(2) low first ionization energy and high electronegativity
(3) high first ionization energy and low electronegativity
(4) high first ionization energy and high electronegativity
Answer:
low first ionization energy and low electronegativity
Explanation:
Metals are typically characterized by low first ionization energy and low electronegativity. This is because metals can easily lose electrons to become positive ions and do not attract electrons strongly.
Two properties that are typically associated with metals are low first ionization energy and low electronegativity. Therefore, the correct option is (1).
Ionization energy is the energy required to remove an electron from an atom. Metals have low first ionization energy because they can easily lose an electron to become positive ions. Electronegativity is a measure of the ability of an atom to attract electrons. Metals have low electronegativity because they do not attract electrons strongly.

(1) Br2(ℓ) (3) KBr(s)
(2) K(s) (4) KBr(aq)
Answer: (1) H+ ions in aqueous solution
Answer:
12 moles
Explanation:
The reaction will form carbonic acid:
CO₂ + H₂O ⇒ H₂CO₃
For 528 g of CO₂, the number of moles (n) will be:
n = mass/molar mass
n = 528/44.01
n = 12 moles of CO₂
The stoichiometry is 1 mol of CO₂ reacts with 1 mol of H₂O, so 12 moles of CO₂ need 12 moles of H₂O.

Hello. This question is incomplete. The full question is:
"…I have no motive, my friends, to deceive you. I am sincerely desirous to promote your welfare. Listen to me, therefore, while I tell you that you cannot remain where you now are. Circumstances that cannot be controlled, and which are beyond the reach of human laws, render it impossible that you can flourish in the midst of a civilized community. You have but one remedy within your reach. And that is, to remove to the West and join your countrymen, who are already established there. And the sooner you do this the sooner you will commence your career of improvement and prosperity….
— President Andrew Jackson, 1835
Which group of people was President Jackson
addressing? (1) African Americans (2) Asian Americans (3) Mexican Americans (4) Native American Indians"
Answer:
(4) Native American Indians
Explanation:
The text above shows a statement by President Andrew Jackson to the Native American population. Basically, the president is stating that the natives must leave their territory and move to the territory chosen by the government as appropriate for the natives. The president says that the natives must move because they will not be able to fit in and be part of the American population that was being established and because of the progress that was desired the lands of the indigenous territory would be necessary and required.
After being elected president in 1828, Andrew Jackson backed the expulsion of Native Americans from their homes, claiming that their survival depended on being kept apart from white people. Here Jackson is addressing Native American Indians. The correct option is 4.
