<span>1. The correct option is ADENOSINE TRIPHOSPHATE, ATP. ATP is the basic unit of energy transfer in the living cells. ATP is the principal energy source for metabolic functions, in the cells, ATP are consumed by endothermic metabolic reactions and they are produced by exothermic metabolic reactions.
2. To form ATP, A THIRD PHOSPHATE GROUP HAS TO BE ADDED TO ADP. ADP has two phosphate groups while ATP has three phosphate group. ADP is usulally converted to ATP by the addition of a single phosphate group.
3. ADP and ATP work together and the two can be interconverted. ATP can be hydrolysed to ADP and ADP can be converted to ATP by the addition of a single phosphate group. When energy is needed inside a cell, the ATP will split off one of its phosphate group and become ADP. This split off process produce a high qunatity of energy which is then available for the cell to use.</span>
Answer is: no reaction occurs.
No reaction occurs because magnesium (Mg) is less reactive than sodium (Na). Sodium is higher in activity series of metals and can not be reduced. <span> Metal X will replace another metal Y in a solution if X is higher in the activity series. </span>
This problem is providing the ratio of nitrogen to oxygen by mass in nitrogen monoxide, NO, as 7.0:8.0 and asks for the same ratio but in NO₂ and N₂O₇. After doing the calculations, the results are 7.0:16.0 and 1.0:4.0 respectively.
<h3>Mass ratios:</h3>
In chemistry, one can calculate the mass ratios in chemical formulas according to the atomic mass of each atom. In such a way, one knows the mass ratio of nitrogen to oxygen in NO is 7.0:8.0 because we divide the atomic mass of nitrogen by oxygens:
![\frac{14}{16}=\frac{7.0}{8.0}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B16%7D%3D%5Cfrac%7B7.0%7D%7B8.0%7D%20%20)
Now, for chemical formulas with subscripts, one must multiply the atomic mass of the element by the subscript in the formula, which is the case of NO₂ and N₂O₇ as shown below:
![NO_2:\frac{14}{16*2}=\frac{14}{32} =\frac{7.0}{16.0} \\ \\ N_2O_7:\frac{14*2}{16*7}=\frac{28}{112} =\frac{1.0}{4.0}](https://tex.z-dn.net/?f=NO_2%3A%5Cfrac%7B14%7D%7B16%2A2%7D%3D%5Cfrac%7B14%7D%7B32%7D%20%3D%5Cfrac%7B7.0%7D%7B16.0%7D%20%20%5C%5C%0A%5C%5C%0AN_2O_7%3A%5Cfrac%7B14%2A2%7D%7B16%2A7%7D%3D%5Cfrac%7B28%7D%7B112%7D%20%3D%5Cfrac%7B1.0%7D%7B4.0%7D%20)
Therefore, the results for NO₂ and N₂O₇ are 7.0:16.0 and 1.0:4.0 respectively
