How many grams of CaC2 would make 23.6g C2H2 ?

Chemistry
1 answer:
Andrej [43]4 years ago
5 0

CaC2 + 2 H2O = C2H2 + Ca(OH)2

moles CaC2 = 485 g/64.1 g/mol=7.57  

moles H2O = 2 x 7.57 =15.1  

mass H2O = 15.1 mol x 18.02 g/mol=272.8 g  

moles C2H2 = 23.6 /26.038 g/mol=0.906  

moles CaC2 = 0.906  

mass CaC2 = 0.906 x 64.1 =58.1 g  

moles Ca(OH)2 = 55.3 / 74.092 =0.760  

moles H2O = 2 x 0.760 =1.52  

mass water = 18.02 x 1.52 =27.4 g

If a polypeptide synthesized by a ribosome contains 99 amino acids in the chain, how many codons (including the start and stop c
Rudiy27

Explanation:

<u>-101 mRNA codons</u>

<u />

In the genetic code, an amino acid is encoded by 3 nucleotides, while there are just 4 bases . Each amino acid is specifically encoded by a codon- a triplet sequence of nucleotides...

Thus 99 amino acids= 99 codon sequences.

...along with a start and stop codon, this would require 101 mRNA codons

Further Explanation:

The nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar does nitrogen bases which may contain single to double bond ring.

Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

RNA codons determine certain amino acids so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Cysteine and Uracil) Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

given the following chemical equation, determine how many grams of N2 are produced by 9.24 of H2O2 nd 6.56g of N2H4
taurus [48]
I think the chemical reaction is:<span>

N2H4 + 2 H2O2-> N2 + 4H2O

We are given the amount reactants allowed to react. This will be the starting point of the reaction. First, is to find the limiting reactant.

9.24 g H2O2 ( 1 mol / 34.02 g ) = 0.27 mol H2O2
6.56  g N2H4 ( 1mol / 32.06) = 0.20 mol N2H4

Since from the reaction we have 1:2 ratio of the reactants then the limiting reactant is hydrogen peroxide. We will use this to find the amount of N2 produced.

0.27 mol H2O2 ( 1 mol N2 / 2 mol H2O2 ) ( 14.01 g N2 / 1 mol N2) =1.89 g N2 </span>
