Answer:
the surface may become etheir scratchy and soft and that the surface may also be come heated up due to friction
Answer:
An ice rink has the least amount of friction.
- Any smooth surface has the least amount of friction.
I hope this helped at all.
5.30x10^22 x 261.35g/6.02x10^23 = 23.01 g Ba(NO3)2
Answer:
0.100 M AlCl₃
Explanation:
The variation of boiling point by the addition of a nonvolatile solute is called ebullioscopy, and the temperature variation is calculated by:
ΔT = W.i
Where W = nsolute/msolvent, and i is the Van't Hoff factor. Because all the substances have the same molarity, n is equal for all of them.
i = final particles/initial particles
C₆H₁₂O₆ don't dissociate, so final particles = initial particles => i = 1;
AlCl₃ dissociates at Al⁺³ and 3Cl⁻, so has 4 final particles and 1 initial particle, i = 4/1 = 4;
NaCl dissociates at Na⁺ and Cl⁻ so has 2 final particles and 1 initial particle, i = 2/1 = 2;
MgCl₂ dissociates at Mg⁺² and 2Cl⁻, so has 3 final particles and 1 initial particle, i = 3/1 = 3.
So, the solution with AlCl₃ will have the highest ΔT, and because of that the highest boiling point.
A plant is a living organism that uses chlorophyll in the chloroplasts to perform photosynthesis. The chemical equation of photosynthesis is
Sunlight(Photons)+ CO2+2H2O ----->C6H12O6+H2O+O2.(Not balanced) The reactants are carbon dioxide and water. The products are water and glucose with oxygen as a waste product.Photosynthesis can make a plant form a closed cycle as plants need to respire with oxygen which is a waste product of one of their reactions.
