what is the percent yield of the given reaction if 40. g magnesium reacts with excess nitric acid to produce 1.7 g hydrogen gas? mg 2hno3⟶mg(no3)2 h2

2b2t

explanation:

2b2t

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

the ratio of the conjugate base to the acid required to attain the desired ph.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
