Calculate the enthalpy change, δh, for the process in which 14.5g of water is converted from liquid at 10.5∘c to vapor at 25.0∘c .

for water, δhvap = 44.0kj/mol at 25.0∘c and cs = 4.18 j/(g⋅∘c) for h2o(l).

What element is able to combine with itself and hydrogen to form large molecules ?

How would you expect the mrna codons that code for the amino acids that make up hemoglobin to compare between humans

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.
