Answer:
Its ability to denature bacterial proteins
Explanation:
Ethanol is a rapid antimicrobial against bacteria, fungi and viruses. When 70% concentrated Ethanol is in contact with a single celled organism, the it coagulates the protein at a slower rate, creating enough time for it to penetrate the cell before coagulation can block it.This will make the whole cell coagulated thus killing the cell.
Answer:
your answer is (a) Copper Metal
Explanation:
The four bonds of carbon tetrachloride (CCl4<span>) are </span>polar, but the molecule isnonpolar<span> because the bond polarity is canceled by the symmetric tetrahedral shape. When other atoms substitute for some of the Cl atoms, the symmetry is broken and the molecule becomes </span>polar
A hydrogen bond is the electrostatic<span> attraction between two polar groups that occurs when a hydrogen (H) atom covalently bound to a highly </span>electronegative<span> atom such as </span>nitrogen. So In Terms nitrogen<span> (N), </span>oxygen<span> (O), or </span>fluorine<span> (F) help form The bonds</span>
Answer:
-255.4 kJ
Explanation:
The free energy of a reversible reaction can be calculated by:
ΔG = (ΔG° + RTlnQ)*n
Where R is the gas constant (8.314x10⁻³ kJ/mol.K), T is the temperature in K, n is the number of moles of the products (n =1), and Q is the reaction quotient, which is calculated based on the multiplication of partial pressures by the partial pressure of the products elevated by their coefficient divide by the multiplication of the partial pressure of the reactants elevated by their coefficients.
C₂H₂(g) + 2H₂(g) ⇄ C₂H₆(g)
Q = pC₂H₆/[pC₂H₂ * (pH₂)²]
Q = 0.261/[8.58*(3.06)²]
Q = 3.2487x10⁻³
ΔG = -241.2 + 8.314x10⁻³x298*ln(3.2487x10⁻³)
ΔG = -255.4 kJ
