Which of the following best describes acid anhydrides?
when hydrogen chloride is dissolved, the polar bond between hydrogen and chlorine allows the hydrogen to separate from the chlorine.
aqueous solutions that contain acids are able to conduct an electric current because of the presence of electrolytes, or ions.
when a strong base like sodium hydroxide is dissolved, large amounts of heat are released because the process is exothermic.
when carbon dioxide (co2) is dissolved in water, carbonic acid (h2co3) is formed. the carbonic acid acts as an acid by giving off hydrogen ions to water.
mass of bicycle = 10 kg
f = 168 n
a = 2.8 m/s²
f = ma divide each side by m, then
m = f/a
= 60 kg
m = mass of bicycle + naoki's mass. then
60 = 10 + naoki's mass subtract 10 from each side
naoki's mass = 50 kg
polymerase chain reaction (pcr) analysis
i would use this technique because it allows you to make millions of precise dna replications from 1 single sample of dna. it also has the advantage of analyzing minuscule sample sizes, even if they are degraded although they must not be contaminated with dna from other sources during the collection, storage, and transport of the sample.
answer : the correct option is, (d) 3200 joules
solution : given,
force applied = 1600 n
displacement = 2 m
formula used :
w = work done
f = applied force
d = displacement
now put all the given values in the above formula, we get the work done.
therefore, the amount of work done was, 3200 joules
