How can you recognize an alcohol?
gavmur [86]

Answer:

O D. It has an -OH group attached to the end of the molecule.

Explanation:

Some alcohols have hydroxyl group (OH) attached to the end of a molecule and some have it attached as a branch on the molecule

{ \rm{R - OH \:  : \: primary \: alcohol   \: (1 \degree)}}  \\  \\ { \rm{R -(OH) - R {}^{i}  \:  : secondary \: alcohol \: (2 \degree)}} \\  \\ { \rm{R - R {}^{i} (OH) - R {}^{ii}  \:  : tertiary \: alcohol \: (3 \degree)}}

  • R is aryl or alkyl group
  • OH is hydroxyl group

2 UO2+ + 4 H+U4+ + UO22+ + 2 H2O is second order in UO2+ and third order overall. Complete the rate law for this reaction in the
mr Goodwill [35]

Answer:

r=k[UO_2^+]^2[H^+]

Explanation:

The given reaction is :-

2UO_2^++4H^+\rightarrow U^{4+}+UO_2^{2+}+2H_2O

According to the law of mass action:-

The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.

Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.

The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.  

m = 2 =  is order with respect to UO_2^+

n = order with respect to H+

overall order = m+n = 3

n = 3 - m = 3 - 2 = 1

Rate law is:-

r=k[UO_2^+]^2[H^+]

Which products of photosynthesis does your body break down to be used for cellular respiration?
dedylja [7]

Answer:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
