Anon25 [30]

Answer:

1' and 5' carbon.

Explanation:

DNA is the genetic material of almost all the living organisms but exceptions are involved in case of some viruses that contains RNA as their genetic material.

The DNA consists of the nitrogenous base, dexoyribose pentose sugar and the phosphate group. The base is attached with the sugar on the 1' position. The phosphate group is linked with the sugar at 5 position of the dexoyribose sugar.

Thus, the correct answer is 1' and 5' carbon.

Y_Kistochka [10]

Answer: 1) 1.6 moles of HCl

2) 7.0 moles of HCl

3) 2.4 moles of hydrogen

4) 0.96 moles of HCl

Explanation:

The balanced chemical equation is:

Zn+2HCl\rightarrow ZnCl_2+H_2  

According to stoichiometry :

1 mole of Zn require = 2 moles of HCl

0.8 moles of Zn will require=\frac{2}{1}\times 0.8=1.6moles  of HCl

3.5 moles of Zn will require=\frac{2}{1}\times 3.5=7.0moles  of HCl

According to stoichiometry :

2 moles of HCl produce = 1 mole of H_2

4.8 moles of HCl will require=\frac{1}{2}\times 4.8=2.4moles  of H_2

According to stoichiometry :

1 mole of ZnCl_2 are produced by = 2 moles of HCl

0.48 moles of ZnCl_2 are produced by =\frac{2}{1}\times 0.48=0.96moles  of HCl

Blank Na2CO3 + blank Ag3P --&gt; blank Na3P + blank Ag2CO3
mezya [45]

Answer: __3__Na2CO3 + __2__Ag3P → __2__Na3P + __3__Ag2CO3

Explanation:

In balancing equations you need to make sure the number of atoms before the reaction should be equal to the number of atoms after the reaction.

Before the reaction: We had 6Na, 9CO, 6Ag and 2p

After the reaction: We have 6Na, 9CO, 6Ag and 2p

And now we are sure that atoms before the reaction are equal to atoms after the reaction
