Answer:
ork out which of the displacement (S), initial velocity (U), acceleration (A) and time (T) you have to solve for final velocity (V).
If you have U, A and T, use V = U + AT.
If you have S, U and T, use V = 2(S/T) - U.
If you have S, U and A, use V = SQRT(U2 + 2AS)
Answer:

Explanation:
Aluminium reacts with iodine to form Aluminium iodide
![$2Al(s)+3I_{2}(s) \to Al_{2}I_{6}(s)$](https://tex.z-dn.net/?f=%242Al%28s%29%2B3I_%7B2%7D%28s%29%20%5Cto%20Al_%7B2%7DI_%7B6%7D%28s%29%24)
From the equation, it is clear that 3 moles of iodine reacts with 2 moles of Aluminium to form Aluminium iodide
We know
For 2 moles of Aluminium, ![$2=\frac{weight}{27}$\\ $weight=2 \times 27=54g$](https://tex.z-dn.net/?f=%242%3D%5Cfrac%7Bweight%7D%7B27%7D%24%5C%5C%20%24weight%3D2%20%5Ctimes%2027%3D54g%24)
3 moles of Iodine reacts with 54 g of Aluminium
? moles of iodine react with 50 g of Aluminium
Answer:
C₁₂H₂₂O₁₁ + H₂O → C₅H₁₂O₆ + C₆H₁₂O₆
Explanation:
Chemical equation:
C₁₂H₂₂O₁₁ + H₂O → C₅H₁₂O₆ + C₆H₁₂O₆
Source of sucrose:
Sucrose is present in roots of plants and also in fruits. It is storage form of energy. Some insects and bacteria use sucrose as main food. Best example is honeybee which collect sucrose and convert it into honey.
Monomers of sucrose and hydrolysis:
Sucrose consist of monomers glucose and fructose which are join together through glycosidic bond. Hydrolysis break the sucrose molecule into glucose and fructose. In hydrolysis glycosidic bond is break which convert the sucrose into glucose and fructose. Hydrolysis is slow process but this reaction is catalyze by enzyme. The enzyme invertase catalyze this reaction.
The given reaction also completely follow the law of conservation of mass. There are equal number of atoms of elements on both side of chemical equation thus mass remain conserved.
Volume= length•width•height
V=5•7•3
V= 105cm^3
