Daniel [21]

Answer:

Acid - A compound that increases hydrogen ions (H+) when it is dissolved in a solution

pH - A value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water

Base - A compound that increases hydroxide ions (OH−) when it is dissolved in a solution

Litmus paper - Used to measure the pH of substances by determining their hydrogen ion concentration

Give the oxidation state of the metal species in each complex. ru(cn)(co)4 -
kogti [31]
The given complex ion is as follow,

                                              [Ru (CN) (CO)₄]⁻

Where;
            [ ]  =  Coordination Sphere

            Ru  =  Central Metal Atom  =  <span>Ruthenium

            CN  =  Cyanide Ligand

            CO  =  Carbonyl Ligand

The charge on Ru is calculated as follow,

                               Ru + (CN) + (CO)</span>₄  =  -1
Where;
            -1  =  overall charge on sphere

             0  =  Charge on neutral CO

            -1  =  Charge on CN

So, Putting values,


                               Ru + (-1) + (0)₄  =  -1

                               Ru - 1 + 0  =  -1

                               Ru - 1  =  -1

                               Ru  =  -1 + 1

                               Ru  =  0
Result:
          <span>Oxidation state of the metal species in each complex [Ru(CN)(CO)</span>₄]⁻ is zero.

An alkene with the molecular formula C8H16 undergoes ozonolysis to yield a mixture of (CH3)2C=O and (CH3)3CCHO. The alkene is:
aalyn [17]

Answer:

2,4,4-trimethyl-2-pentene yields mixture of (CH_{3})_{2}C=O and (CH_{3})_{3}CHO

Explanation:

In ozonolysis (hydrolysis step involve a reducing agent such as Zn, Me_{2}S etc.), a pi bond is broken to form ketone/aldehyde.

Ketone is formed from di-substituted side of double bond and aldehyde is formed from mono-substituted side of double bond.

Ozoznolysis involves two consecutive steps : (1) formation of ozonide, (2) hydrolysis of ozonide.

Hydrolysis can be done with/without using reducing agent. Carboxylic acid/carbon dioxide/ketone is produced when hydrolysis is done without using reducing agent.

Here, 2,4,4-trimethyl-2-pentene yields mixture of (CH_{3})_{2}C=O and (CH_{3})_{3}CHO

Reaction steps are shown below.

Through which conversion is energy released? adp to atp atp to adp nadp to nadph co2 and h2o to c6h12o6 and o2
aleksandrvk [35]
  • Energy transformation includes ATP and ADP. at the point when energy is delivered, the response will in general separate a bigger particle to a more modest structure.
  • For this situation, the bigger particle is ATP comprised of three phosphates bunches while ADP is just made out of two phosphate gatherings.
<h3>What is the energy source for the conversion of ADP and ATP?</h3>
  • The energy expected for the change of ADP into ATP is acquired from light during photosynthesis and from exothermic responses during cell breath in the two plants and creatures.
  • ADP is produced on hydrolysis of ATP and the energy released in the process is utilised to carry out various cellular processes.
