All molecules are made of similar type of atom true or false​
vichka [17]

Answer:

False

Explanation:

Not all molecules are compounds, since some molecules, such as oxygen gas (above image of molecule of-O2) or ozone (O3), consist only of one element or type of atom. Water is also a molecule because it is made from atoms that have been chemically combined.

What is the volume of 8.7 * 10 ^ 23 molecules of chlorine gas (Cl 2 ) ?
Mariana [72]

Answer:

32.3 dm³

Explanation:

Data given:

no. of molecules of Cl₂ = 8.7 x 10²³

Volume of chlorine gas (Cl₂) = ?

Solution:

First we have to find number of moles

For this formula used

    no. of moles = no. of molecules / Avogadros number

    no. of moles = 8.7 x 10²³ / 6.022 x 10²³

    no. of moles = 1.44 moles

Now we have to find volume of the gas

for this formula used

                      no. of moles = volume of gas / molar volume

molar volume = 22.4 dm³/mol

Put values in above equation

                 1.44 moles = volume of Cl₂ gas / 22.4 dm³/mol

rearrange the above equation

                 volume of Cl₂ gas = 1.44 moles x 22.4 dm³/mol

                volume of Cl₂ gas =  32.3 dm³

how do the components that process information in the ENIAC compare with the components that process in a modern laptop computer
STALIN [3.7K]
For starters, ENIAC was as big as a room and had many parts that don't even exist nowadays. It was operated by humans and broke down often. Information processing was a tedious and a difficult process. Modern components enable much faster data travel, fewer opportunities for the thing to break down, and an easier access for people to process data.
