Giving brain thing Vicky made the following list to describe humidity:

It is the amount of water vapor in the air.
It is shown on weather maps in millimeters or in inches.
It can seen on cold surface as water droplets.

Which statement best describes why the list is incorrect?

A)It can be seen on hot surfaces as water droplets.

B) It is shown on weather maps as a percent.

C) It is the amount of moisture in the air.

D) It is the temperature of water in the clouds

Write the symbol for every chemical element that has atomic number greater than 3 and atomic mass less than 12.0 u.

Which statement describes covalent bases? they have hydroxide ions. they produce hydrogen ions. they are often amines. they are named the same as ionic compounds.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
