Answer: The true volume of the gas will be lower than predicted by the ideal gas law because the volume of the actual particles is more significant under high pressure.
Should be B, because one rotation is a day one revolution is a day(also to check I looked up the difference).
Answer:
22.4 g
Explanation:
We know we will need a balanced equation with molar masses, so let’s gather all the information in one place.
M_r: 2.016
4H₂O + 2NH₃ ⟶ 2NO₂ + 7H₂; Δ<em>H</em> = 216 kJ/mol NH₃
1. Calculate the <em>moles of NH₃
</em>
216 kJ ≡ 1 mol NH₃
Moles NH₃ = 685 × 1/216
Moles NH₃ = 3.171 mol NH₃
2. Calculate the <em>moles of H₂</em>
The molar ratio is 7 mol H₂:2 mol NH₃
Moles of H₂ = 3.171 × 7/2
Moles of H₂ = 11.10 mol H₂
3. Calculate the <em>mass of H₂</em>
Mass of H₂ = 11.10 × 2.016
Mass of H₂ = 22.4 g
Answer:
0.083

Explanation:
We're asked to find the molar concentration (molarity) of the HCl solution, given some titration measurements.
Let's first write the chemical equation for this neutralization reaction:
NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)
Since we're given the molarity and volume of the NaOH solution used, we can calculate the moles be using the molarity equation:
mol solute=(molarity)(L soln)
=(0.1molL)(0.0332L)=0.00332 mol NaOH
Since all the coefficients in the chemical equation are 1, the relative number of moles of HCl used is also 0.00332 mol.
Finally, let's use the molarity equation again to find the molarity of the HCl solution (given the volume of NaOH soln is 40 mL, which must be in liters when using molarity equations):
molarity=mol soluteL soln
=0.00332lmol HCl0.040lL=0.083M
The carbon atom(s) of pyruvate is(are) first converted to carbon dioxide by pyruvate dehydrogenase complex is the second number of carbon of pyruvate goes to oxidation and convert it to CO2 in Krebs cycle.
<h3>what is Krebs cycle ?</h3>
Krebs cycle is also known as citric acid cycle it is the conversion of sugar to the direct energy in the form of ATP which further goes to mitochondria as it is the power house of the human cell.
Pyruvate molecule release second number carbon from the chain and undergoes oxidation to form the CO2.
Therefore, second number carbon atom will converts to carbon dioxide.
