Answer:
It will take 
to exhaust the supply
Explanation:
We have to apply unitary method to solve this problem.
Divide total petroleum reserve by petroleum consumption in each year to calculate estimated time.
Presently, 
joules of petroleum are being consumed per year.
Hence, applying unitary method, 
joules of petroleum can be consumed in 
In an atom there are the same number of protons as electrons to start with. The answer would be 65 aswell.
Answer:
The ribosome contains three grooves which are sites for the tRNA. The first codon is AUG, which is called a "start codon". ... So, the tRNA that has the anti-codon sequence of UAC carrying the amino acid Met bonds to the mRNA codon. Another tRNA bonds to the next codon in the next groove with the next amino acid
<u>Answer:</u> The number of moles of 
is 0.05 moles.
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Molarity of solution = 0.10 mol/L
Volume of solution = 1 L
Putting values in above equation, we get:
The chemical reaction for the ionization of sodium sulfate follows the equation:
By Stoichiometry of the reaction:
2 moles of sodium ions are produced by 1 mole of sodium sulfate
So, 0.10 moles of sodium ions will be produced by = 
of sodium sulfate.
Hence, the number of moles of is 0.05 moles.
Ionic bounds are formed due to the electrostatic attraction between oppositely charged ions in a chemical compound.
The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).
