Answers

it stands for niobium which was discovered in 1801 by Charles Hatchett of Brittan. It is ussed in welding rods, air fraim systems, superconductive magnets. It gets its name from iobe, the daughter of King Tantalus of the Greek myth. Niobium was considered identical to Tantalum, named after Tantalus, until 1884. Resists corrosin due to an oxide film. It is used in aviation industry

 Colloids.  The particles are usually clumpy.

In a chemical compound, would you expect an oxide ion to be joined with one atom of calcium or one atom of potassium? Why?

Answers

I know what you're asking but I don't think the question is stated properly. Technically, an atom will not join with an "oxide" ion; i.e., the oxide ion is an atom of oxygen to which two electrons have been added. An oxide ion will add to 2 K ions or 1 Ca ion. The K ion has lost just one electron so it takes two of them to equal the 2- charge on the oxide ion whereas the Ca ion has lost two electrons and it takes only one of them to equal the charge on the oxide ion.

When an inflated balloon is exposed to cold air,a. the temperature inside the balloon rises.
b. the pressure inside the balloon rises.
c. the volume of the balloon decreases.
d. the volume of the balloon increases

Answers

The correct answerwould be C. The volume of the balloon will decrease. As depicted in Charles’Law which states that volume and temperature are directly proportional to each other,when the pressure of the gas is at a constant. When this theory is applied, theballoon will decrease in volume when it is exposed to cold air because the gas pressureinside the balloon remains the same. It is easier to remember this concept withthe equation V/T = K where V is volume, T is Temperature and K is constantpressure.
