Answer is: Hess's law

Hess's Law of Constant Heat Summation, or just Hess's Law, states that the enthalpies of several intermediate reactions will be equal to the total net enthalpy of the reaction. This is due to the conservation of thermal energy across reactions.

Which of the following three court cases affected marriage and family planning?
mafiozo [28]

Answer:

Obergefell v. Hodges

Loving v. Virginia

Roe v. Wade

Explanation:

Obergefell v. Hodges & Loving v. Virginia were Supreme Court cases that had to do with marriage. <u><em>Obergefell v. Hodges</em></u> was the most recent case in 2015, ruling that same-sex couples have the constitutional right to marry. <u><em>Loving v. Virginia</em></u> (1967) was a case that outlawed the segregation-era ban on interracial marriage. Both cases ruled that the protections were guaranteed under the Equal Protection & Due Process Clauses in the 14th Amendment.

Roe v. Wade (1973) is a more disputed case, but the original ruling guaranteed a woman's right to abort her baby. The Due Process Clause regarding privacy was again argued here.

What are things that made jackson's political campaign and election significant in the history of american politics?
Nostrana [21]

The election of Andrew Jackson dramatically changed the US for several different reasons including:

1) He was an advocate for the "average citizen"- Andrew Jackson was dubbed the "Champion of the Common Man." He received this title because he was not an inherently wealthy man nor was he part of a family that was consistently in politics. Rather, he came from humble beginnings. This story inspired many American citizens.

2) His policies resulted in increased democracy in the US- Jackson helped to get rid of property qualifications and other restrictions to ensure that white farmers had the right to vote, regardless of how much property they owned.
