Answer:

2HNO_2(aq)+Ca(OH)_2(aq)\rightarrow H_2O(l)+Ca(NO_2)_2(aq)

Explanation:

Hello.

In this case, considering that the reaction between nitrous acid and calcium hydroxide yield both water and calcium nitrite as a neutralization chemical reaction:

HNO_2(aq)+Ca(OH)_2(aq)\rightarrow H_2O(l)+Ca(NO_2)_2(aq)

As it is not balanced due to the two nitrites at the right, we obtain:

2HNO_2(aq)+Ca(OH)_2(aq)\rightarrow H_2O(l)+Ca(NO_2)_2(aq)

Which means that 2 before the nitrous acid balance both nitrogen and oxygen.

Regards.

How many miles of C are in 32.6 g of C2H6
sammy [17]
32.6 grams divided by the molar mass of C2H6, which is 18.0584g/mol = 1.8 moles of C2H6.

As there are two carbon atoms per C2H6, we must multiply the number of moles of C2H6 by 2 to get the number of moles of Carbon which is 3.6 moles.
The answer is 3.6 moles.

Hope this helps.

Which is an example of a building block that helps form DNA? cytosine polypeptide ribose uracil
AnnyKZ [126]
<span>Cytosine is a building block of DNA,
 it is a component to DNAs base pairs and pairs with guanine (these pairs make up the rungs of its double helix)... it is not Ribose as plain Ribose has a hydroxyl group where a hydrogen atom should be if it were to be found in DNA and be deoxyribose (hence deoxyribonucleic acid and not ribonucleic acid since ribonucleic acid is RNA). Uracil is only found in RNA and actually takes Cytosine's place in the rungs of RNA and binds with guanine (although RNA is not in the conventional double helix shape and more resembles a protein in shape). Polypeptide is a long peptide chain and usually associated with proteins and not DNA....</span>
