Suppose that CO2 in the atmosphere was held at a constant, natural level for a few thousand years. Then, CO2 was added to double
jasenka [17]

Answer: Temperature before the increase in CO_2 was a few degrees lower than temperature after the increase.

Explanation:

According to Charle's Law which states that The volume of gas is directly proportional to the temperature of the gas, when pressure is kept constant.

(Volume)\propto (Temperature)

\frac{volume}{temperature}=constant (At constant Pressure)

With the increase in level CO_2 in atmosphere the increase in temperature of the atmosphere will be observed.

Hence, temperature before the increase in CO_2 was a few degrees lower than temperature after the increase.

In whare atoms in group 1 and atoms in group 18 different?
sdas [7]

Group 1 contains metals while group 18 contains noble gases.

So group 1 is different from group 18 as they both contains different types of atoms as group 1 contains metals while group 18 contains noble gases.

There is 1 valence shell electron in group 1 , they are highly reactive while valence shell of group 18 is fully filled and they are least reactive .

Write the resonance forms of ozone, O3, the component of the upper atmosphere that protects the Earth from ultraviolet radiation
aleksklad [387]

Answer:

The resonance forms of O3 are attached as an image.

Explanation:

A compound with different contributing structures comes together and forms a resonating or intermediate structure that best describes the properties of that compound.

The given compound is ozone, having the chemical formula  

O3 = 6 electrons * 3 = 18 electrons

O → prefers to have a complete their octet

The bonding electrons and lone pair electrons are radical electrons that are present on the oxygen atoms tend to delocalize and results in various resonating forms of O3.
