Answer:
55641.656 × 10^23 molecules
Explanation:
Get the molar mass, multiply by amount of stuff, multiply by Avogadros number.
More detail in picture attached.
Hope it helps. Brainliest Appreciated. :)
Convert everything to one base unit (let's do ft/s in this case)
There are 660 ft in a furlong and 2 weeks or 1209600 seconds in a fortnight
Multiply 537,600furlong and 660 ft/furlong and divide by 1209600 to get 293.333ft/s
The race car is already in ft/s
There are 30.48 cm in 1 foot and 3600 seconds in 1 hour. Multiply 9,000,000 by 1/30.48 and 1/3600 to get 82.02ft/s
THe peregrine falcon is the fastest
Melting point is dependent on the intermolecular forces which means the bonds between the molecules of bromine as it is a simple molecular structure
The answer would be
A) synthesis
<span>Water can resist a greater external force than ethanol due to its greater surface tension.
Reason:
Surface Tension in liquids is caused by the cohesive forces among the molecules of liquids at the surface. Means the liquids molecules at the surface have a net attractive interactions with molecules beneath them and cause them to contract causing tension.
Now comparing water and ethanol, water has stronger intermolecular interactions than ethanol because water has two Hydrogen bongd donors (i.e. Hydrogens directly attached to oxygen atom) while ethanol has only one Hydrogen Bond Donors. This strong intermolecular interactions in water makes greater surface tension.</span>
