b. water
c.a tritant
d. an acid
(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.

Answer:
For organic compounds, carbon and hydrogen are listed as the first elements in the molecular formula, and they are followed by the remaining elements in alphabetical order. For example, for butane, the molecular formula is C 4 H 10.
Explanation:
B. A new gas is observed in the form of bubbles
C. Red and yellow paint mixing to make orange
D. The temperature of the substance remains constant updates
To solve such this we must know the concept of chemical reaction. Therefore, the correct option is option B that is a new gas is observed in the form of bubbles.
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
The characteristics of chemical reaction are:
Evolution of a Gas
Change in temperature
Change in color
Formation of Precipitate
The evidence that a chemical reaction has occurred is a new gas is observed in the form of bubbles.
Therefore, the correct option is option B that is a new gas is observed in the form of bubbles.
