How many total hydrogen (H) atoms are present in the reactants side of the equation C2H5OH+3O2→2CO2+3H2O?

Answers

Answer 1
Answer: there are 6 hydrogens on the reactants side
Answer 2
Answer:

Final answer:

The reactant side of the given chemical equation C2H5OH + 3O2 → 2CO2 + 3H2O contains six hydrogen atoms.

Explanation:

The chemical equation in question is C2H5OH + 3O2 → 2CO2 + 3H2O. This refers to the reaction of ethanol (C2H5OH) with oxygen (O2), producing carbon dioxide (CO2) and water (H2O). From the chemical equation, the reactants side contains one ethanol molecule containing six hydrogen atoms. Hence, in terms of reactants, the number of hydrogen atoms involved in the equation is 6.

The correct answers are carbon dating. Carbon or radiocarbon dating is a method that uses a mathematical equation and the half-life of decay to determine the exact date of a fossil. Carbon dating is the method that has the determination of the age of an organic matter. 

Compare Niger’s and Italy’s net migration rates on the chart above. What do these figures mean for the two countries?

Answers

I don't know your chart, but I can provide some data:

Niger's migration rate is -0.5/1000 people: this migration rate is negative, which means that more people leave Niger than enter it.

Italy's migration rate is 4.2/1000 people: this means that more people enter Italy and settle there than leave it.

Which of the following is a true statement about codons?A. 

A codon is a sequence of four nitrogenous bases.

 B. 

A codon is a sequence of three amino acids.

 C. 

In translation, an mRNA codon is recognized by its complementary amino acid.

 D. 

In translation, an mRNA codon is recognized by its complementary tRNA.

​

Answers

The statement which has been considered as true statement about codons is in translation, an mRNA codon is recognized by its complementary tRNA. Thus, option D is correct.

The anticodon of the tRNA hydrogen has been binds to the codon of the mRNA by the complementary base pairing.  If the Codon  of the mRNA is - 5' AGCTCA-3'. The anticodon of the tRNA would be - 3' GATCTG-5'

The events that has been occur during the eukaryotic translation elongation are codons in the mRNA are recognized by rRNAs, and tRNAs add the amino acid to the polypeptide chain.
