Answer:
23dm
Explanation:
so you have to do 10g +13dm so the you have to times it by 3 three times
One end has a specific binding site for a particular amino acid and the other end the sequence that can pair with a codon, called an anticodon. The DNA code is translated into messenger RNA when the RNA polymerase binds to it and makes the mRNA copy.
7.5 mol of hydrogen would be needed to consume the available nitrogen.
Explanation:
When hydrogen reacts with nitrogen, ammonia is formed as shown below;
3H₂ (g) + N₂ (g) → 2NH₃ (g)
As seen from the equation, every 3 moles of H₂ react with a mole of N₂ to form 2 moles of NH₃.
The limiting factor in a chemical reaction is the reactant that gets depleted first.
Because the molar mass of nitrogen gas is approximately 28g/mol, 70g of nitrogen gas would be 2.5 moles.
The reaction ratio of nitrogen to hydrogen in the reaction is 1 : 3. The reaction would require 2.5 * 3 (7.5) moles of hydrogen for a complete reaction.
However since there are only 7g on hydrogen, (Remember 1 mole of H₂ is approximately 2g), the available moles of H₂ is 7 / 2 = 3.5
3.5 moles fall short of the 7.5 moles of H₂ required for a complete reaction. H₂ gets depleted first before N₂. The reaction would require 4 more moles of H₂.
Answer:
+375.2 KJ.
Explanation:
The balanced equation for the reaction is given below:
H₂ + F₂ —> 2HF ΔH = +536 KJ
From the balanced equation above,
2 moles of HF required +536 KJ .
Finally, we shall determine the heat required to produce 1.4 mol of hydrogen fluoride, HF. This is illustrated below:
From the balanced equation above,
2 moles of HF required +536 KJ .
Therefore, 1.4 moles of HF will require = (1.4 × 536)/2 = +375.2 KJ
Thus, +375.2 KJ of heat energy is required.
