16 I think but I could be wrong lol
For machines such as a rake the output force is less than the input force. If the input force of the rake is 10 newtons and the output force is 5 Newtons mechanical advantage is .5
Answer:
Lithium Chloride would be the best one
Sodium Hydroxide would be the second best
Explanation:
This is because stronger intermolecular bonds require more energy to break. As this energy is supplied in the form of heat when boiling, substances with stronger bonds will have a higher boiling point. The order of strength of intermolecular forces is; London dispersion forces < dipole-dipole<span> < </span><span>Hydrogen bonding</span>
2 boxes of A
Because C=A+B
2 of A = 20 grams
at the other hand we have 2 of B =10
So 20 + 10 = 30 grams
