer: Land absorbs heat energy and releases heat energy quickly. Water absorbs heat energy and releases heat energy slowly. Global convection currents are set up in the atmosphere because of the unequal heating of Earth's surfaces.
Explanation:
When a brick is heated to a temperature between 20°C and 150°C, it loses most of the water added to the clay during the preparation phase. ... When the temperature starts to rise over 600°C, chemical changes begin to occur in the clay which give the brick colour, hardness and durability.
Answer:
Depending on the thermometer, it may have the ability to go as high or low as melting, freezing or boiling point for water. Just make sure you know the boiling, melting and freezing points in Celsius, Fahrenheit and/or Kelvin and read your thermometer accordingly.
