Answer:
To write a chemical equation, the reactants should be written on the left, and the products should be written on the right and the coefficients should be written next to the symbols of entities to indicate the number of moles of a substance produced used in the chemical reaction.
Answer:
15.9994 amu
Explanation:
By definition 1 mole of any substance is the mass that contains 1 Avogadro's Number of particle. (=> 6.02 x 10²³ particles/mole).
1 mole Oxy => 15.9994 amu => contains 6.02 x 10²³ particles Oxy /mole
1 mole Sulfur => 32.064 amu => contains 6.02 x 10²³ particles Sulfur /mole
1 mole H₂O => 18 amu => contains 6.02 x 10²³ molecules of water / mole.
Explanation:
The difference among mRNA, tRNA and rRNA are:
mRNA: It carries DNA's protein building information from nucleus to the cytoplasm. It is also read as codons nucleotide triplet that indicate specific amino acids .
rRNA: The function of rRNA is to join amino acids to the peptide bonds.
tRNA: Delivers amino acids to the site of protein synthesis. It also has an anticodon that interact with specific codon of another nucleus.
The similarity among mRNA, rRNA and tRNA is that they all consists of ribonucleic acid and can exist outside the nucleus in eukaryotes.
Answer:
0.7 moles of Chlorine gas is required.
Explanation:
The reaction is balanced as follows:
2Na + 
------> 2NaCl
According to stoichiometry,
2 mole Sodium reacts with 1 mole Chlorine gas
∴1 mole Sodium reacts with 1/2 moles of Chlorine gas
∴1.4 mole sodium reacts with 1.4/2 moles of Chlorine gas
= 0.7 moles of Chlorine gas
So, 0.7 moles of Chlorine gas is required.
