What else can I help you with?
The portion of an organic molecule that is responsible for special behavior or reactivety is called a reactive group True or False?
True. A reactive group in an organic molecule is a specific part of the molecule that is usually involved in chemical reactions due to its particular properties and structure.
In single replacemant reactions metals lower on the activity chart replace higher metals on a higher chart true of false?
True. Metals lower on the activity chart are more reactive and can displace metals higher on the chart in single replacement reactions. This is because the more reactive metal is better able to give up electrons and form positive ions in the reaction.
True or False The chemical reactivity of metals tends to increase from left to right across the periodic table?
False. The most chemically reactive metals are in the two leftmost columns.
Is true that krypton is larger than argon?
No, that's not true. Krypton (Kr) is larger than argon (Ar) in terms of atomic radius and atomic size. Krypton has more electron shells than argon, which contributes to its larger size. Therefore, krypton is indeed larger than argon.
Is Chilling a liquid will increase evaporation at the surface true or false?
It is not true.
Does nonmetals are highly reactive while metals are completely nonreactive?
It is not true; many metals are very reactive and several nonmetals are nonreactive.
Ancient rome never had a highly delovped system of government true or false?
the answer is false
True or false atoms of the halogens do not normally form chemical bonds?
False. Atoms of halogens, such as chlorine and fluorine, do form chemical bonds with other elements to achieve a stable electron configuration. Halogens are highly reactive and tend to form bonds with other elements to complete their outer electron shell.
Teenagers who start smoking are highly likely to smoke as adults true or false?
It is true
Ancient rome had a highly developed system of law and government true or false?
True
Is it true does the dermis which is highly vascularized accounting for the often pink color in the cheeks true?
true
Lithium is more active than aluminum true or false?
True. Lithium is more active than aluminum in terms of chemical reactivity. It is a highly reactive alkali metal, while aluminum is less reactive due to the protective oxide layer that forms on its surface. This difference in reactivity affects their behavior in various chemical reactions and applications.
True or false highly-directional antennas are generally concave dish-shaped devices?
true
Is it true that during the English Renaissance actors were highly regarded and admired?
false
The portion of an organic molecule that is responsible for special behavior or reactivety is called a reactive group True or False?
True. A reactive group in an organic molecule is a specific part of the molecule that is usually involved in chemical reactions due to its particular properties and structure.
True or False Elements of the halogen family lose one electron to become halide ions?
True. Elements of the halogen family readily lose one electron to attain a stable electron configuration and become halide ions with a negative charge. This makes them highly reactive and likely to form ionic bonds with other elements.
when There is no requirement to take action to identify and discipline those responsible for the unauthorized disclosure of Controlled Unclassified Information?
False
