Answer:
1.96 × 10²⁴ molecules
Explanation:
Step 1: Given data
Mass of ethanol (m): 150. g
Step 2: Calculate the number of moles (n) corresponding to 150. g of ethanol
The molar mass of ethanol is 46.07 g/mol.
150. g × 1 mol/46.07 g = 3.26 mol
Step 3: Calculate the number of molecules in 3.26 moles of ethanol
To convert moles into molecules, we need Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.
3.26 mol × 6.02 × 10²³ molecules/1 mol = 1.96 × 10²⁴ molecules
Their proteins become denatured
Yes that is true all cells have cytoplasm and cell membrane! hope this helps! ;D
The enthalpy of reaction for the given above and any other given can be calculated through the equation,
Hrxn = H(product) - H(reactants)
From reliable sources, the values of H of the substances.
H(NO) = 90.25 kJ/mol
H(O2) = 0 kJ/mol
H(NO2) = 33.18 kJ/mol
Substituting the known values,
Hrxn = (2)(33.18 kJ/mol) - (2)(90.25 kJ/mol)
Simplifying,
Hrxn = -114.14 kJ
<em>ANSWER: -114.14 kJ</em>
