In your chemistry class, your instructor fills three different flasks with three different gases. She tells you that one gas is

carbon dioxide (CO2), one is oxygen (O2), and one is simply the mixture of the gases in the atmosphere (air).
She removes the stopper from each flask and quickly performs a splint test as shown in this video. You notice that the ember continues burning in the first flask, it reignites but does not blow itself out or pop in the second flask, and it is completely extinguished in the third flask.

Which gas was in each flask?
air
oxygen
carbon dioxide
Drag the name of each gas to the correct flask.

Thanks for your question!

The answer is science influencing technology, as it was discovered in a science experiment. It doesn't really influence society as much because it doesn't influence the way people act, just the how things work.

Hope this helped!

What is the ionic formula of the compound formed by Co3+ and the phosphorus ion? What is the name of the compound formed based o
klasskru [66]

Answer: The ionic formula of compound is CoP and the name is cobalt phosphide.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here element Co is having an oxidation state of +3 called as Co^{3+} cation and phosphprous forms P^{3-} anion with oxidation state of -3. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral CoP

The nomenclature of ionic compounds is given by:

1. Positive is written first followed by the oxidation state of metal in roman numerals in square brackets.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

Thus the name of CoP is cobalt phosphide.
